i am using a datawidow to deal with a table which contains a identity field. i dont care to show this field on the screen but i want this field to auto-increment its value by one when i insert a new record to the database. How can i deal with this field in design time? And what about the update properties of the datawindow?
if i dont include it in the sql statement ( i believe this is the right thing to do) will this field increase its value by one every time i add a new record? In case that i would like to display this field in the screen but not update it thru keyboard what should i do?
i would like something else too. (not concerning identity fields). suppose we execute the command dw_1.update() . can we get at run time the exact command that powerbuilder sends to the database? Suppose this datawindow has a field named xx with tab order 10. how can i change it to 0 in run time?
i am using pb 11.5 and sql server 2000

Hi,
Also, forgot to mention,
In update properties, there is a dropdown to select the identity column.Please select your identity column from there.
In the above post i have asked not to select the identity column in the updateable columns section. Try selecting it and see if its giving any noteable issues.
Cheers,
Rosh

Hi,
You can include the identity column in the SQL of your datawindow.
In the update properties, dont select the identity column in the updateable columns section.
So now u can display the column aswell.
DW_1.GetSQLPreview ( )
This will give u the sql sent to the database.
Also, have a look in PB Help at SQLPreview Event of DW.
At runtime to change the taborder,
dw_1.Object.emp_name.TabSe
or,
dw_1.Modify("emp_name.TabS
Cheers,
