V$FLASHBACK_TXN_MODS

V$FLASHBACK_TXN_MODS displays the individual modifications of all the transactions in memory.

This view is relevant AFTER a compensating transaction has been started through the DBMS_FLASHBACK.TRANSACTION_BACKOUT() set of functions, and is no longer relevant once the compensating transaction is either committed or rolled back. It also provides a tabular representation of the undo SQL that is not available through the CLOB XML construct in the DBA_FLASHBACK_TXN_REPORT view.

Column Datatype Description
COMPENSATING_XID RAW(8) Transaction ID of the compensating transaction
COMPENSATING_TXN_NAME VARCHAR2(255) Name of the compensating transaction
XID RAW(8) Transaction ID of a relevant transaction found in memory
TXN_NAME VARCHAR2(255) Name of the transaction with XID as the transaction ID; NULL if none
PARENT_XID RAW(8) Parent transaction ID (for a PDML transaction)
INTERESTING NUMBER If the transaction is in the transaction dependency graph
ORIGINAL NUMBER If the transaction is part of the input set provided
BACKOUT_SEQ NUMBER Order in which the transaction has been backed out
UNDO_SQL VARCHAR2(4000) Undo SQL for the modification
UNDO_SQL_SQN NUMBER Order in which the given SQL has been executed to back out this transaction
UNDO_SQL_SUB_SQN NUMBER If the undo SQL is greater than 4000 bytes, then a sequence number, starting from 1, of a 4000-byte division of the undo SQL
BACKOUT_SQL_ID NUMBER SQL ID of the undo SQL (used only for this compensating transaction)
OPERATION VARCHAR2(30) Operation (such as insert/update/delete) performed by the forward-going operation
BACKEDOUT NUMBER Indicates whether the transaction has been backed out as of now
