I'm trying to insert a new record into an MS SQL database, and I'm getting an exception I've never seen before. When I call executeUpdate the following exception is thrown:
com.microsoft.sqlserver.jdbc.SQLServerException: A result set was generated for update.
This is the Java code that produces the error:
// addComment method adds a new comment for a given requestId
public CommentBean addComment(CommentBean comment) {
PreparedStatement stmt = null;
INative nat = null;
Connection conn = null;
try {
nat = dbConn.retrieveNative();
conn = (Connection)nat.getNative("java.sql.Connection");
stmt = conn.prepareStatement(ADD_COMMENT);
stmt.setInt(1, comment.getRequestId());
stmt.setString(2, comment.getComment());
stmt.setString(3, new SimpleDateFormat("MM/dd/yyyy").format(comment.getDateCreated()));
stmt.setString(4, comment.getCreatedBy());
comment.setCommentId(stmt.executeUpdate()); // exception
} catch(Exception ex) {
System.err.println("ProjectRegistration::SQLDAO - addComment");
ex.printStackTrace();
} finally {
try {
if (stmt != null) stmt.close();
} catch (Exception e) {}
}
return comment;
}// end addComment
Where ADD_COMMENT is defined as a String:
private static final String ADD_COMMENT = "INSERT INTO RequestComments OUTPUT INSERTED.commentId VALUES(?,?,?,?)";
For the sake of being thorough, the table is defined as:
CREATE TABLE RequestComments (
commentId int NOT NULL PRIMARY KEY IDENTITY(1,1),
requestId int FOREIGN KEY REFERENCES Requests(requestId),
comment varchar(400),
dateCreated date,
createdBy varchar(12)
);
I don't think I'm doing anything terribly complicated here, but I can't think of why I'm getting this exception. I have a method in the same class which does the exact same type of insertion (literally the same query with a different table name and number of values), and it has no issues. Does anyone have any ideas on how to resolve this issue?
This particular error can also be caused by an INSERT-trigger, which has a SELECT-statement as a part of the trigger code.
To test whether this is the case, you can try:
using executeQuery(), instead of executeUpdate() - and display the result.
executing the insert in tool like MySQL Workbench, SQL Server Management Studio, or whatever flavour of database design tools are available for your DBMS, to see whether a result is returned.

I'm hoping this may help others looking at the same error message, as it did for me. My solution was to live with a call to executeQuery(), although it only handles an underlying issue, instead of fixing it.
This instruction stmt.executeUpdate() is not returning the commentId, it returns a ResultSet which you could then get the commentId from. Something like this,
ResultSet rs = stmt.executeQuery(); // Not update, you're returning a ResultSet.
if (rs.next()) {
comment.setCommentId(rs.getInt(1));
}
you are using OUTPUT in your insert query i.e you will get a resultset after your query executes and to hold that you need an object of class ResultSet to hold that data
SqlServer : When SET NOCOUNT is ON, the count is not returned. When SET NOCOUNT is OFF, the count is returned.
Connection conn = DriverManager.getConnection(connectDB,user,pwd);
String sql = " set nocount off;INSERT INTO test (name) values (1)";
PreparedStatement prepareStatement = conn.prepareStatement(sql,Statement.RETURN_GENERATED_KEYS);
System.out.println(prepareStatement.executeUpdate());
ResultSet generatedKeys = prepareStatement.getGeneratedKeys();
if(generatedKeys.next()){
System.out.println(generatedKeys.getString(1));
}

I've had a similar problem where after a while an insert on a autonumber table would give a "A result set was generated for update." at random. I use connection pooling and somehow the driver can get into a state where executeUpdate in combination with Statement.RETURN_GENERATED_KEYS doesn't work anymore. I found out that in this state an executeQuery does the trick, but in the initial state executeQuery does not work. This lead me to the following workaround:
PreparedStatement psInsert = connection.prepareStatement("INSERT INTO XYZ (A,B,C) VALUES(?,?,?)", Statement.RETURN_GENERATED_KEYS);
ResultSet rs = null;
try {
psInsert.setString(1, "A");
psInsert.setString(2, "B");
psInsert.setString(3, "C");
Savepoint savePoint = connection.setSavepoint();
try {
psInsert.executeUpdate();
rs = psInsert.getGeneratedKeys();
} catch (SQLServerException sqe)
{
if (!sqe.getMessage().equals("A result set was generated for update."))
throw sqe;
connection.rollback(savePoint);
rs = psInsert.executeQuery();
}
rs.next();
idField = rs.getInt(1);
} finally {
if(rs != null)
rs.close();
psInsert.close();
}

So, I'm trying to extract msgID and msgStatus values from database for each reference Id(variable msgRefList) stored in the list object and I'm trying to store these extracted values in String objects for further processing. But rs.next() method is returning false and hence it is not going into the while loop where the assignment statements are. I checked in database with the query that i'm using in the code and it shows one record in the result, but still rs.next() is returning false. Screenshot attached with the database results.
