Get result from Oracle SQL query - java

I have this Java Object which I will use to store counted elements from table:
private DCDataObj dc;
public class DCDataObj
{
private int datacenter; // Datacenters
.............
public DCDataObj()
{
}
public DCDataObj(int datacenter..........)
{
this.datacenter = datacenter;
..........
}
public int getDatacenter()
{
return datacenter;
}
public void setDatacenter(int datacenter)
{
this.datacenter = datacenter;
}
..........
}
I use this SQL query to count the components into the Oracle table:
ps = conn.prepareStatement("SELECT COUNT(1) AS CNT FROM COMPONENTSTATS CS, COMPONENTTYPE CT "
+ " WHERE CS.COMPONENTTYPEID = CT.COMPONENTTYPEID AND CT.COMPONENTTYPEID IN ( "
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ? " // 10
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ? " // 20
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ? " // 30
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ? ) " // 40
+ " GROUP BY CT.NAME ORDER BY CT.NAME");
ps.setInt(1, 1000);
......
I get the result using this Java code:
ResultSet result = ps.executeQuery();
while (result.next())
{
dc = new DCDataObj(
result.getInt(1),
result.getInt(2),
result.getInt(3),
...........
);
}
I get this problem when I execute the query:
java.sql.SQLException: Invalid column index
Can you help me how I can solve this problem?
UPDATE
The SQL query works. I get this result:
CNT
----------------------
1
1
1 1
I suspect that the problem is into the return type. I suppose that I get the result as array. But can I somehow inset the result from the query into the Java object without using Array?

On each line, you end with a "?" but the next line starts with another "?" without a comma. Then you wind up with part of the string looking like ", ? ?," which is invalid JDBC syntax. You need commas in between all your "?" placeholders.
Try this, with commas added at the end of your lines "10", "20", and "30".
ps = conn.prepareStatement("SELECT CT.NAME AS COMPONENT_TYPE, COUNT(1) AS CNT FROM COMPONENTSTATS CS, COMPONENTTYPE CT "
+ " WHERE CS.COMPONENTTYPEID = CT.COMPONENTTYPEID AND CT.COMPONENTTYPEID IN ( "
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, " // 10
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, " // 20
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, " // 30
+ " ?, ?, ?, ?, ?, ?, ?, ?, ?, ? ) " // 40
+ " GROUP BY CT.NAME ORDER BY CT.NAME");
EDIT
Now that I see your data, I see the problem. You cannot call getInt referencing the data, only the column header name or the 1-based column index. Also, your "COMPONENT_TYPE" is alphanumeric, please use getString instead of getInt. That also means you'll have to change your DCDataObj class to have a String for datacenter, not an int.
Try
dc = new DCDataObj(
result.getString("COMPONENT_TYPE"),
...........
);
or
dc = new DCDataObj(
result.getString(1),
...........
);

A colon in a bind variable or INTO specification was followed by an inappropriate name, perhaps a reserved word. You need to change the variable name and retry the operation. Did you try to get results from your query using pl/sql or SQL plus or your oracle terminal? Just to ensure you're executing the right query.

There is no column called "DATACENTER" fetched in the SELECT statement. It should be either COMPONENT_TYPE or CNT in result.getInt call.

MySQLSyntaxErrorException while i trying to update date in mysql with java

my error:
SEVERE: null
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE CustLogin LIKE 'patryk'' at line 1.
This is update:
"UPDATE customers SET CustPassword = ?, CustFirstName = ?," +
" CustLastName = ?, CustAddress = ?, CustCity = ?, CustProv = ?, CustPostal = ?," +
" CustCountry = ?, CustHomePhone = ?, CustBusPhone = ?, CustEmail = ?, AgentId = ?," +
" WHERE CustLogin LIKE ?";
kompilator has problem with stmt.executeUpdate();
there are screens code :
I think update don't have mistakes and database is working properly because for example, I can add customer
Do you have some ideas?
I think the error is because of the "," before WHERE CustLogin...
Replace it with,
"UPDATE customers SET CustPassword = ?, CustFirstName = ?," +
" CustLastName = ?, CustAddress = ?, CustCity = ?, CustProv = ?, CustPostal = ?," +
" CustCountry = ?, CustHomePhone = ?, CustBusPhone = ?, CustEmail = ?, AgentId = ?" +
" WHERE CustLogin LIKE ?";

