This is my database:
dragons
id, key, name, age, creation_date
users
id, name, user, pass
users_dragons
user_id, dragon_id
So this is my code for deleting dragons from the database that have a bigger key that the passed and belongs to a determination user. The SQL query works perfectly for deleting them but not for returning the array of keys from the deleted elements.
I tried using PreparedStatement but later I checked, as far as I know, that this class doesn't return arrays, and the CallableStatement is only for executing processes in the db, and I don't know how they return arrays.
String query = "" +
"DELETE FROM dragons " +
"WHERE id IN (SELECT d.id FROM dragons d, users u, users_dragons ud" +
" WHERE d.key > ?" +
" AND ud.dragon_id = d.iD" +
" AND ud.user_id in (select id from users where id = ?)) RETURNING key INTO ?";
CallableStatement callableStatement = connection.prepareCall(query);
int pointer = 0;
callableStatement.setInt(++pointer, key);
callableStatement.setInt(++pointer, credentials.id);
callableStatement.registerOutParameter(++pointer, Types.INTEGER);
callableStatement.executeUpdate();
return (int []) callableStatement.getArray(1).getArray();
The code is giving me the error, but is obvious because the CallableStatement needs a postgres function to run and not a simple SQL query
org.postgresql.util.PSQLException: This statement does not declare an OUT parameter.
Use { ?= call ... } to declare one.
at org.postgresql.jdbc.PgCallableStatement.registerOutParameter
.......
It would be really helpful how would be the correct JDBC algorithm to delete the elements from the database and return the array of keys of the deleted items.
You treat such a statement like a normal SELECT statement: use java.sql.PreparedStatement.executeQuery() or java.sql.Statement.executeQuery(String sql) to execute the statement and get a result set.
java.sql.CallableStatement is for calling Procedures (but you don't need it in PostgreSQL).
How to call an Oracle function which returns sys_refcursor using EclipseLink?
There is a documentation which states about calling a function, but not sure how to call a function which returns sys_refcursor.
http://eclipse.org/eclipselink/documentation/2.4/jpa/extensions/a_namedstoredfunctionquery.htm
I have tried as follows
#NamedStoredFunctionQuery(name = "findEmployees",
functionName = "getEmps",
parameters =
{ #StoredProcedureParameter(queryParameter = "user",
name = "username",
direction = Direction.IN,
type = String.class)
} ,
returnParameter = #StoredProcedureParameter(queryParameter = "c_cursor")
)
Oracle Function
CREATE or REPLACE FUNCTION getEmps (username varchar2)
RETURN SYS_REFCURSOR
AS
c_cursor SYS_REFCURSOR;
BEGIN
OPEN c_cursor FOR
SELECT * FROM employees where emp_no=username;
RETURN c_cursor;
However when I execute, I am getting the following errors
Internal Exception: java.sql.SQLException: ORA-06550: line 1, column 13:
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Error Code: 6550
Call: BEGIN ? := getEmps(username=>?); END;
bind => [=> c_cursor, S7845]
Query: DataReadQuery(name="findEmps" )
at org.eclipse.persistence.internal.jpa.QueryImpl.getDetailedException(QueryImpl.java:378)
at org.eclipse.persistence.internal.jpa.QueryImpl.executeReadQuery(QueryImpl.java:260)
at org.eclipse.persistence.internal.jpa.QueryImpl.getResultList(QueryImpl.java:469)
How can I resolve this issue?
I think you must specify the Direction of the functions parmeter
CREATE or REPLACE FUNCTION getEmps (username IN varchar2)
RETURN SYS_REFCURSOR
AS
c_cursor SYS_REFCURSOR;
BEGIN
OPEN c_cursor FOR
SELECT * FROM employees where emp_no=username;
RETURN c_cursor;
Try it, please !
Save the function on database and then execute it with FUNCTION call.
