Rules and Guidelines for IBM DB2

Rules and Guidelines for IBM DB2

Certain rules and guidelines apply for pushdown optimization to an IBM DB2 database.
Use the following rules and guidelines for pushdown optimization to an IBM DB2 database:
  • When you apply pushdown optimization to an IBM DB2 database, a session that requires type casting can fail. The session fails if the casting is from float or double to string, or if it requires a type of casting that IBM DB2 databases disallow.
  • To push TO_DATE() and TO_CHAR() functions to an IBM DB2 database, you must use the following formats:
    • YYYY-MM-DD HH24:MI:SS
    • YYYY-MM-DD-HH24.MI.SS.US
    • YYYY-MM-DD-HH24.MI.SS.MS
    • YYYY-MM-DD-HH24.MI.SS
