Comparison Operators

Comparison operators are available for all data types where comparison makes sense. All comparison operators are binary operators that return values of True, False, or NULL.

Syntax and Semantics

`<`	less than
`>`	greater than
`<=`	less than or equal to
`>=`	greater than or equal to
`=`	equal
`<>` or `!=`	not equal

Notes

The != operator is converted to <> in the parser stage. It is not possible to implement != and <> operators that do different things.

The comparison operators return NULL (signifying "unknown") when either operand is null.
