Hi!
I've got a simple problem with a create table statement: CREATE TABLE HB_ATTRIBUTE (

	STRINGVALUE VARCHAR2(4000 CHAR),
	DATEVALUE DATE,
	CONSTRAINT TCC_HB_ATTRIBUTE_1 CHECK ((STRINGVALUE is null)<>(DATEVALUE is 
null)) DEFERRABLE INITIALLY DEFERRED);

This gives me an "ORA-00907: missing right paranthesis" at the "<>". I have no idea what I'm doing wrong.
I'm using 10.2.0.1.0 on linux 32 bit.
Can anybody help me out?

Lots of Greetings!
Volker
