Syntax
... operand IS [NOT] INITIAL ...
Effect
This predicate expression checks whether the operand operand is initial. The expression is true, if the operand contains its type-specific initial value. Any data objects can be specified for operand. This is an extended functional operand position in which, alongside functional method calls, constructor expressions, or table expressions, certain predefined functions can also be specified.
With the addition NOT, the expression is true if the operand contains a value other than its type-specific initial value
Notes
Example
The logical expression in the IF statement is true if the internal table in the SELECT statement was filled with rows.
