FDTable filter problem

Recommended Posts

I have done filtering in other databases with no problem.

This time I am using FDTable, My tries

ProjectsFDTable.Filtered:=false;

ProjectsFDTable.Filter:='Category =' +QuotedStr('Tools');

OR

ProjectsFDTable.Filter:='Category = Tools';

ProjectsFDTable.Filtered:=True;

Category is the column Tools is the data

The errors are mainly - Tools cannot be found as the Column <<<< how come?

With the QUERY component I have no problem but for my reasons

I want to do it with FDTable.

Any idea

PS. I tried with ProjectsFDTable.SQL nothing worked.

Which Delphi version. I've never used TFDTable but tested successfully in D11 the code:

 

ProjectsFDTable.Filter:='Category =' +QuotedStr('Tools');
ProjectsFDTable.Filtered:=true;


It's working.

I read that, unfortunately I have no access to your working environment I can only confirm what's working at my side.

 

I do not have D10.2.3 to test, tried with XE5 it's also working without a problem there.

If you've the source of FireDAC you can debug FireDAC.Stan.Expr there are 4 cases when this exception is raised.
