Comparison CCL Operators

Comparison CCL operators conducts a comparison of TRUE, FALSE, or NULL.

Comparison operators compare one expression to another. The result of such a comparison can be TRUE, FALSE, or NULL. Comparison operators use the following syntax:


expression1 comparison_operator expression2

where expression1 and expression2 are a pair of numeric, Boolean, String, or Timestamp expressions and comparison_operator is one of the operators described in the following table:

Operator

Purpose

=

Equality, which can also be used in a multi-equality expression, such as A=B=C.

!=, <>

Inequality.

>, <

Greater-than and less-than .

>=, <=

Greater-than-or-equal-to and less-than-or-equal-to.

When comparing numeric expressions, Sybase uses numeric precedence to determine whether the condition compares INTEGER or FLOAT values.
