RE: SQLRPGLE Update Dynamic Filename using WHERE CURRENT OF

The UPDATE should reference the table you want to update.

For example, here's my RDi snippet for updating a cursor:
EXEC SQL
update ${Library}/${File}
set COLUMN = :VARIABLE
where current of ${Cursor};

(Where ${} and " COLUMN = :VARIABLE" are placeholders to be filled in when inserting the snippet.)

Subject: SQLRPGLE Update Dynamic Filename using WHERE CURRENT OF

HI All,

Need some help with this as I cannot find an example.

I have a filename that is input as a parm.
I prepare the sql statement with the variable filename, then declare, open, fetch/update loop and close.
Now when I update the current record all samples I have seen are using a hard coded filename.
I believe I could get around with a sql execute immediate but would like to stick with WHERE CURRENT OF.

Any help appreciated.
Here are the relevant bits....It's the 'Update @FileName' below that throws me off.

DCL-S SelectSQL Like(StdLTxtVar)
Inz('Select keyValues from &1 FOR UPDATE OF TOKEN');

// Replace marker with file name
SelectSQL = %ScanRpl('&1' :@FileName :SelectSQL);

exec sql
Prepare S1 from :SelectSQL;
exec sql
declare C1 cursor for S1;
exec sql
open C1;
exec sql
fetch next from C1 into :KeyValues;

WrkToken = xmlTransaction(keyValues :Mode :@LoadName :groupID);

exec sql
Update @FileName
Set Token = :WrkToken
WHERE CURRENT OF C1;

Thanks in advance...
- Steve
