Assuming the Existence of an Operator template <class T> ref class A { // assumes T supports the + operator T add(T t1, T t2) { return t1 + t2; } }; If you want a generic class that does this, you probably need to define an interface constraint and add that interface to any types that are to be used as a type argument, as in Listing 11-32..

E-mail Message Filters (Only for BlackBerry Enterprise Server users)

This looks like a better bet than having to reread the probe partitions multiple times because the build partitions are too big to be held in memory (There is clearly a break point at about two where there is no point in trying to subpartition the hash table) Of course, on the downside, you have to worry about the extra complexity in the code, and the possibility that this recursive hash join would have to be applied to the subpartitions, and their subpartitions, and so on And each time you descend into recursion, you have to take out more memory for mapping and other overheads and since the multipass is only invoked when you are short of memory anyway, a recursive hash join may not really be a sensible thing to do.

While receiving your e-mail messages on your BlackBerry is a wonderful thing, there might be some e-mail messages that, for whatever reason, you don t want sent to your BlackBerry. Fortunately, you can use an e-mail filter to see just which messages you want sent to your BlackBerry and which ones stay on the server.

If you see multipass hash joins occurring and this is only likely to occur in a few special-case big jobs you need to consider strategies for increasing the available memory, changing the join mechanism, or redesigning the SQL..

Although I haven t built a test case that matches the description exactly, script hash_multi.sql in the online code suite gets quite close. It repeats the table definitions of script hash_one.sql, but then forces a hash join to take place with a hash_area_size of 128KB when the size of the build table is about 2MB. This is what happens to the execution plan: Execution Plan (9.2.0.6 Autotrace) ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=13531 Card=2000 Bytes=4114000) 1 0 HASH JOIN (Cost=13531 Card=2000 Bytes=4114000) 2 1 TABLE ACCESS (FULL) OF 'BUILD_TAB' (Cost=255 Card=2000 Bytes=2060000) 3 1 TABLE ACCESS (FULL) OF 'PROBE_TAB' (Cost=255 Card=10000 Bytes=10270000)

Notice how the cost of the tablescans has (of course) not changed, but the cost of the hash join has jumped from the onepass cost of 1,127 to a multipass cost of 13,531 The optimizer can always work out (in principle) how many partitions would be needed to achieve a onepass hash join But if the hash_area_size is too small to allow that many partitions to be created remember that each partition needs at least one block of memory at all times then the optimizer will recognize that a multipass join is required, and be able to work out how many passes will be required per probe partition If you call the number of passes N, then the excess cost of the multipass join will be the cost of writing out the possible match rows once, and rereading them N times.
