APAR status

  • Closed as program error.

Error description

  • If an application has created a declared global temporary table
    (DGTT) or has instantiated a created GLOBAL temporary table
    using the ON COMMIT DELETE ROWS option (default), then issuing a
    compiled compound SQL statement or a PL/SQL anonymous block
    might delete all the rows of those tables in that connection,
    even though no commit has been issued.
    

Local fix

  • Possible ways to avoid this issue include:
    1. Using the ON COMMIT PRESERVE ROWS option for global temporary
    tables and explicitly delete rows from those tables rather than
    relying on ON COMMIT DELETE rows.
    2. Reworking the compound SQL (or PL/SQL Anonymous block)
    as a procedure that is called.
