CL_GUI_FRONTEND_SERVICES in select loop

Former Member — Fri, 28 Jul 2006 08:51:59 GMT

Hi all,

I have a problem using CL_GUI_FRONTEND_SERVICES=>FILE_EXIST within a select loop. I want to loop through a databasetable with filenames and if the file exists, do some stuff with it. The method works good, but when the loop is executed and the next SELECT is executed I get a short dump:

DBIF_RSQL_INVALID_CURSOR

CX_SY_OPEN_SQL_DB

Invalid interruption of a database selection.

This is my code:

SELECT file FROM files INTO l_file.

WHERE EXTID = p_extid AND UNAME = sy-uname.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_EXIST

EXPORTING

FILE = l_strfloc

RECEIVING

RESULT = l_result.

ENDSELECT.

Better select data into table.

then use

LOOP AT ITAB.

CALL GUI_FRONT END SERVICES.

ENDLOOP.

OTHER WISE......you cannot interfere the Prsentation (Desktop) Servier Logic with the DATA BASE LOGIC ....SELECT ENDSELECT.
