# Tests for the SECOND() function

#

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

# function in these ways:

#

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

#    in Drizzle.

#

# SECOND() on a NULL should produce

# a NULL.

SELECT SECOND(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 SECOND a keyword before being a function symbol

SELECT SECOND();

--error ER_PARSE_ERROR

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

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