Oracle's traditional non-ANSI standard left outer join query, your query is equivalent to the following two queries if using ANSI stardard: 1. select tbl1.xx, tbl2.xx from tbl1 LEFT OUTER JOIN tbl2 on tbl1.col1=tbl2.col2; or 2. select tbl1.xx, tbl2.xx from tbl2 RIGHT OUTER JOIN tbl1 on tbl2.col2=tbl1.col1;

I see. Thanks a lot. The syntax is a little strange. tbl1 get all records when tbl2 has a (+) there.

哈哈,如果你习惯了 +=, =+ syntax, 看 ANSI out join syntax 还觉得别扭哪。
(+) is the best expression. ANSI out join is for some who is not a DB developer.

To do "full outer join" using old oracle outer join syntax, you will need a UNION to union left and right outer join. Oracle old +=, =+ syntax in most cases are more concise than ANSI syntax, but ANSI full outer join syntax seems more concise than += UNION =+ old syntax.
