log_exp - IS INITIAL

Other versions: 7.31 | 7.40 | 7.54

Syntax

... operand IS [NOT] INITIAL ...

Effect

This logical expression checks whether the operand operand is initial. The expression is true, if the operand contains its type-specific initial value. For operand, you can specify data objects, built-in functions and functional methods. The latter use the return value as the operand.

With the addition NOT, the expression is true if the operand contains a value other than its type-specific initial value

Example

The logical expression in the IF statement is true if the internal table in the SELECT statement was filled with rows.

DATA spfli_tab TYPE TABLE OF spfli.
...
CLEAR spfli_tab.
SELECT *
       FROM spfli
       INTO TABLE spfli_tab
       WHERE ...

IF spfli_tab IS NOT INITIAL.
  ...
ENDIF.
