Need Uppercase Update functionality from PB

I have a PowerBuilder application that I need to run against a Sybase ASE 12 database which is configured to be case sensitive and requires all SQL to be uppercase.  I converted all of the datawindow retrieve and embedded SQL to uppercase and it all works, but the datawindow updates did not work.  I exported the datawindows and changed all of the update DB names to uppercase but it still is working for the updates.
Does anyone have any ideas of anything that I could try??

There are two points I would try:

1) try to re-select updatable table in update properties of datawindow object

2) check sqlsyntax argument in SQLPreview for what is send to ASE.

Or run your app with /PBDEBUG and it will output a debug file with all the code and sql sent to the database.

You saud all SQL needs to be uppercase. You shouldn't have to worry about the case of the SQL syntax. You meant the column names? Or do you mean you want to keep the data in all upper case?

Quick and simple...

Follow jkotek's advice, but add this code (can be done in a DW control ancestor if you like) to the SQLPreview event:

SetSQLPreview( Upper( SQLSyntax ) )
Return 0

This makes all SQL uppercase before it is sent to the DB.

Good luck

Any modifications in a PB DataWindow (even if it is changing the case of the source) requires to re-specify the Update on the DataWindow. Did you do this ? If yes, what is the message that you are getting when you run the PB Application ?

In the dw syntax there is a statement like  update="plant" ( in this case from a pbselect, or graphics mode ) it tells pb the name of the table to update.  That is what needs to be in upper case.
You can get at this without running thru the syntax of the dw ( not the sql )
by using the dw property


Datawindow.Table.UpdateTable      
as in

ls_table =  dw_1.Object.DataWindow.Table.UpdateTable      

which you might follow with

dw_1.Object.DataWindow.Table.UpdateTable      = Upper( ls_table )

if you want to do a fix at runtime. ( prehaps just after you setTransObject )

Opening the painter and reseting the update table ( against a db with the proper capitilization ) should also fix up the dw.

I would not capatalize all the syntax, if you are not using bind variables it could cause problems.
