# ==== Purpose ====
#
# Test errors for Unsafe statement generated inside DEFAULT expression
#
# ==== Requirements ====
#
# R1. `ALTER TABLE` with a non-deterministic function as a `DEFAULT` expression
# for an added column should always fail for `BINLOG_FORMAT=MIXED/ROW` with
# an unsafe statment error - ER_BINLOG_UNSAFE_SYSTEM_FUNCTION
#
# R2. `ALTER TABLE` with a deterministic function as a `DEFAULT` expression for
# an added column should always succeed with `BINLOG_FORMAT=MIXED/ROW`.
#
# ==== Implementation ====
#
# Test `ALTER TABLE ... ADD COLUMN ... DEFAULT` statement with both a
# deterministic and non-deterministic function as the `DEFAULT` expression
#
# ==== References ====
# WL#9418 Permit default value to be a function or expression, support for LOBs
# BUG#28799939 DISALLOW ALTER TABLE ADD COLUMN WITH NONDETERMINISTIC DEFAULT, IF BINLOG ENABLED
