15. 1. 1. Comparison Functions and Operators

Comparison operations result in a value of 1 (TRUE), 0 (FALSE), or NULL.

Comparison Functions and Operators work for both numbers and strings.

Strings are converted to numbers and numbers to strings as necessary.

By default, string comparisons are not case sensitive and use the current character set.

<=>	NULL-safe equal to operator
=	Equal operator

>	Greater than operator
GREATEST()	Return the largest argument
IN	Check whether a value is within a set of values
INTERVAL()	Return the index of the argument that is less than the first argument
IS NULL	NULL value test
IS	Test a value against a boolean
ISNULL()	Test whether the argument is NULL
LEAST()	Return the smallest argument
<=	Less than or equal operator
