Modify database tabel from internal table

[Former Member]

Hi,

I want to modify a z-table from an internal table. However the z-table has fewer columns hence I only want to write selected columns from my internal table.

I tried:

LOOP AT IT_RECORD INTO WA_RECORD.

MODIFY ZTEST FROM WA_RECORD.

ENDLOOP.

This does not work the way I want because it writes to the wrong columns. Any suggestions?

Hi,

use move-corresponding

You can, but willl not suggest you to modify any standard DB table. You custom table is ok.

But remember to pass all the key fields while modifying.

DATA: wa_ztest TYPE ztest.

LOOP AT IT_RECORD INTO WA_RECORD.
  MOVE-CORRESPONDING wa_record TO wa_ztest.
MODIFY ZTEST FROM wa_ztest.
ENDLOOP.

What about this:

LOOP AT it_record INTO wa_record.
  UPDATE ztest
    SET zf1 = wa_record-f1
        zf2 = wa_record-f2
*       etc.
    WHERE key1 = wa_record-key1
      AND key2 = wa_record-key2.
*     AND etc.
ENDLOOP.

I can't use update if the table is empty...

If the table is empty, it doesn't go through the loop.

Hi,

I have written a small programm which reads from the local csv

file and writes it first in the internal and then in the database table. I have not tried to write the record directly in the database table because in the db table i have used float datatypes and 'GUI_UPLOAD' function return only string.

The colums in the CSV file should not be separated through ; or , but should separated through . It can be achieved through macros or simply Replace function in most of the editors. so here is the Code. I hope it will be helpful.
