How to update database table !!!

[Former Member]

hi all,

Please advice how to update database table with certain cndition needs to be checked.

Please consider below scenario.

have used enqueu and dequeue function to lock entries  and also i have used BAPI so considering that return parameter . i want to update table

/tdk/st0027.

1. I want to update database table

2. there are certain condition needs to be checked like ,

   loop at it_final into wa_final.

th_return-type = 'S'.

*********************************************************************

           if th_final-vbeln = /tdk/st0027-vbeln and

              th_final-posnr = /tdk/st0027-posnr and

              th_final-etenr = /tdk/st0027-sdslno.

above condition which i need to check .and need to append below system fields need to be appended in table.

          th_final-prstsind = '20'.

          th_final-chgdate  = g_date.

          th_final-chgtime  = g_uzeit.

          th_final-chgprog  = g_cprog.

          th_final-chguser  = g_uname.

          append th_final to td_final.

          update /tdk/st0027 FROM th_final.

          endif.

endloop.

but i am getting error saying that  "The type od database table and work area (TH_FINAL)  are not unicode convertible"?

I am not able to understandwhat would be the solution for this ?

Thanks and regards,

Hi,

The work area is not type compatible with the DB.

Check how  you have declared the work area TH_FINAL.

It should be DATA: work area  TYPE database table.

Please compare structure of typ_final with database table /tdk/st00027. These both are different. Please create a local internal table of same type as database table. append data into that table and update

Hi but i want to update only some of fields of them .. have declared another structure with same fields still i am getting same error. ??

hi,

plz check the data type of your inter table th_final.

your  table type must be same .

i think the structure of both table is not same. first declare a local internal table as same as structure of that db table. then move corresponding value of th_final to that local internal table. then, update it.

The error occurs in the UPDATE statement included in the code. In this statement it is seen that there is a mismatch of structure defined for the DDIC table /tdk/st0027 and that of your work area th_final.

try to create a structure w.r.t the DDIC table.

Eg: DATA: wa_temp TYPE /tdk/st0027.

MOVE-CORRESPONDING th_final TO wa_temp.

Then try to UPDATE using the temporary work area i.e wa_temp which has structure similar to that of the database table.

Either use a structure identical to database (and initially filled with current values of every field from database, else many fields will get initial value) or use a LOOP and a SELECT SET field = value WHERE statement.
