ISSUE: 5073

TITLE: Table aliasing is unnecessary required when doing UPDATE ... RETURNING RDB$ pseudo-columns
|
|
DESCRIPTION:
|
|
NOTES:
|
|
After fix #6815 execution plan contains 'Local_Table' (FB 5.0+) for DML with RETURNING clauses:
|
|
"When such a statement is executed, Firebird should execute the statement to completion
|
|
and collect all requested data in a type of temporary table, once execution is complete,
|
|
fetches are done against this temporary table"
