# BUG#19958: RBR idempotency issue for UPDATE and DELETE
|
|
|
|
# Statement-based and row-based replication have different behaviour
|
|
# when updating a row with an explicit WHERE-clause that matches
|
|
# exactly one row (or no row at all). For statement-based replication,
|
|
# the statement is idempotent since the first time it is executed, it
|
|
# will update exactly one row, and the second time it will not update
|
|
# any row at all. This was not the case for row-based replication, so
|
|
# we test under both row-based and statement-based replication both
|
|
# for tables with and without primary keys.
