Re: 4 join methods?
I did have to RTFM - A cluster join is nothing more than a nested loops join involving two tables that are stored together in a cluster. Because each row from the dept table is stored in the same data blocks as the matching rows in the emp table, Oracle can access matching rows most efficiently Sam - Original Message - From: Vadim Gorbounov To: Multiple recipients of list ORACLE-L Sent: Friday, June 01, 2001 6:25 PM Subject: RE: 4 join methods?

RE: 4 join methods?
Hi Greg, I think Tim is right. I've read all the thread and among all other suggestions cluster join might have been the best answer. But if I remember correctly it is a kind of N-L Now going to read the article. Thanks for the link Regards, Ed I also sent an inquiry to Tim Gorman, who wrote the article on the CBO. He's no novice. He says the fourth join method is 1. nested loops 2. sort merge 3. hash join and 4. cartesian product ! I kid you not. By the way, if you're on 8i and haven't already set init parms OPTIMIZER_INDEX_CACHING=90 and OPTIMIZER_INDEX_COST_ADJ to something between 10 and 50, you might really like this article he wrote, The Search for Intelligent Life in the CBO.

Re: 4 join methods?
Most people think of cartesian product as a type of SQL coding that produces a result set where all rows in one table are joined to all rows in another. This could be accomplished by any of the three commonly known join methods. For example,select ename , dname from emp , dept/Execution Plan--SELECT STATEMENT Optimizer=CHOOSE NESTED LOOPS TABLE ACCESS (FULL) OF 'DEPT' TABLE ACCESS (FULL) OF 'EMP'Above a cartesian product SQL is resolved by a nested loops join method. I notice in explain plans a sort merge step appears as: ... MERGE JOIN...However, in 8.1.6, and possibly before, Oracle may resolve a query against a large child table and two small parent tables by first performing a cartesian product on the smaller tables, then joining the result set with the large table. This is invoked with the STAR hint and may happen without the hint if you happen to join one large table with two smaller lookup tables. In this case the step where the smaller tables are joined appears as:... MERGE JOIN (CARTESIAN)...This does not happen because the SQL is written as a cartesian product, and the results do not reflect a join of all rows to all rows. The cartesian product is merely an intermediate step used to optimize processing. My question is whether theMERGE JOIN (CARTESIAN)step is a separate join method. Certainly it is not the normal processing for what is typically understood to be SQL that creates a cartesian product, which could be resolved with any of the three ordinary join methodsseen in explain plans. I have searched the Oracle documentation and find no explanation for the difference between an explain plan step MERGE JOIN, which we know is a sort merge method, and a step MERGE JOIN (CARTESIAN), which as far as I can tell is never mentioned in the documentation, and which apparently represents the mysterious fourth method!Does anyone know where I can find any further information on MERGE JOIN (CARTESIAN)?

An index join is a hash join on 2 or more indexes which between them contain all the columns required to fulfill the query. It is new to 8i, and is considered to be an access pathl but strangely is not considered to be a join method; probably because it is a hybrid of the hash join using indices only.

i don't think it is considered a join, from what I remember it was called merging indexes. Walking on water and developing software from a specification are easy if both are frozen. Christopher R.

No, Oracle 8i will actually merge indexes and perform a pseudo join when possible without going to either table directly.

Re: 4 join methods?
I also sent an inquiry to Tim Gorman, who wrote the article on the CBO. He's no novice. He says the fourth join method is 1. nested loops 2. sort merge 3. hash join and 4. cartesian product ! I kid you not. By the way, if you're on 8i and haven't already set init parms OPTIMIZER_INDEX_CACHING=90 and OPTIMIZER_INDEX_COST_ADJ to something between 10 and 50, you might really like this article he wrote, The Search for Intelligent Life in the CBO.