For example, i have an Oracle function called 'SUMACAMPO' that sums two columns of the DB:
And my query:
select Function('SUMACAMPO') from Table t
Java Code:
Query q = em.createQuery("select Function('SUMACAMPO') from Table t");
List<Object[]> resultado= q.getResultList();
LOG.info("Resultado consulta: {}",resultado);
so, the output of execute the query in LOG is:
Resultado consulta: [4413700]
i am working with store procedure
i.e
CREATE PROCEDURE test
(
#INPUTPARAM INT,
#OUTPUTPARAM VARCHAR(20)
)
AS
SELECT #OUTPUTPARAM=S.NAME+','+D.NAME
FROM STUDENT S,DEPARTMENT D
WHERE S.DEPTID=D.DEPARTID AND D.DEPARTID=#INPUTPARAM
BEGIN
END
how to get out parameter from java class using hibernate
please share code example
CREATE PROCEDURE test
(
#INPUTPARAM INT,
#OUTPUTPARAM VARCHAR(20) OUTPUT --<-- You need to use key word "OUTPUT" here
)
AS
BEGIN
SELECT #OUTPUTPARAM = S.NAME + ',' + D.NAME
FROM STUDENT S INNER JOIN DEPARTMENT D
ON S.DEPTID = D.DEPARTID --<-- Use New Syntax of join with On Clause
WHERE D.DEPARTID = #INPUTPARAM
END
EXECUTE Procedure
DECLARE #Var VARCHAR(20);
EXECUTE dbo.test
#INPUTPARAM = 1
#OUTPUTPARAM = #Var OUTPUT --<-- use OUTPUT key word here as well
SELECT #Var
The only way to do it is using em.createNativeQuery and talk directly with you DB Server in SQL.
Update:
Here is, how it could be done:
//get connection from em
Session session = (Session)em.getDelegate();
Connection conn = session.connection();
//Native SQL
final CallableStatement callStmt = conn.prepareCall("{call your.function(?)}");
callStmt.setLong(1, documentId);
callStmt.execute();
if (callStmt.getMoreResults()) {
ResultSet resSet = cStmt.getResultSet();
//Do something good with you result
resSet.close();
}
callStmt.close();
//Don't know if calling conn.close(); is a good idea. Since the session owns it.
Hope that helps a little.
Notes:
If you are using JPA 2.0, you can get the session using
Connection conn = em.unwrap(Session.class).connection();
If you are using JPA 2.1, you can call stored procedures directly
StoredProcedureQuery query = em.createNamedStoredProcedureQuery("ReadAddressById");
query.setParameter("P_ADDRESS_ID", 12345);
List<Address> result = query.getResultList();
I am using hibernate. I wrote a native sql query.
This query will be executed in sqlSever command prompt.
try
{
session=HibernateUtil.getInstance().getSession();
transaction=session.beginTransaction();
SQLQuery query = session.createSQLQuery("SELECT AP.PROJECT_NAME, AP.SKILLSET, PA.START_DATE, PA.END_DATE, RS.EMPLOYEE_ID, RS.EMPLOYEE_NAME, RS.REPORTING_PM FROM RESOURCE_MASTER RS,SHARED_PROPOSAL S, ACTUAL_PROPOSAL AP, PROJECT_APPROVED PA, PROJECT_ALLOCATION PL WHERE RS.EMPLOYEE_ID = PL.EMPLOYEE_ID AND PA.PROJECT_ID = PL.PROJECT_ID AND PA.SHARED_PROPOSAL_ID = S.SHARED_PROPOSAL_ID AND S.ACTUAL_PROPOSAL_ID=AP.ACTUAL_PROPOSAL_ID");
List<Object[]> obj=query.list();
Object[] object=new Object[arrayList.size()];
for (int i = 0; i < arrayList.size(); i++) {
object[i]=arrayList.get(i);
System.out.println(object[i]);
}
arrayList.get(0);
String name=(String)arrayList.get(0);
logger.info("In find All searchDeveloper");
}catch(Exception exception)
{
throw new PPAMException("Contact admin","Problem retrieving resource master list",exception);
}
I am getting the following exception: org.hibernate.MappingException: No Dialect mapping for JDBC type: -9
This query is executed in SqlServer command prompt. I mapped seven tables.
