Hi Hugh, We made a breakthrough ;).
It seems like I left a small detail out of my previous example which was really important. declare somestr varchar; somestr := cast( __ro2sq( a_rdf_box ) as varchar ); -- notice that we are using __ro2sq() regexp_match( somestr ... ); -- no matter what pattern, this yields an error. However, if we do this: somestr := somestr || '' ; -- add an empty string Before calling the regexp function, it all runs OK. Thesis: Lazy coercion of some kind not being applied by the regexp evaluator?
