In Spring JDBC, how to set RESULT SET HOLDABILITY on statements?

Question

I would like to prepare statements with resultSetHoldability parameter set to ResultSet.CLOSE_CURSORS_AT_COMMIT:

PreparedStatement stmnt = conn.prepareStatement(sql, resultSetType, resultSetConcurrency,
    ResultSet.CLOSE_CURSORS_AT_COMMIT)

...and the same for prepareCall. I am currently using Spring's JdbcTemplate and SimpleJdbcCall, because it has that convenient declareParameters() and execute(Map paramValues) methods.

So what would be the simplest way to set resultSetHoldability?

Answer 1

The easiest way is to use one of the various query methods on JdbcTemplate which take a PreparedStatementCreator object as their first argument.

You give it a PreparedStatementCreator object which constructs the PreparedStatement from the supplied Connection, and returns that, e.g.

PrepatedStatementCreator psc = new PrepatedStatementCreator() {
   public PreparedStatement createPreparedStatement(Connection conn) {
      return conn.prepareStatement(sql, resultSetType, resultSetConcurrency, 
          resultSetHoldability);
   }
}

jdbcTemplate.query(psc, ...);

Answer 2

You could use the following method.

   execute(ConnectionCallback action)

The connectioncallback gives you access to the connection object, which has a setHoldability method