Java subsequent DB2 insertions -845 error

I am getting -845 SQL codes on a table insert:
nested exception is org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL
[INSERT INTO PIM30_POL_DETAILS VALUES(PREVIOUS VALUE FOR PIM_ORDER_ID_SEQ, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, NULL)];
SQL state [51035]; error code [-845]; DB2 SQL Error: SQLCODE=-845, SQLSTATE=51035, SQLERRMC=SHELTRU.PIM_ORDER_ID_SEQ, DRIVER=4.17.29; nested exception is com.ibm.db2.jcc.am.SqlException: DB2 SQL Error: SQLCODE=-845, SQLSTATE=51035, SQLERRMC=SHELTRU.PIM_ORDER_ID_SEQ, DRIVER=4.17.29] with root cause
com.ibm.db2.jcc.am.SqlException: DB2 SQL Error: SQLCODE=-845, SQLSTATE=51035, SQLERRMC=SHELTRU.PIM_ORDER_ID_SEQ, DRIVER=4.17.29
The Java code for this is:
#Transactional
public String insertIntoDatabase(final List<Policy> pols, final InspectionOrder order, final OrderReason reason){
String toReturn = PolicyDAO.transactionTemplate.execute(new TransactionCallback<String>() {
#Override
public String doInTransaction(TransactionStatus status) {
SqlParameterSource params = new BeanPropertySqlParameterSource(order);
PolicyDAO.namedParemeterJdbcTemplate.update(Queries.getInsertInspOrder(), params);
for(Policy p : pols){
params = new BeanPropertySqlParameterSource(p);
PolicyDAO.namedParemeterJdbcTemplate.update(Queries.getInsertPolDetails(), params);
}
return "Successfully ordered inspection(s)";
}
});
if(toReturn.equals("Successfully ordered inspection(s)")) return toReturn;
else return "Failed to order inspection(s)";
}
Both INSERT statements use a sequence, the first one uses NEXT VALUE FOR PIM_ORDER_ID_SEQ and the second one uses PREVIOUS VALUE FOR PIM_ORDER_ID_SEQ. I presume that the second insertion is being called before the first insertion is finished as I only get the error 5-10% of the time.
What can I do to combat this?

PreparedStatement - syntax error

I have a problem with PreparedStatement.
This is my function that adds new user to MySQL database:
public static void createUser(String fn, String sn, String log, String pass, int accNum, String qst, String answ) {
try {
Connection conn = (Connection) mySQLConnector.getConnection();
PreparedStatement ps = (PreparedStatement) conn.prepareStatement(
"INSERT INTO users"
+ "(FirstName, LastName, Login, Password, AccountNumber, Ballance, Question, Answer)"
+ "VALUES (?, ?, ?, ?, ?, ?, ?, ?");
ps.setString(1, fn);
ps.setString(2, sn);
ps.setString(3, log);
ps.setString(4, pass);
ps.setInt(5, accNum);
ps.setDouble(6, 0);
ps.setString(7, qst);
ps.setString(8, answ);
ps.executeUpdate();
ps.close();
}
catch (SQLException e) {
e.printStackTrace();
}
}
And this is an error that I get:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
I have no idea what is wrong with my query. ColumnNames are ok, function arguments are also ok.
I've tried adding '' to columns names (like that: 'FirstName') but i t still doesn't work...
EDIT:
Adding spaces did not helped.I even made it in one line:
"INSERT INTO users (FirstName, LastName, Login, Password,
AccountNumber, Ballance, Question, Answer) VALUES (?, ?, ?, ?, ?, ?,
?, ?)"
and still gives the same error
You are missing spaces. Change your SQL to :
"INSERT INTO users " // space added
+ "(FirstName, LastName, Login, Password, AccountNumber, Ballance, Question, Answer) " // space added
+ "VALUES (?, ?, ?, ?, ?, ?, ?, ?)");
EDIT : I missed the missing closing bracket at the end of the VALUES clause.
I think you just need to add spaces and bracket
PreparedStatement ps = (PreparedStatement) conn.prepareStatement(
"INSERT INTO users "
+ "(FirstName, LastName, Login, Password, AccountNumber, Ballance, Question, Answer) "
+ "VALUES (?, ?, ?, ?, ?, ?, ?, ?)");
Fix this:
"VALUES (?, ?, ?, ?, ?, ?, ?, ?");
to this:
"VALUES (?, ?, ?, ?, ?, ?, ?, ?)";

SQLException - Generated keys not requested (MySQL)

