tests/t/month.test

# Tests for the MONTH() function

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

# function in these ways:

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

# in Drizzle.

# MONTH() on a NULL should produce

# a NULL.

SELECT MONTH(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 MONTH a keyword before being a function symbol

SELECT MONTH();

--error 1064

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

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

SELECT MONTH(1, 0);

# Test invalid dates passed to MONTH

# produce an error, not a NULL or anything

# else...

SELECT MONTH("1900-02-29"); # Not a leap MONTH since not divisible evenly by 400...

--error 1686

SELECT MONTH('1976-15-15'); # No 15th month!

# A good date, which should output 1

SELECT MONTH("2009-01-12");

# A good date, which should output 1999 - Test of 1 digit MONTH conversion...

SELECT MONTH("99-1-31");

# A good date, which should output 9

SELECT MONTH("0001-09-30");

# A good date, which should output 12

SELECT MONTH("9999-12-31");

# A good date in the common USA format, should output 7

SELECT MONTH('07/31/2009');

# Tests for alternate DATETIME syntaxes

# in string and numeric formats. All should

# return 9.
