There is a small amount of code inside of #ifdef ENABLE_OUTER_JOINS but it is not even close to what needs to be present for anything to run. Bruce and I were talking about an implementation, but it is definitely not coming for v6.5. - Thomas Oh, the syntax has lots of variants, but the basic one is: select * from t1 left|right|full outer join t2 on t1.x = t2.x; or select * from t1 left|right|full outer join t2 using (x); -- Thomas Lockhart lockhart@alumni.caltech.edu South Pasadena, California
