# csv_not_null.test - .test file for MySQL regression suite
# Purpose: To test the behavior of the CSV engine
# Bug#31473 resulted in strict enforcement of non-nullable
# columns in CSV engine.
# NOTE: Main functionality tested - NOT NULL restrictions on CSV tables
# CREATE, INSERT, and UPDATE statements
# ALTER statements in separate file due to BUG#33696
# Author pcrews
# Last modified: 2008-01-04
