# ==== Purpose ====
#
# Test that non-deterministic expressions in column default expressions invoked
# via triggers, are correctly logged with BINLOG_FORMAT=MIXED.
#
# ==== Requirements ====
#
# R1. If a statement triggers another statement which may modify a table that
# has a column with a non-deterministic DEFAULT expression, the statement
# should be logged in ROW format when BINLOG_FORMAT is MIXED.
#
# R2. If none of the triggered statements modifies a table that has a
# non-deterministic DEFAULT expression, and the triggering statement is not
# unsafe by itself, the statement should be logged in STATEMENT format when
# BINLOG_FORMAT is MIXED.
#
# R3. If a statement directly modifies a table with a column that has a
# non-deterministic DEFAULT expression, and the statement provides an
# explicit value for the column, the statement should be logged in
# STATEMENT format when BINLOG_FORMAT is MIXED.
#
# ==== Implementation ====
#
# Test firing triggers which modify tables with non-deterministic column
# defaults, and verify that they are logged in the row format.
#
# ==== References ====
#
# WL#9418: Permit default value to be a function or expression, support for LOBs
# Bug#28297486: WL#9418: ERROR AND WARNING RELATED ISSUES
