net.sf.jkniv.whinstone.jdbc.dialect.DB2EnableMYSDialect

All Implemented Interfaces:

SqlDialect

public class DB2EnableMYSDialect
extends AnsiDialect

Dialect to DB2 with compatibility features for MySQL applications.

Limit clause: select name from author LIMIT 1 OFFSET 2

• Supports limits? true
• Supports limit off set? true
• Supports rownum? false

The DB2_COMPATIBILITY_VECTOR registry variable enables one or more DB2® compatibility features. These features ease the task of migrating applications that were written for relational database products other than the DB2 product to DB2 Version 9.5 or later.

This registry variable is supported on Linux, UNIX, and Windows operating systems. You can enable individual DB2 compatibility features by specify a hexadecimal value for the registry variable. Each bit in the variable value enables a different feature. Values are as follows:

   NULL (default)
   0000 - FFFF
   ORA, to take full advantage of the DB2 compatibility features for Oracle applications
   SYB, to take full advantage of the DB2 compatibility features for Sybase applications
   MYS, to take full advantage of the DB2 compatibility features for MySQL applications
