Ewart:
Just FYI that you might need to be careful about using Values(select...
Into). If your select statement result in more than one row, as far as
I can remember, the sql statement will failed.

Subject: RE: SQL statement not working

As many has already mentioned, host variable cannot be used in the
dynamic sql statement. I personally prefer using static SQL. It is
much easier to understand and test/debug issue.

From what I can tell, it seems like the reason that you create the
alias
is so that you can run the select statement on a specific member. If
this is the case, you could create this temporary alias in QTEMP using
static sql. See below:

* override to the desire member and library first
C eval cmdStr=
C 'OVRDBF FILE(OPBAL) ' +
C 'TOFILE(' + %trim(wlib820) + '/OPBAL) ' +
C 'MBR(' + %trim(wMbrFr) + ')'
C callp qcmdexc(cmdStr :%len(%trimr(cmdStr)))


C/exec sql
C+ drop alias qtemp/myOPBAL
C/end-exec

C/exec sql
C+ create alias qtemp/myOPBAL for OPBAL
C/end-exec

C/exec sql
C+ values(
C+ select b0bvva
C+ from qtemp/myOPBAL
C+ where
C+ b0aqcd = :hhstock and
C+ b0bycd = :witemcd and
C+ b0c8cg = :hhbrand)
C+ into :HHOPBAL
C/end-exec

C endsr

Subject: SQL statement not working

Hello All,

I am trying to use an SQL statement to get the opening & closing balance
from two separate members in a file. The statement does not seem to
work.
When it is run in interactive SQL if works fine. I know there is
something to do with ':' but i just can't seem to find the fault.

I've only pasted the code for the opening balance as the Closing balance
code is similar.
// Get Opening Balance
wsqlstm = 'DROP ALIAS ' + %trim(wlib820)+'/'+ 'OpBal'; exsr PrepSQL;
exsr ExecSQL; wsqlstm = 'CREATE ALIAS ' + %trim(wLib820)+ '/opbal FOR
'+
%trim(wLibdta) + '/'+'STVATRP'+'(' + %trim(wMbrFr) +')'; exsr
PrepSQL; exsr ExecSQL; wsqlstm = 'select b0bvva into :hhopbal from ' +

%trim(wLib820)+ '/opbal '+
' where b0aqcd = :hhstock and '+
' b0bycd = :witemcd and '+
' b0c8cg = :hhbrand';
exsr PrepSQL;
exsr ExecSQL;
-----------------

/end-free
CSR PrepSQL begsr
c/Exec SQL Prepare SqlStmt from :wsqlstm c/End-Exec
C endsr
CSR ExecSQL begsr
c/Exec SQL execute SqlStmt
c/End-Exec
C endsr

-----------------

Is the statement in bold correct ??

Thanks & best regards
Ewart
