Hi there. We are trying to save a datawindow syntax into a table column of type longvarchar.
It was working fine previously with 3 groupby clauses but as soon as we add 4th group by
it won't load. all the groupby's are defined in the datawindow painter The trailer for this new group has 10 computed fields. The datawindow has about 35 columns including computed fields in the trailer bands
for the groupby's. If I remove all computed fields in the new trailer band the datawindow saves fine.


/******** Validate the Syntax of Datawindow *************/	 	
ls_data_source = event ue_datawindow_syntax() 	
IF ls_data_source = "FALSE"  OR  (dw_1.create(ls_data_source,ls_err_buffer ) = -1 ) THEN 
messagebox("Dynamic Reports","Failed to Upload the Dynamic Reports   " +  is_datawindow_name  + ".~r~n Please Contact with IS Department",true)
		IF dw_report_header.deleterow(0) = 1 THEN 
			dw_report_header.update() 
			triggerevent ("ue_reset")
			RETURN -1
		END IF
	END IF

Open in new window

could be the length of datawindow syntax being returned is more than the size of longvarchar column. Check the sqlca.sqlerrtext after the updating that column.

If that is the case then either increase the size of column (if possible) or change the datatype to longbinary or blob or clob(whatever is available and larger in the database you are using).

Sandeep if you look at the attached code its not failing trying to save but  rather when the syntax
is being checked before saving. I have checked SQLCA.SQLCODE. It is 0. The command
dw_1.create(ls_data_source,ls_err_buffer )  is failing.
The ls_err_buffer has a value =  "incorrect syntax" .
iS there a way to check the datawindow syntax and why it is failing

Thanks

what is the code in 'ue_datawindow_syntax' and what it returns to 'ls_data_source'?
Paste the code and value of ls_data_source here.

As you are creating or changing anything dynamically, and there is some PB datawindow syntax error which cause the problem.
