# 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
