Hi Mark! Sorry for the delayed answer.
Thanks for the explanation, I get it too, although it works a little weird. I tested it in IBExpert, it works "well" under ISQL. The IBExpert preprocessor seems to have misunderstood something. Thanks!

The problem is related to the fact that the parentheses in EXECUTE PROCEDURE are optional, so execute procedure ex('Exception ') || 'message'; is equivalent to execute procedure ex(('Exception ') || 'message'); That is, the value passed as an argument is not `'Exception'`, but the expression `('Exception') || 'message'`. So, this part is not a bug as far as I'm concerned, just a weird corner case due to ambiguous syntax. The second part of your question, I cannot reproduce. In both cases the result is an exception with message 'exception message', not just 'message'. How are you executing this? The result in ISQL is: SQL> execute procedure ex('Exception') || 'message'; Statement failed, SQLSTATE = HY000 exception 1 -GL_EX -Exceptionmessage -At procedure 'EX' line: 9, col: 3 SQL> execute procedure ex('Exception ') || 'message'; Statement failed, SQLSTATE = HY000 exception 1 -GL_EX -Exception message -At procedure 'EX' line: 9, col: 3 SQL> execute procedure ex('Exception') || ' message'; Statement failed, SQLSTATE = HY000 exception 1 -GL_EX -Exception message -At procedure 'EX' line: 9, col: 3 SQL> -- Mark Rotteveel Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel Firebird-Devel mailing list, web interface at https://lists.sourceforge.net/lists/listinfo/firebird-devel
