Re: Run SQL Scripts using qsys2.qcmdexc

Don,
There are two different things in play here.
QCMDEXC, the stored procedure
QCMDEXC, the scalar function.
The stored procedure came out much earlier. When you use CALL
QSYS2.QCMDEXC... you are using the stored procedure. When you use select
..., qsys2.qcmdexc(..., from... you are using the scalar function.
For a list of what level of os and ptf's needed check out:
https://www.ibm.com/support/pages/node/1119123
Basically the stored procedure was part of the base of 7.3.
Can you tell me at what 7.3 DB2 group level did the function come out by
looking at the link above?
See also: WRKPTFGRP
However, since you are only 6 months behind, and DB2 7.3 is up to level
30, I would think you should have it. I could not find a history of when
level 24 came out.
Are you sure you're ordering group ptfs also and not just the cume?

For a definitive search you could try:
select *
from qsys2.sysfuncs
where SPECIFIC_SCHEMA='QSYS2' and ROUTINE_NAME='QCMDEXC';
This is different than
select *
from qsys2.sysprocs
where SPECIFIC_SCHEMA='QSYS2' and ROUTINE_NAME='QCMDEXC';

For 7.3 documentation on the scalar function see:
https://www.ibm.com/docs/en/i/7.3?topic=services-qcmdexc-scalar-function

This works

call qsys2.qcmdexc('rmvlible msddcb');

We are on 7.3 and about 6 months behind latest PTF's

call qsys2.qcmdexc('rmvlible msddcb')
Return Code = 0
Statement ran successfully (3 ms)

Have you checked if the QCMDEXC function exists within the QSYS2 library.
May be you are not on the current PTF level or are missing some PTFs

This also fails with the same error ...

select A.*,
case
when qsys2.qcmdexc('addlible msddcb') = 1 then 'Success'
else 'Failed'
end as "Status"
from msddcb.accountsn A;

I'm not sure, but the argument to the scalar function looks like it
resolves
into two strings rather than one because of the comma. That prototypes to
a
function that does not exist. I see too many unnecessary "concats" there.
Try to rebuild the final string that becomes only one.
Maybe that's it.

I am trying to use qcmdexc in a iACS Run SQL Scripts and it is failing

If I run call qsys2.qcmdexc('addlible msddcb'); This works

If I try the following the error indicates it can not find qcmdexc in
qsys2

select A.*,
case
when QSYS2.QCMDEXC('call ' || 'PROGRAM ' || '(' || COY, AC || ')' ) =
1 then 'Success'
else 'Failed'
end as "Status"
from msddcb.accountsn A;

I have tried putting call in front but that made no difference

What am I missing ?

I copied this basically from an example I found.

The error is

select A.*, case when qsys2.qcmdexc('addlible msddcb') = 1 then 'Success'
else 'Failed' end as "Status" from msddcb.accountsn A SQL State: 42704
Vendor Code: -204 Message: [SQL0204] QCMDEXC in QSYS2 type *N not found.
Cause . . . . . : QCMDEXC in QSYS2 type *N was not found. If the member
name is *ALL, the table is not partitioned. If this is an ALTER TABLE
statement and the type is *N, a constraint or partition was not found. If
this is not an ALTER TABLE statement and the type is *N, a function,
procedure, trigger or sequence object was not found. If a function was not


found, QCMDEXC is the service program that contains the function. The
function will not be found unless the external name and usage name match
exactly. Examine the job log for a message that gives more details on
which function name is being searched for and the name that did not match.


Recovery . . . : Change the name and try the request again. If the
object is a node group, ensure that the DB2 Multisystem product is
installed on your system and create a nodegroup with the CRTNODGRP CL
command. If an external function was not found, be sure that the case of
the EXTERNAL NAME on the CREATE FUNCTION statement exactly matches the
case of the name exported by the service program. Failed statements: 1
