When you update data in the DataWindow painter, PowerBuilder builds a SQL UPDATE statement in the background. The DateFormat parameter determines how PowerBuilder specifies a date datatype when it builds the SQL UPDATE statement.

DateFormat='date_format '
Parameter |
Description |
|---|---|
date_format |
The date format you want PowerBuilder to use when it builds a SQL UPDATE statement to update a data source in the DataWindow painter. For more on display formats, see the Users Guide. |
If no value is specified for the DateFormat parameter, PowerBuilder does not use a date datatype.
When you call stored procedures, the database server might not accept the date format built by PowerBuilder. If this occurs, you can try to use another format. For example, for Microsoft SQL Server, try this format:
DateFormat='\''yyyy-mm-dd\'''
Assume you are updating a table named Employee by
setting the Startdate column to 2006-04-23. This date is represented
by the date format yyyy-mm-dd.
To specify that PowerBuilder should use this format for the date datatype when it builds the SQL UPDATE statement:
Database profile Type the following in the Date Format box on the Syntax page in the Database Profile Setup dialog box:
yyyy-mm-dd
Application Type the following in code:
SQLCA.DBParm="DateFormat='yyyy-mm-dd'"
What happens PowerBuilder builds the following SQL UPDATE statement to update the table:
UPDATE EMPLOYEE
SET STARTDATE='2006-04-23'
