 <p>The first solution works fine, I get all areas except the ones of TBA, HBA and AWN. (My datasource is a POSTGIS-DB)</p> <p>I tried the other two as well:</p> <ul> <li>EXPRESSION /^[TBA|HBA|AWN]/: I get the areas of TBA,HBA and AWN (with NOT it doesn't work) </li> <li>EXPRESSION ("[zustaendigkeit]" NOT IN "TBA,HBA,AWN"): I don't get anything</li> </ul> <p>Thanks.</p>
