Nested stored procedure support
DB2 now delivers nested stored procedure support that simplifies the migration of applications from other database vendors, and allows application developers to use and exploit stored procedures in a more effective way.

SQL procedures language

SQL procedure language support is now available for DB2 on Microsoft Windows, OS/2®, and Unix®, in addition to DB2 Universal Database for OS/390® and AS/400®. It supports building DB2 stored procedures that employ SQL in a manner consistent with the Persistent Stored Module definition of the ANSI SQL99 standard.
