Hallo
I have a table with coloumn name "Periode" that contain year such 2011, 2012 and years with prefix B-2011 or W-2012.
Now I want to set a filter on coloumn "Periode" for table that should show only records which start with a letter eq. "B" oder "W". Type of Periode is VARCHAR.
Coudl you please advice where to set this filter in a best way?
Thanks
