When you update data in the DataWindow painter, DataWindow Designer builds a SQL UPDATE statement in the background. The DateFormat parameter determines how DataWindow Designer specifies a date datatype when it builds the SQL UPDATE statement.
ADO.NET
OLE DB
DateFormat = 'date_format '
Parameter |
Description |
|---|---|
date_format |
The date format you want DataWindow Designer 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 User’s Guide. |
If no value is specified for the DateFormat parameter, DataWindow Designer does not use a date datatype.
When you call stored procedures, the database server might not accept the date format built by DataWindow Designer. 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 DataWindow Designer 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 tab in the Database Profile Setup dialog box:
yyyy-mm-dd
Application Type the following in code:
SQLCA.DbParameter = "DateFormat='yyyy-mm-dd'"
What happens DataWindow Designer builds the following SQL UPDATE statement to update the table:
UPDATE EMPLOYEE
SET STARTDATE = '2006-04-23'