Below is the actual code that i'm using
List<String> msgRefList = listofRefrnceValues:
try {
Connection connect = connectToDB(ENV);
for(String reference: msgRefList){
String query="select ID, MSG_STS from TABLE where INSTR_ID = ?";
PreparedStatement stmt = connect.prepareStatement(query);
stmt.setString(1,reference);
ResultSet rs = stmt.executeQuery();
if(rs!=null){
while(rs.next()) {
P_MID = rs.getString("P_MID");
P_MSG_STS = rs.getString("P_MSG_STS");
}
}
}
}catch (Exception e) {
e.printStackTrace();
}
You have some typos in your SQL-Query-String in java. Instead of TABLE you probably meant MINF (your real table) also all of your properties don't have the prefix P_ and ID is probably MID. So change:
String query="select ID, MSG_STS from TABLE where INSTR_ID = ?";
To:
String query="select P_MID, P_MSG_STS from MINF where P_INSTR_ID = ?";
And you'll be fine.
I have a below query, which needs to select a row by using a column as key and return generated keys.

When i run this, I get below exception:
java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended
Please tell me the ways to fix this.
Also, Using JDk 1.6 and ojdbc6-11.2.0.4.jar
I suspect that when you use generated keys with a prepared statement, the Oracle JDBC driver adds the RETURNING INTO clause to the INSERT statement, and that the JDBC driver is too dim to realise that the RETURNING INTO clause can't be used with INSERT INTO ... SELECT ... statements. I get the same ORA-00933 error if I attempt to run an INSERT INTO ... SELECT ... RETURNING ... statement.
What you could try instead is a PL/SQL block where we fetch the 'old' row into a record and then use an INSERT ... VALUES statement with a RETURNING_INTO clause to insert the values into the 'new' row:
DECLARE
l_row t_tpms_cc_request%ROWTYPE;
BEGIN
SELECT * INTO l_row FROM t_tpms_cc_request WHERE order_id = ?;
INSERT INTO t_tpms_cc_request (some_column, some_other_column, ...)
VALUES (l_row.some_column, l_row.some_other_column, ...)
RETURNING order_id INTO ?;
END;
As we're returning values from this, we need to prepare this as a CallableStatement instead of a PreparedStatement, and we need to register parameter 2 as an out parameter. We can then use this out parameter, instead of the getGeneratedKeys() method you're using at the moment, to return the generated key value.
Clearly this approach is Oracle-specific and won't work on other databases. I don't know how much of an issue database portability is to you, nor whether you can return generated keys from an INSERT INTO ... SELECT ... statement in other databases.
Is there a way to retrieve the auto generated key from a DB query when using a java query with prepared statements.
For example, I know AutoGeneratedKeys can work as follows.
stmt = conn.createStatement();
stmt.executeUpdate(sql, Statement.RETURN_GENERATED_KEYS);
if(returnLastInsertId) {
ResultSet rs = stmt.getGeneratedKeys();
rs.next();
auto_id = rs.getInt(1);
}
However. What if I want to do an insert with a prepared Statement.
String sql = "INSERT INTO table (column1, column2) values(?, ?)";
stmt = conn.prepareStatement(sql);
//this is an error
stmt.executeUpdate(Statement.RETURN_GENERATED_KEYS);
if(returnLastInsertId) {
//this is an error since the above is an error
ResultSet rs = stmt.getGeneratedKeys();
rs.next();
auto_id = rs.getInt(1);
}
Is there a way to do this that I don't know about. It seems from the javadoc that PreparedStatements can't return the Auto Generated ID.
Yes. See here. Section 7.1.9. Change your code to:
String sql = "INSERT INTO table (column1, column2) values(?, ?)";
stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
stmt.executeUpdate();
if(returnLastInsertId) {
ResultSet rs = stmt.getGeneratedKeys();
rs.next();
auto_id = rs.getInt(1);
}
There's a couple of ways, and it seems different jdbc drivers handles things a bit different, or not at all in some cases(some will only give you autogenerated primary keys, not other columns) but the basic forms are
stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
Or use this form:
String autogenColumns[] = {"column1","column2"};
stmt = conn.prepareStatement(sql, autogenColumns)
Yes, There is a way. I just found this hiding in the java doc.
