#-----------------------------------------------------------------------------
# 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
