When I add this to my where clause: DueDate <= getDate() AND DueDate IS

  • 0

When I add this to my where clause:

DueDate <= getDate() AND DueDate IS NOT null

I get a nice little failure that says: Could not create child: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.Data.EvaluateException: The expression contains undefined function call getDate().

Any idea what I’m doing wrong?

Update Code in use:

private string getFilter(int mode) {     String filter = '';     if ((ALL_WORK_ORDERS & mode) == 0) {         if ((mode & OUTSTANDING_WORK_ORDERS) == OUTSTANDING_WORK_ORDERS) {             filter += 'DueDate <= getDate() AND DueDate IS NOT null OR';         }         if ((mode & COMPLETED_WORK_ORDERS) == COMPLETED_WORK_ORDERS) {             filter += ' FinishedDate IS NOT  null';         }     }      filter = filter.Trim();     if (filter.EndsWith('OR')) {         filter = filter.Remove(filter.Length - 2);     }      return filter; }

And it is getting used here:

tblWorkOrderBindingSource.Filter = getFilter(mode);

In the table, DueDate is type datetime.

Side note: I can run 

SELECT [ID]       ,[WorkDesc]       ,[DueDate]   FROM [RentalEase].[dbo].[tblWorkOrder] WHERE [DueDate] <= getDate() AND [DueDate] IS NOT null

in the MS SQL Server Management Studio Express without a problem.

Final Solution

    private string getFilter(int mode) {         String filter = '';         if ((ALL_WORK_ORDERS & mode) == 0) {             if ((mode & OUTSTANDING_WORK_ORDERS) == OUTSTANDING_WORK_ORDERS) {                 filter += 'DueDate <= #' + DateTime.Now.ToShortDateString() + '# AND DueDate IS NOT null  AND FinishedDate IS null OR';             }             if ((mode & COMPLETED_WORK_ORDERS) == COMPLETED_WORK_ORDERS) {                 filter += ' FinishedDate IS NOT null';             }         }          filter = filter.Trim();         if (filter.EndsWith('OR')) {             filter = filter.Remove(filter.Length - 2);         }          return filter;     }

  1. The exception is pretty clear on what is wrong here. You are specifying a method, getdate, which can’t be used in a filter expression. See the documentation on the Expression property on the DataColumn class for what is valid and what is not:

    http://msdn.microsoft.com/en-us/library/system.data.datacolumn.expression.aspx

    That being said, instead of getdate, you need to concatenate the date into the filter (call the static Now property on the DateTime structure to get the current date). The link above will show you how to format dates properly (you can’t just do it as indicated in Kelly’s answer, although that answer is most of the way there).