If I remove the ACTUAL_PROPOSAL AP table, it executes correctly.
please help me
The issue comes when the hibernate dialect is unable to find the corresponding java data type for the db column type. To solve it you need to specify the data type of each result item with addScalar() method.
for example,
sess.createSQLQuery("SELECT ID,NAME,BIRTHDATE FROM CATS")
.addScalar("ID", Hibernate.LONG)
//If u r using newer version of hibernate use new LongType()
//instead of Hibernate.LONG
.addScalar("NAME", Hibernate.STRING)
.addScalar("BIRTHDATE", Hibernate.DATE)
Read the API docs here or an example here.
Just as an update. ManuPK is correct but Hibernate.String, Hibernate.Date, Hibernate.Long are deprecated. See http://opensource.atlassian.com/projects/hibernate/browse/HHH-5138
I am writing a simple web application to call a stored procedure and retrieve some data.
Its a very simple application, which interacts with client's database. We pass employee id and company id and the stored procedure will return employee details.
Web application cannot update/delete data and is using SQL Server.
I am deploying my web application in Jboss AS. Should I use JPA to access the stored procedure or CallableStatement. Any advantage of using JPA in this case.
Also what will be the sql statement to call this stored procedure. I have never used stored procedures before and I am struggling with this one. Google was not much of a help.
Here is the stored procedure:
CREATE procedure getEmployeeDetails (#employeeId int, #companyId int)
as
begin
select firstName,
lastName,
gender,
address
from employee et
where et.employeeId = #employeeId
and et.companyId = #companyId
end
Update:
For anyone else having problem calling stored procedure using JPA.
Query query = em.createNativeQuery("{call getEmployeeDetails(?,?)}",
EmployeeDetails.class)
.setParameter(1, employeeId)
.setParameter(2, companyId);
List<EmployeeDetails> result = query.getResultList();
Things I have noticed:
Parameter names didn't work for me, so try using parameter index.
Correct sql statement {call sp_name(?,?)} instead of call sp_name(?,?)
If stored procedure is returning a result set, even if you know with only one row, getSingleResult wont work
Pass a resultSetMapping name or result class details
JPA 2.1 now support Stored Procedure, read the Java doc here.
Example:
StoredProcedureQuery storedProcedure = em.createStoredProcedureQuery("sales_tax");
// set parameters
storedProcedure.registerStoredProcedureParameter("subtotal", Double.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("tax", Double.class, ParameterMode.OUT);
storedProcedure.setParameter("subtotal", 1f);
// execute SP
storedProcedure.execute();
// get result
Double tax = (Double)storedProcedure.getOutputParameterValue("tax");
See detailed example here.
I am deploying my web application in Jboss AS. Should I use JPA to access the stored procedure or CallableStatement. Any advantage of using JPA in this case.
It is not really supported by JPA but it's doable. Still I wouldn't go this way:
using JPA just to map the result of a stored procedure call in some beans is really overkill,
especially given that JPA is not really appropriate to call stored procedure (the syntax will be pretty verbose).
I would thus rather consider using Spring support for JDBC data access, or a data mapper like MyBatis or, given the simplicity of your application, raw JDBC and CallableStatement. Actually, JDBC would probably be my choice. Here is a basic kickoff example:
CallableStatement cstmt = con.prepareCall("{call getEmployeeDetails(?, ?)}");
cstmt.setInt("employeeId", 123);
cstmt.setInt("companyId", 456);
ResultSet rs = cstmt.executeQuery();
Reference
JDBC documentation: Java SE 6
You need to pass the parameters to the stored procedure.
