# Tests for the WEEKDAY() function
#
# The Drizzle WEEKDAY() function differs from the MySQL WEEKDAY()
# function in these ways:
#
# * Does not accept invalid parameters. This results in an error
# in Drizzle.
#
# WEEKDAY() on a NULL should produce
# a NULL.
SELECT WEEKDAY(NULL);
#
# Test improper argument list
#
# 1 arg is required.
--error ER_WRONG_PARAMCOUNT_TO_FUNCTION # Wrong parameter count...
SELECT WEEKDAY();
--error ER_WRONG_PARAMCOUNT_TO_FUNCTION # Wrong parameter count...
SELECT WEEKDAY(1, 0);
#
# Test invalid dates passed to WEEKDAY
# produce an error, not a NULL or anything
# else...
