How to handle nonJDBC arguments for Oracle Stored Procedures
The standard way of handling a Stored Procedure is to build an instance of oracle.toplink.queryframework.StoredProcedureCall. However, the arguments must be compatible with the JDBC specification.
To handle nonJDBC arguments (e.g. BOOLEAN, PLS_INTEGER, PL/SQL record, etc.) a new sub-class has been created: oracle.toplink.platform.database.oracle.PLSQLStoredProcedureCall:
For the target procedure:
procedure bool_test(x IN BOOLEAN)
the TopLink code would be:
import oracle.toplink.internal.helper.NonSynchronizedVector;
import oracle.toplink.platform.database.oracle.PLSQLStoredProcedureCall;
import static oracle.toplink.platform.database.oracle.OraclePLSQLTypes.PLSQLBoolean;
public class NonJDBCTestSuite {
public static void main(String args[]) {
PLSQLStoredProcedureCall call = new PLSQLStoredProcedureCall();
call.setProcedureName("bool_in_test");
call.addNamedArgument("X", PLSQLBoolean);
DataModifyQuery query = new DataModifyQuery();
query.addArgument("X");
query.setCall(call);
Vector queryArgs = new NonSynchronizedVector();
queryArgs.add(Integer.valueOf(1));
s.executeQuery(query, queryArgs);
}
}