They way is to pass the AutoGeneratedKeys id as follows
String sql = "INSERT INTO table (column1, column2) values(?, ?)";
stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
I'm one of those that surfed through a few threads looking for solution of this issue ... and finally get it to work. FOR THOSE USING jdbc:oracle:thin: with ojdbc6.jar PLEASE TAKE NOTE:
You can use either methods:
(Method 1)
Try{
String yourSQL="insert into Table1(Id,Col2,Col3) values(SEQ.nextval,?,?)";
myPrepStatement = <Connection>.prepareStatement(yourSQL, Statement.RETURN_GENERATED_KEYS);
myPrepStatement.setInt(1, 123);
myPrepStatement.setInt(2, 123);
myPrepStatement.executeUpdate();
ResultSet rs = getGeneratedKeys;
if(rs.next()) {
java.sql.RowId rid=rs.getRowId(1);
//what you get is only a RowId ref, try make use of it anyway U could think of
System.out.println(rid);
}
} catch (SQLException e) {
//
}
(Method 2)
Try{
String yourSQL="insert into Table1(Id,Col2,Col3) values(SEQ.nextval,?,?)";
//IMPORTANT: here's where other threads don tell U, you need to list ALL cols
//mentioned in your query in the array
myPrepStatement = <Connection>.prepareStatement(yourSQL, new String[]{"Id","Col2","Col3"});
myPrepStatement.setInt(1, 123);
myPrepStatement.setInt(2, 123);
myPrepStatement.executeUpdate();
ResultSet rs = getGeneratedKeys;
if(rs.next()) {
//In this exp, the autoKey val is in 1st col
int id=rs.getLong(1);
//now this's a real value of col Id
System.out.println(id);
}
} catch (SQLException e) {
//
}
Basically, try not used Method1 if you just want the value of SEQ.Nextval, b'cse it just return the RowID ref that you may cracked your head finding way to make use of it, which also don fit all data type you tried casting it to! This may works fine (return actual val) in MySQL, DB2 but not in Oracle.
AND, turn off your SQL Developer, Toad or any client which use the same login session to do INSERT when you're debugging. It MAY not affect you every time (debugging call) ... until you find your apps freeze without exception for some time. Yes ... halt without exception!
Connection connection=null;
int generatedkey=0;
PreparedStatement pstmt=connection.prepareStatement("Your insert query");
ResultSet rs=pstmt.getGeneratedKeys();
if (rs.next()) {
generatedkey=rs.getInt(1);
System.out.println("Auto Generated Primary Key " + generatedkey);
}
I have my Java program and I need to get data from my MYSQL DB,
I wrote this one out but its just sysout so getting data from my class and not using the Prepared Statement (I can delete the first 3 lines and it will work the same )
Could use some help to figure out how to get data from my DB and print it out
public void viewClientDetails(ClientsBean client) {
try {
PreparedStatement ps = connect.getConnection().prepareStatement(
"SELECT * FROM mbank.clients WHERE client_id = ?");
ps.setLong(1, client.getClient_id());
System.out.println(client.getClient_id());
System.out.println(client.getName());
System.out.println(client.getType());
System.out.println(client.getPhone());
System.out.println(client.getAddress());
System.out.println(client.getEmail());
System.out.println(client.getComment());
} catch (SQLException e) {
e.printStackTrace();
JOptionPane.showMessageDialog(null,
"Problem occurs while trying to see client details");
}
}
Well you're not actually executing the prepared statement... you're just preparing it. You should call PreparedStatement.executeQuery and use the ResultSet it returns:
// ...code as before...
try (ResultSet results = ps.executeQuery()) {
while (results.next()) {
// Use results.getInt etc
}
}
(You should use a try-with-resources statement to close the PreparedStatement too - or a manual try/finally block if you're not using Java 7.)
You need to do executeQuery on the preparedstatement to get a result set back of the query you performed.
You are simply not executing the query. Add a PreparedStatement.executeQuery() call. And fetch the results from the returned ResultSet.
For example:
PreparedStatement ps = connect.getConnection().prepareStatement("SELECT * FROM mbank.clients WHERE client_id = ?");
ps.setLong(1, client.getClient_id());
ResultSet rs = ps.executeQuery();
while (rs.next()) {
String userid = rs.getString("id");
String username = rs.getString("name");
}
As #Jon Skeet pointed out, the declaration of ResultSet in Java 7 is updated to:
public interface ResultSet extends Wrapper, AutoCloseable
It is AutoClosable now, which means that you can and should use the try-with-resource pattern.
You can do the below.
PreparedStatement ps = connect.getConnection().prepareStatement(
"SELECT * FROM mbank.clients WHERE client_id = ?");
resultSet = ps.executeQuery();
while (resultSet.next()) {
String user = resultSet.getString("<COLUMN_1>");
String website = resultSet.getString("<COLUMN_2>");
String summary = resultSet.getString("<COLUMN_3>");
}

How to get a value from the last inserted row? [duplicate]
(14 answers)
Closed 9 years ago.
Is there some way to get a value from the last inserted row?