It should work like this:
List result = em
.createNativeQuery("call getEmployeeDetails(:employeeId,:companyId)")
.setParameter("emplyoyeeId", 123L)
.setParameter("companyId", 456L)
.getResultList();
Update:
Or maybe it shouldn't.
In the Book EJB3 in Action, it says on page 383, that JPA does not support stored procedures (page is only a preview, you don't get the full text, the entire book is available as a download in several places including this one, I don't know if this is legal though).
Anyway, the text is this:
JPA and database stored procedures
If you’re a big fan of SQL, you may be
willing to exploit the power of
database stored procedures.
Unfortunately, JPA doesn’t support
stored procedures, and you have to
depend on a proprietary feature of
your persistence provider. However,
you can use simple stored functions
(without out parameters) with a native
SQL query.
For a simple stored procedure that using IN/OUT parameters like this
CREATE OR REPLACE PROCEDURE count_comments (
postId IN NUMBER,
commentCount OUT NUMBER )
AS
BEGIN
SELECT COUNT(*) INTO commentCount
FROM post_comment
WHERE post_id = postId;
END;
You can call it from JPA as follows:
StoredProcedureQuery query = entityManager
.createStoredProcedureQuery("count_comments")
.registerStoredProcedureParameter(1, Long.class,
ParameterMode.IN)
.registerStoredProcedureParameter(2, Long.class,
ParameterMode.OUT)
.setParameter(1, 1L);
query.execute();
Long commentCount = (Long) query.getOutputParameterValue(2);
For a stored procedure which uses a SYS_REFCURSOR OUT parameter:
CREATE OR REPLACE PROCEDURE post_comments (
postId IN NUMBER,
postComments OUT SYS_REFCURSOR )
AS
BEGIN
OPEN postComments FOR
SELECT *
FROM post_comment
WHERE post_id = postId;
END;
You can call it as follows:
StoredProcedureQuery query = entityManager
.createStoredProcedureQuery("post_comments")
.registerStoredProcedureParameter(1, Long.class,
ParameterMode.IN)
.registerStoredProcedureParameter(2, Class.class,
ParameterMode.REF_CURSOR)
.setParameter(1, 1L);
query.execute();
List<Object[]> postComments = query.getResultList();
For a SQL function that looks as follows:
CREATE OR REPLACE FUNCTION fn_count_comments (
postId IN NUMBER )
RETURN NUMBER
IS
commentCount NUMBER;
BEGIN
SELECT COUNT(*) INTO commentCount
FROM post_comment
WHERE post_id = postId;
RETURN( commentCount );
END;
You can call it like this:
BigDecimal commentCount = (BigDecimal) entityManager
.createNativeQuery(
"SELECT fn_count_comments(:postId) FROM DUAL"
)
.setParameter("postId", 1L)
.getSingleResult();
At least when using Hibernate 4.x and 5.x because the JPA StoredProcedureQuery does not work for SQL FUNCTIONS.

How to retrieve Stored Procedure output parameter using JPA (2.0 needs EclipseLink imports and 2.1 does not)
Even though this answer does elaborate on returning a recordset from a stored procedure,
I am posting here, because it took me ages to figure it out and this thread helped me.
My application was using Eclipselink-2.3.1, but I will force an upgrade to
Eclipselink-2.5.0, as JPA 2.1 has much better support for stored procedures.
Using EclipseLink-2.3.1/JPA-2.0: Implementation-Dependent
This method requires imports of EclipseLink classes from "org.eclipse.persistence", so it is specific to Eclipselink implementation.
I found it at "http://www.yenlo.nl/en/calling-oracle-stored-procedures-from-eclipselink-with-multiple-out-parameters".
StoredProcedureCall storedProcedureCall = new StoredProcedureCall();
storedProcedureCall.setProcedureName("mypackage.myprocedure");
storedProcedureCall.addNamedArgument("i_input_1"); // Add input argument name.
storedProcedureCall.addNamedOutputArgument("o_output_1"); // Add output parameter name.
