Re: TADODataset.Filter?

Oops! I forgot to quote the search string! The correct syntax would be:

// name starts from "bi"
ADOQuery1.Filter := 'name Like ' + QuotedStr('bi*');

// name contains "bi"
ADOQuery1.Filter := 'name Like ' + QuotedStr('*bi*');

Sorry for the error!

Bill.


I tried this tonight and got a most surprising result:

No error message and no filtering?

I single-stepped the application and could see that
ADODataset1 was "loaded" with a separate SQL SELECT
statement. Then whenever I changed the filter mask
(in an edit box) I could see that the following statements
were executed

1: ADODataset1.Filtered := false;
(typically) 2: ADODataset1.Filter := 'name LIKE ' + QuotedStr('bi*');
3: ADODataset1.Filtered := true;

but the DBGrid display did not change, it still displayed
the entire dataset?

Now I am lost? (It is 2:15 AM here and I am going to bed.)
