Subject weird problem creating sql suery string from criteria
Date Wed, 28 Jun 2006 00:54:35 GMT
Hi

 

I have a problem where If I set criteria add a select column, 95% of the
time getting a SQL query string from the criteria works. But
occasionally it doesn't create a calid SQL string.

 

This is the code

 

            // create the count criteria

            Criteria rarCriteria = new Criteria();

            rarCriteria.addSelectColumn("COUNT(*)");

            getReturnAuthorisationRequestSearchCriteria(rarCriteria);

            String query = ReturnAuthorisationRequestPeer

                        .createQueryString(rarCriteria);

            List list = ReturnAuthorisationRequestPeer.executeQuery(

 
ReturnAuthorisationRequestPeer.createQueryString(rarCriteria),

                        ReturnAuthorisationRequestPeer.DATABASE_NAME);

            return ((Record) list.get(0)).getValue(1).asInt();

 

 

/*

getReturnAuthorisationRequestSearchCriteria(rarCriteria); just adds the
criteria using the standard Torque methods. add, some criterion and's,
and depending on the conditions a join.

*/

 

Now when I run this once, with all the same settings it will work.
Occasionally it will throw a SQL syntax error in my sql.

 

All the conditions fo creating the criteria will be the same as the
previous (succesful) criteria build.

 

When it fails,
ReturnAuthorisationRequestPeer.createQueryString(rarCriteria) create a
string "Select COUNT(*) FROM" with nothin else. Obvioulsy when it works
it produces the complete SQL string.

 

Why does Torque selectively create the SQL differently? Is this a bug?
Is there any way to guarantee that this will work every time. Otherwise
I will have ot manually build an SQL string.

 

Any help would be appreciated

 

Regards

 

Steve
