Birgitta,

I'll be giving this a try shortly and will report back with my results.
Thanks!

NOT VALUES but VALUES .... INTO which is a completely different statement.

Just have a look at my example, where I converted your SELECT INTO
statement into a VALUES INTO statement

Vern/Birgitta,

I just took a quick look in the SQL reference. It says that the VALUES
statement cannot be dynamically prepared, which is what is happening in
this case. Is that true?

Hi Bill

VALUES is a very useful statement - there is more detail in the SQL
reference, that is not practical to repeat all here - so I heartily
recommend looking it up.

A similar statement is SET, as I recall - check me by looking at the
reference - I've used it in an embedded SQL RPG program to get a
scan/replace before IBM provided %scanrpl - it requires that whatever
function you use returns a single value. Here's an idea of it - it
does use a host variable -

set :currtimestamp = current timestamp;

That gets microseconds, while I think RPG returned only milliseconds
(at one time, at least).

So there are lots of things that come from SQL that you can use to set
variables in RPG directly.

Birgitta,

Thanks for the info. So "VALUES" is a separate SQL statement then? I
don't need an "INSERT INTO" or anything like that before it?

SELECT INTO cannot be used in composition with dynamic SQL.
You either need a cursor, performing a PREPARE, DECLARE, OPEN, FETCH
and CLOSE statement.
Or VALUES INTO which is supported in conjunction with dynamic SQL

MySQLTEXT = 'Values(Select RRN(a), ' + %Trim(Field_Name) +
' From ' + %Trim(Library_Name) + '/' +
%Trim(File_Name) +
' a Where RRN(a) = 1) +
' into ?, ?);

Exec SQL Prepare DynSQL From :MySQLText;

Exec SQL Execute DynSQL using :HostVarRRN, :HostVarField;

Betreff: Embedded SQL question

Hello all,

I'm trying to use dynamic embedded SQL to retrieve a value in a
program.
I was originally trying to use host variables for the needed data
but then I found out that you can't use host variables in dynamic
SQL and that you
have to use parameter markers instead. So here's what I have:

MySQLText = 'Select rrn(a), a.' + %Trim(Field_Name) +
' Into ?,?' + ' From ' +
%Trim(Library_Name) + '/' + %Trim(File_Name) +
' a where rrn(a) = 1';

exec sql
SET OPTION
commit=*none,
datfmt=*iso;

exec sql prepare selectRecord from :MySQLText; exec sql execute
selectRecord using :rrn,:OldCompany;

When I run the program in debug, the MySQLText field looks like this:

Select rrn(a), a.CONO15 Into ?,? From COPYAULT2/INP15 a wher e
rrn(a) = 1

and I get the following errors:

Token ? was not valid. Valid tokens: : <IDENTIFIER>.
Prepared statement SELECTRECORD not found.


I'm stumped as to what to do from here. This SQL statement should
yield
one record (and does when run interactively) and the thing I'm
trying to grab is the value in :OldCompany.

Any help would be MOST appreciated. Thanks!

Bill
