Named quaries

Question

Hi all,
I want to use named query offered by toplink but when I execute my java code I have this error:
EXCEPTION [TOPLINK-4002] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.DatabaseException
EXCEPTION DESCRIPTION: java.sql.SQLException: ORA-01008: Toutes les variables ne sont pas liées
Below the java source generated by toplink:
//Named Queries
//Named Query -- FindCPSById
ReadAllQuery namedQuery0 = new ReadAllQuery(riad.rm.marche.beans.consultation.CCps.class);
     namedQuery0.setSQLString("select * from C_CPS where ID_CPS = ?1");
     namedQuery0.setName("FindCPSById");
     namedQuery0.setCascadePolicy(1);
     namedQuery0.setQueryTimeout(0);
     namedQuery0.setShouldUseWrapperPolicy(false);
     namedQuery0.setShouldBindAllParameters(true);
     namedQuery0.setShouldCacheStatement(false);
     namedQuery0.setSessionName("security");
     namedQuery0.setShouldMaintainCache(true);
     namedQuery0.setShouldRefreshIdentityMapResult(false);
     namedQuery0.setLockMode((short)0);
     namedQuery0.addArgument("1", java.lang.Double.class);
     descriptor.getQueryManager().addQuery("FindCPSById", namedQuery0);
And my code source test :
Vector vecParam = new Vector();
Double id = new Double(8);
vecParam.addElement(id);
Collection cCPS =Collection cCPS = (Collection) session.executeQuery("FindCPSById",CCps.class,vecParam);
Thanks,

Hello dadsi,
TopLink does not use the ?x parameter delimiter in custom sql (unlike ejbql).
Instead we use #<name> where name is the name of the argument (addArgument()) added to the query.
So your sql string would look like "select * from c_cps where id_cps=#1" Note that you can use meaningful names, rather than just numbers for your arguments.
I hope this helps,
Christian