DataReadQuery query = new DataReadQuery();
query.setCall(storedProcedureCall);
query.addArgument("i_input_1"); // Add input argument names (again);
List<Object> argumentValues = new ArrayList<Object>();
argumentValues.add("valueOf_i_input_1"); // Add input argument values.
JpaEntityManager jpaEntityManager = (JpaEntityManager) getEntityManager();
Session session = jpaEntityManager.getActiveSession();
List<?> results = (List<?>) session.executeQuery(query, argumentValues);
DatabaseRecord record = (DatabaseRecord) results.get(0);
String result = String.valueOf(record.get("o_output_1")); // Get output parameter
Using EclipseLink-2.5.0/JPA-2.1: Implementation-Independent (documented already in this thread)
This method is implementation independent (don't need Eclipslink imports).
StoredProcedureQuery query = getEntityManager().createStoredProcedureQuery("mypackage.myprocedure");
query.registerStoredProcedureParameter("i_input_1", String.class, ParameterMode.IN);
query.registerStoredProcedureParameter("o_output_1", String.class, ParameterMode.OUT);
query.setParameter("i_input_1", "valueOf_i_input_1");
boolean queryResult = query.execute();
String result = String.valueOf(query.getOutputParameterValue("o_output_1"));
For me, only the following worked with Oracle 11g and Glassfish 2.1 (Toplink):
Query query = entityManager.createNativeQuery("BEGIN PROCEDURE_NAME(); END;");
query.executeUpdate();
The variant with curly braces resulted in ORA-00900.
If using EclipseLink you can use the #NamedStoredProcedureQuery or StoreProcedureCall to execute any stored procedure, including ones with output parameters, or out cursors. Support for stored functions and PLSQL data-types is also available.
See,
http://en.wikibooks.org/wiki/Java_Persistence/Advanced_Topics#Stored_Procedures
The following works for me:
Query query = em.createNativeQuery("BEGIN VALIDACIONES_QPAI.RECALC_COMP_ASSEMBLY('X','X','X',0); END;");
query.executeUpdate();
May be it's not the same for Sql Srver but for people using oracle and eclipslink it's working for me
ex: a procedure that have one IN param (type CHAR) and two OUT params (NUMBER & VARCHAR)
in the persistence.xml declare the persistence-unit :
<persistence-unit name="presistanceNameOfProc" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>jdbc/DataSourceName</jta-data-source>

<properties>
<property name="eclipselink.logging.level" value="FINEST"/>
<property name="eclipselink.logging.logger" value="DefaultLogger"/>
<property name="eclipselink.weaving" value="static"/>
<property name="eclipselink.ddl.table-creation-suffix" value="JPA_STORED_PROC" />
</properties>
</persistence-unit>
and declare the structure of the proc in the eclipselink-orm.xml
<?xml version="1.0" encoding="UTF-8"?><entity-mappings version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_2_0.xsd">
<named-stored-procedure-query name="PERSIST_PROC_NAME" procedure-name="name_of_proc" returns-result-set="false">
<parameter direction="IN" name="in_param_char" query-parameter="in_param_char" type="Character"/>
<parameter direction="OUT" name="out_param_int" query-parameter="out_param_int" type="Integer"/>
<parameter direction="OUT" name="out_param_varchar" query-parameter="out_param_varchar" type="String"/>
</named-stored-procedure-query>
in the code you just have to call your proc like this :
try {
final Query query = this.entityManager
.createNamedQuery("PERSIST_PROC_NAME");
query.setParameter("in_param_char", 'V');
resultQuery = (Object[]) query.getSingleResult();
} catch (final Exception ex) {
LOGGER.log(ex);
throw new TechnicalException(ex);
}
to get the two output params :
Integer myInt = (Integer) resultQuery[0];
String myStr = (String) resultQuery[1];
This worked for me.
