# Tests for the YEAR() function

#

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

# function in these ways:

#

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

#    in Drizzle.

#

# YEAR() on a NULL should produce

# a NULL.

SELECT YEAR(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 YEAR a keyword before being a function symbol

SELECT YEAR();

--error ER_PARSE_ERROR

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