I am inserting a row where the PK will automatically increase due to sequence created, and I would like to get this sequence number. Only the PK is guaranteed to be unique in the table.
I am using Java with a JDBC and Oracle.
I forgot to add that I would like to retrieve this value using the resultset below. (I have tried this with mysql and it worked successfully, but I had to switch over to Oracle and now I get a string representation of the ID and not the actually sequence number)
Statement stmt = conn.createStatement();
stmt.executeUpdate(insertCmd, Statement.RETURN_GENERATED_KEYS);
stmt.RETURN_GENERATED_KEYS;
ResultSet rs = stmt.getGeneratedKeys();
if(rs.next()){
log.info("Successful insert");
id = rs.getString(1);
}
The above snippet would return the column int value stored in a mysql table. But since I have switched over to Oracle, the value returned is now a strange string value.
What you're trying to do is take advantage of the RETURNING clause. Let's setup an example table and sequence:
CREATE TABLE "TEST"
( "ID" NUMBER NOT NULL ENABLE,
"NAME" VARCHAR2(100 CHAR) NOT NULL ENABLE,
CONSTRAINT "PK_TEST" PRIMARY KEY ("ID")
);
CREATE SEQUENCE SEQ_TEST;
Now, your Java code should look like this:
String insertSql = "BEGIN INSERT INTO TEST (ID, NAME) VALUES (SEQ_TEST.NEXTVAL(), ?) RETURNING ID INTO ?; END;";
java.sql.CallableStatement stmt = conn.prepareCall(insertSql);
stmt.setString(1, "John Smith");
stmt.registerOutParameter(2, java.sql.Types.VARCHAR);
stmt.execute();
int id = stmt.getInt(2);
This is not consistent with other databases but, when using Oracle, getGeneratedKeys() returns the ROWID for the inserted row when using Statement.RETURN_GENERATEDKEYS. So you need to use the oracle.sql.ROWID proprietary type to "read" it:
Statement stmt = connection.createStatement();
stmt.executeUpdate(insertCmd, Statement.RETURN_GENERATED_KEYS);
ResultSet rs = stmt.getGeneratedKeys();
oracle.sql.ROWID rid = (oracle.sql.ROWID) rs.getObject(1);
But this won't give you the generated ID of the PK. When working with Oracle, you should either use the method executeUpdate(String sql, int[] columnIndexes) or executeUpdate(String sql, String[] columnNames) instead of executeUpdate(String sql, int autoGeneratedKeys) to get the generated sequence value. Something like this (adapt the value to match the index or the name of your primary key column):
stmt.executeUpdate(INSERT_SQL, new int[] {1});
ResultSet rs = stmt.getGeneratedKeys();
Or
stmt.executeUpdate(INSERT_SQL, new String[] {"ID"});
ResultSet rs = stmt.getGeneratedKeys();
While digging a bit more on this, it appears that this approach is shown in the Spring documentation (as mentioned here) so, well, I guess it can't be totally wrong. But, unfortunately, it is not really portable and it may not work on other platforms.
You should use ResultSet#getLong() instead. If in vain, try ResultSet#getRowId() and eventually cast it to oracle.sql.ROWID. If the returned hex string is actually the ID in hexadecimal flavor, then you can try converting it to decimal by Long#valueOf() or Integer#valueOf().
Long id = Long.valueOf(hexId, 16);
That said, Oracle's JDBC driver didn't support ResultSet#getGeneratedKeys() for a long time and is still somewhat troublesome with it. If you can't get that right, then you need to execute a SELECT CURRVAL(sequencename) on the same statement as you did the insert, or a new statement inside the same transaction, if it was a PreparedStatement. Basic example:
public void create(User user) throws SQLException {
Connection connection = null;
PreparedStatement preparedStatement = null;
Statement statement = null;
ResultSet generatedKeys = null;
try {
connection = daoFactory.getConnection();
preparedStatement = connection.prepareStatement(SQL_INSERT);
preparedStatement.setValue(1, user.getName());
// Set more values here.
int affectedRows = preparedStatement.executeUpdate();
if (affectedRows == 0) {
throw new SQLException("Creating user failed, no rows affected.");
}
statement = connection.createStatement();
generatedKeys = statement.executeQuery(SQL_CURRVAL);
if (generatedKeys.next()) {
user.setId(generatedKeys.getLong(1));
} else {
throw new SQLException("Creating user failed, no generated key obtained.");
}
} finally {
close(generatedKeys);
close(statement);
close(preparedStatement);
close(connection);
}
}
Oh, from your code example, the following line
stmt.RETURN_GENERATED_KEYS;
is entirely superfluous. Remove it.
You can find here another example which I posted before about getting the generated keys, it uses the normal getGeneratedKeys() approach.
