# Tests for the MINUTE() function

#

# The Drizzle MINUTE() function differs from the MySQL MINUTE()

# function in these ways:

#

#  * Does not accept invalid parameters.  This results in an error

#    in Drizzle.

#

# MINUTE() on a NULL should produce

# a NULL.

SELECT MINUTE(NULL);

# 

# Test improper argument list 

#

# 1 arg is required.

--error 1064 

# Wrong parameter count...but unfortunately produces 1064 Syntax Error due to limitations of 

# the SQL parser, which considers MINUTE a keyword before being a function symbol

SELECT MINUTE();

--error 1064

# Wrong parameter count...but unfortunately produces 1064 Syntax Error due to limitations of 

# the SQL parser, which considers MINUTE a keyword before being a function symbol

SELECT MINUTE(1, 0);

# produce an error, not a NULL or anything

# else...