#Entity
#Table(name="acct")
#NamedNativeQueries({
#NamedNativeQuery(callable=true, name="Account.findOne", query="call sp_get_acct(?), resultClass=Account.class)})
public class Account{
// Code
}
Note : in future if you decide to use default version of findOne then just comment the NamedNativeQueries annotation and JPA will switch to default
This answer might be helpful if you have entity manager
I had a stored procedure to create next number and on server side I have seam framework.
Client side
Object on = entityManager.createNativeQuery("EXEC getNextNmber").executeUpdate();
log.info("New order id: " + on.toString());
Database Side (SQL server) I have stored procedure named getNextNmber
You can use #Query(value = "{call PROC_TEST()}", nativeQuery = true) in your repository. This worked for me.
Attention: use '{' and '}' or else it will not work.
JPA 2.0 doesn't support RETURN values, only calls.
My solution was. Create a FUNCTION calling PROCEDURE.
So, inside JAVA code you execute a NATIVE QUERY calling the oracle FUNCTION.
From JPA 2.1 , JPA supports to call stored procedures using the dynamic StoredProcedureQuery, and the declarative #NamedStoredProcedureQuery.
To call stored procedure we can use Callable Statement in java.sql package.
Try this code:
return em.createNativeQuery("{call getEmployeeDetails(?,?)}",
EmployeeDetails.class)
.setParameter(1, employeeId)
.setParameter(2, companyId).getResultList();
persistence.xml
<persistence-unit name="PU2" transaction-type="RESOURCE_LOCAL">
<non-jta-data-source>jndi_ws2</non-jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties/>
codigo java
String PERSISTENCE_UNIT_NAME = "PU2";
EntityManagerFactory factory2;
factory2 = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
EntityManager em2 = factory2.createEntityManager();
boolean committed = false;
try {
try {
StoredProcedureQuery storedProcedure = em2.createStoredProcedureQuery("PKCREATURNO.INSERTATURNO");
// set parameters
storedProcedure.registerStoredProcedureParameter("inuPKEMPRESA", BigDecimal.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("inuPKSERVICIO", BigDecimal.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("inuPKAREA", BigDecimal.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("isbCHSIGLA", String.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("INUSINCALIFICACION", BigInteger.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("INUTIMBRAR", BigInteger.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("INUTRANSFERIDO", BigInteger.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("INTESTADO", BigInteger.class, ParameterMode.IN);
storedProcedure.registerStoredProcedureParameter("inuContador", BigInteger.class, ParameterMode.OUT);
BigDecimal inuPKEMPRESA = BigDecimal.valueOf(1);
BigDecimal inuPKSERVICIO = BigDecimal.valueOf(5);
BigDecimal inuPKAREA = BigDecimal.valueOf(23);
String isbCHSIGLA = "";
BigInteger INUSINCALIFICACION = BigInteger.ZERO;
BigInteger INUTIMBRAR = BigInteger.ZERO;
BigInteger INUTRANSFERIDO = BigInteger.ZERO;
BigInteger INTESTADO = BigInteger.ZERO;
BigInteger inuContador = BigInteger.ZERO;
storedProcedure.setParameter("inuPKEMPRESA", inuPKEMPRESA);
storedProcedure.setParameter("inuPKSERVICIO", inuPKSERVICIO);
storedProcedure.setParameter("inuPKAREA", inuPKAREA);
storedProcedure.setParameter("isbCHSIGLA", isbCHSIGLA);
storedProcedure.setParameter("INUSINCALIFICACION", INUSINCALIFICACION);
storedProcedure.setParameter("INUTIMBRAR", INUTIMBRAR);
storedProcedure.setParameter("INUTRANSFERIDO", INUTRANSFERIDO);
storedProcedure.setParameter("INTESTADO", INTESTADO);
storedProcedure.setParameter("inuContador", inuContador);
// execute SP
storedProcedure.execute();
// get result
try {
long _inuContador = (long) storedProcedure.getOutputParameterValue("inuContador");
varCon = _inuContador + "";
} catch (Exception e) {
}
} finally {
