Re: URGENT Join question

Debo:

That's because there indeed DOES exist a row which satisfies your where clause. The second row of a combined with the (only) row of b satisfies it because the join condition is true (col2 = col2) AND the <> condition is also true ('HELLO WORLD NOW' does not equal 'HELLO WORLD'). What are you trying to do?
