If most of the dynamic statements in an application are likely to be executed many times in the course of a session, proceed as follows:
Set the connection property DYNAMIC_PREPARE to "true."
To return PreparedStatement objects containing precompiled statements, use Connection.prepareStatement in the standard way:
PreparedStatement ps_precomp = Connection.prepareStatement(sql_string);
To return PreparedStatement objects containing uncompiled statements, you can use either Connection.prepareCall (see Prepared statements in portable applications) or SybConnection.prepareStatement, with dynamic set to “false”:
PreparedStatement ps_uncomp = (SybConnection)conn.prepareStatement(sql_string, false);
PreparedStatement ps_uncomp = Connection.prepareCall(sql_string);
