can we use cl programming to update or delete physical files

Answer / anish
Although there are no keywords to update or insert or
delete records in a CL program, we can do the same with the
help of a 'RUNSQLSTM' statement. With this command we can
runa query directly from the CL program and do an
insert/update/delete without calling an RPG program.
Plzz let me know if my understanding is corerct.

Answer / saravan
We can clear file using CLRPFM command.
If we want delete PF we can use DLTF command.
But before delete any PF first of all we need to
delete all the LFs related in that PF.(DSPDBR=Display Data
Base Relations,we can get all LFs relating to that PF)You
must give the correct Library name for all the commands
above.
For UPDATE, DELETE & INSERT, use RUNSQL command.
Ex: RUNSQL (UPDATE LIBR/FILE SET FLD = 'XXX'
WHERE CONDITION)
Note: RMVM is to delete/remove a member from a file. But
not to delet a file completely.

No, you can access the records using the CL program but
can't perform any operation other then reading the records.

Answer / chirag
Hi,
First you need to create a TXT source in which you need to
provie the update command.
Next in CL program you should use the command RUNSQLSTM on
this source(TXT).
So whenever you have to change another record you need to
simply change and save the TXT source.
Examply:
Data on file, PF1:
FLD1 FLD2 FLD3
000001 001 AAA BBB
000002 002 BBB CCC
000003 003 CCC DDD
000004 004 XXX ZZZ
Member1, Name: PGM1 , Type: TXT
UPDATE PF1 SET FLD3 = 'CHG' WHERE FLD1 = '004';
Member2, Name: PGM2 , Type: TXT
PGM
RUNSQLSTM SRCFILE(LIB1/SRCFILE) SRCMBR(PGM1) +
COMMIT(*NONE)
ENDPGM
Compile the PGM2 and call it.
Now Result for data on PF1
FLD1 FLD2 FLD3
000001 001 AAA BBB
000002 002 BBB CCC
000003 003 CCC DDD
000004 004 XXX CHG