}
} finally {
em2.close();
}
the simplest way is to use JpaRepository
1- Create a stored procedure
CREATE PROCEDURE dbo.getEmployeeDetails
(
#employeeId int,
#companyId int
) AS
BEGIN
SELECT firstName,lastName,gender,address
FROM employee et
WHERE et.employeeId = #employeeId and et.companyId = #companyId
END
2- Create Entity
#Getter
#Setter
#ToString
#NoArgsConstructor
#AllArgsConstructor
#Entity
public class EmployeeDetails {
#Id
private String firstName;
private String lastName;
private String gender;
private String address;
}
3- Create Repository
public interface EmployeeDetailsRepository extends
JpaRepository<EmployeeDetails,String> {
#Query(value = "EXEC dbo.getEmployeeDetails #employeeId=:empId,
#companyId=:compId",nativeQuery =true)
List<EmployeeDetails> getEmployeeList(#Param("employeeId") Integer empId,
#Param("companyId") Integer compId);
}
4- create Controller
#CrossOrigin(origins = "*")
#RestController
#RequestMapping(value = "/api/employee")
public class EmployeeController {
#Autowired
private EmployeeDetailsRepository empRepo;
#GetMapping(value = "/details")
public ResponseEntity<List<EmployeeDetails>> getEmployeeDetails(#RequestParam
String empId, #RequestParam String compId) {
try {
List<EmployeeDetails> result = empRepo.getEmployeeList(
Integer.valueOf(empId),Integer.valueOf(compId));
return ResponseEntity.status(HttpStatus.OK).body(result);
}
catch (Exception ex)
{
return ResponseEntity.status(HttpStatus.EXPECTATION_FAILED).body(null);
}
}
}
you can now call http://localhost:8080/api/employee/details?empId=1&compId=25
If you're not too attached to calling this particular procedure with JPA or JDBC, you could use jOOQ, a third party library that generates stubs for all of your stored procedures to simplify calling them, and making the calls type safe.
Calling procedures returning unspecified cursors
In your particular case, the procedure returns an untyped, undeclared cursor (it could return several cursors and interleaved update counts). So, you could call the procedure like this with jOOQ:
GetEmployeeDetails proc = new GetEmployeeDetails();
proc.setEmployeeId(1);
proc.setCompanyId(2);
proc.execute(configuration);
// Iterate over potentially multiple results
for (Result<?> result : proc.getResults()) {
// Print the first result set (your employee query)
System.out.println(result);
// Use your implicit knowledge of the content of the query
// Without type safety
for (Record record : result) {
// All tables / columns are also generated
System.out.println("First name: " + record.get(EMPLOYEE.FIRSTNAME));
System.out.println("Last name: " + record.get(EMPLOYEE.LASTNAME));
System.out.println("Gender: " + record.get(EMPLOYEE.GENDER));
System.out.println("Address: " + record.get(EMPLOYEE.ADDRESS));
}
}
Using an actual table valued function, instead
Personally, I don't really like that feature of a few RDBMS (including SQL Server, MySQL) of returning arbitrary untyped cursors. Why not just declare the result type? SQL Server has powerful table valued functions. E.g. just use this syntax here:
CREATE FUNCTION getEmployeeDetails (#employeeId int, #companyId int)
RETURNS TABLE
AS RETURN
SELECT
firstName,
lastName,
gender,
address
FROM employee et
WHERE et.employeeId = #employeeId
AND et.companyId = #companyId
Now, you have the full type information associated with this function in your catalog, and if you're still using jOOQ, that information will be available to the code generator, so you can call the function like this:
for (GetEmployeeDetailsRecord record : ctx.selectFrom(getEmployeeDetails(1, 2))) {
System.out.println("First name: " + record.getFirstName());
System.out.println("Last name: " + record.getLastName());
System.out.println("Gender: " + record.getGender());
System.out.println("Address: " + record.getAddress());
}
Disclaimer: I work for the company behind jOOQ
