RE: Calling a SQL script with parameters from CL program

Better yet, you can pass parameters to SEQUEL's RUNSCRIPT command.

SEQUEL has recently added CL style coding capability, including IF-THEN-ELSE
logic.

You can't pass parameters to RUNSQLSTM. You CAN pass "parameters" to a
QM query, which I prefer for this kind of thing. It is possible to
execute multiple QM queries using a QM procedure, by the way, but
passing parameters to that is not as easy.

Also, you cannot run a SELECT in RUNSQLSTM.

Do you have STRSQL on your machine? Then you also have STRQM (Start
Query Manager). This is a front end to QM (Query Management) queries and
forms. A query and form together are almost equivalent to a Query/400
query definition.

Or you can CRTSRCPF YOURLIB/QQMQRYSRC RCDLEN(91)

Yes, 91 - for reasons not known to me.

Create a member there and put this statement in it. This contains
substitution variables - similar to merge variables in Query/400. The
variables are &QT - will be a quote mark - and &DATE - your date.

SELECT FLD1,FLD2,FLD3,FLD4
FROM MYFILE
WHERE FLD1 = &QT&DATE&QT

Then use CRTQMQRY to create the QM query, say YOURLIB/YOURQMQRY.

To execute the select, do something like this -

STRQMQRY YOURLIB/YOURQMQRY SETVAR((QT '''') (DATE '20080228'))

You can also have an OUTFILE in your STRQMQRY - in RUNSQLSTM you need a
CREATE TABLE based on a SELECT, perhaps. Or INSERT INTO with a subselect.

Anyhow, create all the QM queries you need. If you create them in STRQM,
you will have to get privileges there to do more than SELECT statements.
If you do it from source, no limitations. Also, take a look at WRKQMQRY.

In your CL, use all the STRQMQRY's you need. And you might even front
the CL with a command, to enter the date or other values you need.

Dear All



I have a small question...



I have some SQL statements that I will put in a SQL Script, and I will run

these script from CL program (using RUNSQLSTM command) ...

If I have something like this:

SELECT FLD1,FLD2,FLD3,FLD4

FROM MYFILE

WHERE FLD1 = '20080228';



Can I pass parameters from my CL program to a script in order to avoid

hard coding the date '20100228' ?

If yes, how can I do this in both CL & script ?



Thanks in advance for your help
