Class PlSqlWrapper

java.lang.Object

      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!
       }
     } );

query - the pl/sql to execute

params - any IN parameters for the pl/sql

Method Detail

createStatment

protected java.sql.Statement createStatment()
                                     throws java.sql.SQLException

Description copied from class: StatementWrapper

Creates the Statement object to use. By default this creates a simple Statement, subclasses can override to create a Prepared or Callable statement.

Overrides:

createStatment in class QueryWrapper

Throws:

java.sql.SQLException

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

Throws:

DBException - for any errors
