Truth Value Conditions

The truth value of a condition is either TRUE or FALSE.

The syntax for truth value conditions is:

ISNOT ] truth-value

Without the NOT keyword, the condition is TRUE if the condition evaluates to the supplied truth-value, which must be one of TRUE, FALSE, or UNKNOWN. Otherwise, the value is FALSE. The NOT keyword reverses the meaning of the condition but leaves UNKNOWN unchanged.

Truth-valued conditions are supported by Sybase IQ only.
