has to be able to step backwards in the second data stack each time it moves forwards a row in the first data stack. One side effect of this is that the merge join is not completely symmetrical despite comments in the manual, the second data is always fully acquired, sorted, and instantiated; it cannot be acquired piece-wise (for example, by walking an index) like the first data set. Given the increasing complexity of the work that has to be done, especially in the last three joins, we might expect the cost of the merge join to vary with the type. Script merge_samples.sql in the online code suite demonstrates queries that match the pictures, and produces the execution plan results: alter session set hash_join_enabled = false; create table t1 as with generator as ( select --+ materialize rownum id from all_objects where rownum <= 3000 ) select rownum id, rownum n1, trunc((rownum - 1)/2) n2, lpad(rownum,10,'0') small_vc, rpad('x',100,'x') padding from generator v1, generator v2 where rownum <= 10000 ; alter table t1 add constraint t1_pk primary key(id); ----select count(distinct t1_vc ||t2_vc) from ( select /*+ no_merge ordered use_merge(t2) */ t1.small_vc t1_vc, t2.small_vc t2_vc Create table t2 in the same fashion Collect statistics using dbms_stats here The following statement has different predicates, corresponding to the five pictures in the diagram

from t1, t2 where ----) ; t1.n1 <= 1000 and t2.id = t1.n1 <= 1000 and t2.n2 t1.n1 <= 1000 and t2.id t1.n1 <= 1000 and t2.n2 t1.n1 <= 1000 and t2.n2 t1.id = t1.id between t1.id - 1 and t1.id + 1 = t1.n2 between t1.n2 - 1 and t1.n2 + 1

If we want to specify that the derived class function is a new function, not intended to override the base function, we append new to the function signature as in Listing 8-5. Listing 8-5. Using new to Override Overriding // new_method.cpp using namespace System; // the game library's classes ref class GameObject { public: void Initialize(bool fromFile) { if (fromFile) { Read(); } else { // other code } } virtual void Read() { Console::WriteLine("GameObject::Read"); } };

There are a few cool tips and tricks you can use to make filing, locating, and using your memos even easier. These include adding separate items for each store you need to shop from; placing numbers in front of your memo names, and adding a space in front of list items to indicate they are checked off.

When testing 9i and 8i, I set hash_join_enabled to false to stop the optimizer from choosing a hash join on the simple equality queries. Unfortunately, 10g ignored this setting so I had to include the hints ordered and use_merge(t2) to force the optimizer to use a merge join. Things keep changing, and it s a real nuisance how bits of code suddenly become obsolete and stop working. Watch out, for example, for the parameter _optimizer_sortmerge_join_enabled, introduced in 9i; one day it may silently default to false and all your merge joins will change to nested loop or hash joins!

The surprising thing about the five different execution plans is that the final cost is the same for all of them, even though there are slight variations in the plans and distinct changes in the cardinality of the joins. For example: Execution Plan (9.2.0.6 autotrace, no system statistics, 1 to 1 with equality) -----------------------------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=105 Card=1 Bytes=14) 1 0 SORT (GROUP BY) 2 1 VIEW (Cost=105 Card=1000 Bytes=14000) 3 2 MERGE JOIN (Cost=105 Card=1000 Bytes=34000) 4 3 SORT (JOIN) (Cost=38 Card=1000 Bytes=19000) 5 4 TABLE ACCESS (FULL) OF 'T1' (Cost=29 Card=1000 Bytes=19000) 6 3 SORT (JOIN) (Cost=68 Card=10000 Bytes=150000) 7 6 TABLE ACCESS (FULL) OF 'T2' (Cost=29 Card=10000 Bytes=150000) Execution Plan (9.2.0.6 autotrace, no system statistics, many to many with range) --------------------------------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=105 Card=1 Bytes=14) 1 0 SORT (GROUP BY) 2 1 VIEW (Cost=105 Card=25002 Bytes=350028) 3 2 MERGE JOIN (Cost=105 Card=25002 Bytes=850068) 4 3 SORT (JOIN) (Cost=38 Card=1000 Bytes=19000) 5 4 TABLE ACCESS (FULL) OF 'T1' (Cost=29 Card=1000 Bytes=19000) 6 3 FILTER

It s not uncommon to go to a hardware or grocery store for a particular item, purchase several additional items while you are there, yet also forget to pick up the one item you actually went to that store to buy. Adding separate items for each store you need to shop from to a memo can help you avoid forgetting that one particular item you are supposed to get, saving you time and gas money!

SORT (JOIN) TABLE ACCESS (FULL) OF 'T2' (Cost=29 Card=10000 Bytes=150000)

ref class Item : GameObject { // ... }; // the user's class ref class Scroll : Item { public: virtual void Read() new { // Read the scroll in the game environment. Console::WriteLine("Scroll::Read"); } }; int main() { Scroll^ scroll = gcnew Scroll(); Item^ item = scroll; item->Initialize(true); scroll->Read(); } The output of Listing 8-5 is as follows: GameObject::Read Scroll::Read You might wonder about the new keyword being used here in a different context. Isn t that a problem It s not a problem because the compiler is sensitive to the context in which the new keyword is used.
