Dynamic Where Clause in a Loop ??

[Former Member]

I need a dynamich where-clause in a Loop-Statement, like this:

LOOP AT gt_outtab INTO gs_outtab

WHERE ( delta IS INITIAL AND <f_per> IS INITIAL ).

gs_outtab-delta = gs_outtab-per01.

MODIFY gt_outtab FROM gs_outtab.

ENDLOOP.

First I tried this:

LOOP AT gt_outtab INTO gs_outtab

WHERE ( delta IS INITIAL AND (ls_per) IS INITIAL ).

gs_outtab-delta = gs_outtab-per01.

MODIFY gt_outtab FROM gs_outtab.

ENDLOOP.

but with both I get a syntax error.

Do you have an idea, how can I use the component I need dynamically?

thanks.

Hello Samir,

We can not specify the dynamic where clause in Loop.

IF you want to achieve for you logic,

LOOP AT gt_outtab INTO gs_outtab

WHERE delta IS INITIAL.

<b> assign f_per to <f_per>.

if f_per is initial.</b>

gs_outtab-delta = gs_outtab-per01.

MODIFY gt_outtab FROM gs_outtab.

<b>endif.</b>

ENDLOOP.

HI

GOOD

Dynamic Conditions

To specify a condition dynamically, use:

SELECT ... WHERE (<itab>) ...

where <itab> is an internal table with line type C and maximum length 72 characters. All of the conditions listed above except for selection tables, can be written into the lines of <itab>. However, you may only use literals, and not the names of data objects. The internal table can also be left empty.

If you only want to specify a part of the condition dynamically, use:

SELECT ... WHERE <cond> AND (<itab>) ...

You cannot link a static and a dynamic condition using OR.

You may only use dynamic conditions in the WHERE clause of the SELECT statement.

===============================

DATA: TAB_SPFLI TYPE TABLE OF SPFLI,

TAB_SFLIGHT TYPE SORTED TABLE OF SFLIGHT

WITH UNIQUE KEY TABLE LINE,

WA LIKE LINE OF TAB_SFLIGHT.

SELECT CARRID CONNID

INTO CORRESPONDING FIELDS OF TABLE TAB_SPFLI

FROM SPFLI

WHERE CITYFROM = 'NEW YORK'.

SELECT CARRID CONNID FLDATE

INTO CORRESPONDING FIELDS OF TABLE TAB_SFLIGHT

FROM SFLIGHT

FOR ALL ENTRIES IN TAB_SPFLI

WHERE CARRID = TAB_SPFLI-CARRID AND

CONNID = TAB_SPFLI-CONNID.

LOOP AT TAB_SFLIGHT INTO WA.

AT NEW CONNID.

WRITE: / WA-CARRID, WA-CONNID.

ENDAT.

WRITE: / WA-FLDATE.

ENDLOOP.

thanks for the answers yet.

but I think only the answer of Naimesh Patel could be useful, i'm just checking, because there seems to be a difference between an dynamic where-clause in a select and a loop statement.