I get this error when im making a new character to my game, in the CreateCharHandler it sends "saveToDb(false);" but when im ingame with another char i manually created i can saveToDb(true); with no error. please help, why is this happening?
http://i56.tinypic.com/oh1pn5.png
SaveToDb method http://pastebin.com/9sT5XBxp
line 3514 is:
ResultSet rs = ps.getGeneratedKeys();
Thanks in advance!
Your SQLException clearly states that:
You need to specify Statement.RETURN_GENERATED_KEYS to the
Statement.executeUpdate() or Connection.prepareStatement().
This can be achieved as follows (adding an additional value on Connection.prepareStatement() method):
String SQL = ""; //whatever my String is
PreparedStatement ps = connection.prepareStatement(SQL, Statement.RETURN_GENERATED_KEYS);
ps.setString(1, "value");
//Other necessary ps.setXXX() methods
//now update
ps.executeUpdate();
ResultSet rs = ps.getGeneratedKeys();
The Statement.RETURN_GENERATED_KEYS is key here.
Hope this helps!
PS: Useful resource.
#Charlie berg, since you prefer being lazy, I changed line 13 of your code to include the Statement.RETURN_GENERATED_KEYS:
ps = con.prepareStatement("INSERT INTO characters (level, fame, str, dex, luk, `int`, exp, hp, mp, maxhp, maxmp, sp, ap, gm, skincolor, gender, job, hair, face, map, meso, hpMpUsed, spawnpoint, party, buddyCapacity, messengerid, messengerposition, mountlevel, mounttiredness, mountexp, equipslots, useslots, setupslots, etcslots, monsterbookcover, watchedcygnusintro, vanquisherStage, dojopoints, lastDojoStage, finishedDojoTutorial, vanquisherKills, matchcardwins, matchcardlosses, matchcardties, omokwins, omoklosses, omokties, givenRiceCakes, partyquestitems, jailtime, accountid, name, world) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)", Statement.RETURN_GENERATED_KEYS);
Also, Statement class is of package java.sql (make sure you import correctly). :-)
Oracle Documents:
If there is no indication that auto-generated columns should be made
available for retrieval, a call to Statement.getGeneratedKeys will
return a null ResultSet.
You should explicitly tell to JDBC That you want generated keys.
like this:
Statement stmt = conn.createStatement();
stmt.executeUpdate(sql,Statement.RETURN_GENERATED_KEYS);
or
conn.prepareStatement(sql,Statement.RETURN_GENERATED_KEYS);
and then you can use getGeneratedKeys().

Problem with a prepared statement

I have this code:
Date start = new Date(Integer.parseInt(jTextField4.getText()), Integer.parseInt(jTextField16.getText()), Integer.parseInt(jTextField17.getText()));
Date end = new Date(Integer.parseInt(jTextField5.getText()), Integer.parseInt(jTextField18.getText()), Integer.parseInt(jTextField19.getText()));
statement = connection.createStatement();
preparedStatement1 = connection.prepareStatement("insert into sportmangg(customer_code,"
+ "sportman_code, start, finish, salary,amount,box salary,private salary, food salary, "
+ "other salary, bime salary, number) "
+ "values (? ,?, ? , ?, ?, ?, ?, ?, ?, ?, ?, ?");
preparedStatement1.setString(1,jTextField15.getText());
preparedStatement1.setString(2, jTextField1.getText());
preparedStatement1.setDate(3, start);
preparedStatement1.setDate(4, end);
preparedStatement1.setInt(5, Integer.parseInt(jTextField6.getText()) );
preparedStatement1.setInt(6,Integer.parseInt(jTextField14.getText()) );
preparedStatement1.setInt(7, Integer.parseInt(jTextField7.getText()));
preparedStatement1.setInt(8, Integer.parseInt(jTextField8.getText()));
preparedStatement1.setInt(9, Integer.parseInt(jTextField9.getText()));
preparedStatement1.setInt(10, Integer.parseInt(jTextField11.getText()));
preparedStatement1.setInt(11, Integer.parseInt(jTextField10.getText()));
preparedStatement1.setInt(12, Integer.parseInt(jTextField20.getText()));
preparedStatement1.executeUpdate();
but it has this error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'salary,private salary, food salary, other salary, bime salary, number) values ('' at line 1
What is the problem?
You really shouldn't have spaces in the field name. Try surrounding it with ``
Column names with spaces in them are a very bad idea.
If you must have them, surround them with backticks:
`private salary`
You missed ) in the last line of your SQL query so it should be:
+ " values (? ,?, ? , ?, ?, ?, ?, ?, ?, ?, ?, ? )";
Maybe you can try this:
https://github.com/stuparmihailo/util4j/releases/tag/v1.0
It's some simple project and has nice way for creating statements:
String query = "INSERT INTO table VALUES (?,?,?,?,?,?,?)";
PreparedStatement stmt = con.prepareStatement(query);
StatementUtil.fill(stmt, 45, "text", 2, null, new Date(), false, 3.5);
You should replace private salary with private_salary and keep working with acceptable column name conventions.
column or table names should not have spaces. Join them by underscore. and make them upper case... these are not rules but accepted ways of working with DB objects. If names cannot be changed in the DB and you are stuck with something like some salary, then some salary should help.
mehdi;
I think what you have to do is all of this:
change names of
space-named columns (private salary,
food salary, other salary, bime
salary) either by replacing spaces by underscores
(recommended by naming conventions) or by
surrounding names with grave accent char:
`box salary`, `private salary`, `food salary`, `other salary`, `bime
salary`
Fix this line adding final parentheses
+ "values (? ,?, ? , ?, ?, ?, ?, ?, ?, ?, ?, ?");
it must say:
+ "values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?);");
Finally I'd recommend to take out prepareStatement argument to a String or StringBuffer variable, say "sqlString" or something, so you can manipulate it more transparently. Something like this:
String sqlString = "";
sqlString += " insert into sportmangg";
sqlString += " (customer_code, sportman_code, start, finish,";
sqlString += " salary, amount, box_salary, private_salary,";
sqlString += " food_salary, other_salary, bime_salary, number)";
sqlString += " values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?);";
preparedStatement1 = connection.prepareStatement(sqlString);
(or if you use StringBuffer use append method)
