Der Suchfilter in der Funktion unten scheint nicht zu funktionieren. Wenn ich keinen search Parameter zur Verfügung stelle, funktioniert es, sonst bekomme ich kein Recordset zurück. Ich gehe davon aus, dass ich das Single-Quoting und ILIKE durcheinander bringe, bin mir aber nicht sicher, wie ich das richtig umschreiben soll. Vorschläge?Dynamische RETURN EXECUTE Query mit ILIKE in Postgresql
