# Purpose: #
|
|
# Auxiliary script, only useful when sourced by inc/partition_check.inc. #
|
|
# The trigger uses new values (--> event UPDATE, INSERT only) #
|
|
# #
|
|
# 1. Create a trigger #
|
|
# 2. Execute a statement, which activates the trigger #
|
|
# 3. Check the results of the trigger activity #
|
|
# 4. Revert the modifications #
|
