DataView RowFilter: using distinct

I have the following line of code (.NET 2.0):

myDataView.RowF ilter = "SELECT DISTINCT CYCLE_DATE";

where CYCLE_DATE is one of my column names. This throws the following
exception:

Syntax error: Missing operand after 'DISTINCT' operator.

Any suggestions on what this is really trying to tell me?

Thanks,
Randy

This is wrong. The RowFilter does not take a "Select" statement. It only
takes the part that would go after the "Where" in a "Select" statement, such
as
myDataView.RowF ilter = "field1>27 AND field2<45". Since the "distinct" does
not go after the "where", the dataview is not adequate for doing the kind of
filtering that you want.

IIRC, you can't use DISTINCT in a row filter. There's an article on MSDN
on how to get around this in code, I believe.

Not sure what group this question is better suited for so I sent it to both. I have a DataTable which contains 1545 rows. I have a method that returns a DataTable of distinct rows based on one column. This table ends up with 386 rows. I need to loop through the smaller table and filter a DataView based on each row from this table. This loops takes ~5 secs. Is there anyway to improve this?

I have a dataset (called adset) which has a column called "Large" which is either an integer 0 or 1. I am creating 2 dataviews, one which should display the 1's and one which should display the 0's using the following code: DataView largeview = new DataView(); largeview.RowFilter = "Large=1"; largeview.Table = adSet1.Tables; DataView smallview = new DataView();

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
