A boolean search condition used to evaluate whether a statement or statements embedded within an IF, CASE, REPEAT, or WHILE clause should be performed.

Arithmetic expressions, logical expressions, UDT expressions, and status variables can all be specified as conditional expressions.

You cannot use IN and NOT IN operators if the conditional list contains any local variables, parameters, or cursor correlation names.

OUT parameters and subqueries are not allowed in conditional_expression.
