lines - Row Function

Other versions: 7.31 | 7.40 | 7.54

Syntax

... lines( arg ) ...

Effect

The table function lines returns the number of rows (or lines) in an internal table. The argument arg is a functional operand position that expects an internal table. The return value has the type i.

Note

The function described here is one of the functions that can be used in the obsolete extended functional operand positions, if its argument is a single data object.

Example

The number of rows in an internal table filled from a database table must match the number of rows on the database.

SELECT carrid 
       FROM scarr 
       INTO TABLE @DATA(itab). 

SELECT COUNT(*) 
       FROM scarr 
       INTO @DATA(lines). 

ASSERT lines( itab ) = lines.
