oracle.javatools.db.execute
Class PlSqlWrapper

java.lang.Object
oracle.javatools.db.execute.StatementWrapper
oracle.javatools.db.execute.QueryWrapper
oracle.javatools.db.execute.PlSqlWrapper

public class PlSqlWrapper

extends QueryWrapper

Wrapper for executing a stored procedure against the database using a CallableStatement.

• IN parameters are defined through the constructor (in the same way they are for normal queries).
• OUT parameters are included by the PlSqlRunnable passed to executePlSql.

Example usage of a query String (query) that has one IN parameter (param1) and one OUT parameter.

   final PlSqlWrapper wrap = new PlSqlWrapper( db, query, param1 );
   wrap.executePlSql(
     new PlSqlRunnable()
     {
       public void prepareCall( CallableStatement cs )
       throws SQLException
       {
         cs.registerOutParameter( 2, Types.INTEGER );
       }

       public void processCall( CallableStatement cs )
       throws SQLException
       {
         final int outParam = cs.getInt(2);
         // we have our output!
       }
     } );

public void executePlSql(PlSqlWrapper.PlSqlRunnable runner)
                  throws DBException

Executes the stored procedure and processes the resulting ResultSet and CallableStatement with the given runner.

Parameters:

runner - to process the ResultSet and CallableStatement
