# Tests for the QUARTER() function

#

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

# function in these ways:

#

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

#    in Drizzle.

#

# QUARTER() on a NULL should produce

# a NULL.

SELECT QUARTER(NULL);

# 

# Test improper argument list 

#

# 1 arg is required.

--error ER_PARSE_ERROR 

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

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

SELECT QUARTER();

--error ER_PARSE_ERROR

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

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

# produce an error, not a NULL or anything
