Descending indexes were introduced in Oracle8i to extend the functionality of a B*Tree index. They allow for a column to be stored sorted in descending order (from big to small) in the index instead of ascending order (from small to big). Prior releases of Oracle, pre-Oracle8i, always supported the DESC (descending) keyword syntactically, but basically ignored it it had no effect on how the data was stored or used in the index. In Oracle8i and above, however, the DESC keyword changes the way the index is created and used. Oracle has had the ability to read an index backward for quite a while, so you may be wondering why this feature is relevant. For example, if we use the table T from earlier and query it as follows: ops$tkyte@ORA10G> set autotrace traceonly explain ops$tkyte@ORA10G> select owner, object_type 2 from t 3 where owner between 'T' and 'Z' 4 and object_type is not null 5 order by owner DESC, object_type DESC; Execution Plan ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=82 Card=11395 Bytes=170925)

This implies that you have not taken the time to understand how the data will be used and how many rows you will ultimately require You ll be adding indexes to this system forever as the volume of data grows over time (ie, you ll perform reactive tuning) You ll have indexes that are redundant and never used; this wastes not only space but also computing resources A few hours at the start spent properly considering when and how to index your data will save you many hours of tuning further down the road (note that I said doing so will, not might, save you many hours) The basic aim of this chapter is to give an overview of the indexes available for use in Oracle and discuss when and where you might use them.

An aspect declaring an exception for a join point wraps the join point execution in a try/catch block. The catch block catches the original exception, and the throw block throws a SoftException that wraps the original exception. This means that in listing 4.21, if we were to specify execution instead of call in the pointcut, the compiler would still give us a compiler error for the unhandled exception. To illustrate this, let s look at the code in listings 4.20 and 4.21 again. First let s see that compiling TestSoftening together with SofteningTestAspect results in a woven TestSoftening class that looks like the following:

Oracle will just read the index backward. There is no final sort step in this plan; the data is sorted. Where this descending index feature comes into play, however, is when you have a mixture of columns, and some are sorted ASC (ascending) and some DESC (descending), for example: ops$tkyte@ORA10G> select owner, object_type 2 from t 3 where owner between 'T' and 'Z' 4 and object_type is not null 5 order by owner DESC, object_type ASC; Execution Plan ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=85 Card=11395 Bytes=170925) 1 0 SORT (ORDER BY) (Cost=85 Card=11395 Bytes=170925) 2 1 INDEX (RANGE SCAN) OF 'T_IDX' (INDEX) (Cost=82 Card=11395 ... Oracle isn t able to use the index we have in place on (OWNER, OBJECT_TYPE, OBJECT_NAME) anymore to sort the data. It could have read it backward to get the data sorted by OWNER DESC, but it needs to read it forward to get OBJECT_TYPE sorted ASC. Instead, it collected together all of the rows and then sorted. Enter the DESC index: ops$tkyte@ORA10G> create index desc_t_idx on t(owner desc,object_type asc); Index created. ops$tkyte@ORA10G> exec dbms_stats.gather_index_stats( user, 'DESC_T_IDX' ); PL/SQL procedure successfully completed. ops$tkyte@ORA10G> select owner, object_type 2 from t 3 where owner between 'T' and 'Z' 4 and object_type is not null 5 order by owner DESC, object_type ASC; Execution Plan ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=2 Card=11395 Bytes=170925) 1 0 INDEX (RANGE SCAN) OF 'DESC_T_IDX' (INDEX) (Cost=2 Card=11395 ... Now, once more, we are able to read the data sorted, and there is no extra sort step at the end of the plan. It should be noted that unless your compatible init.ora parameter is set to 8.1.0 or higher, the DESC option on the CREATE INDEX will be silently ignored no warning or error will be produced, as this was the default behavior in prior releases.
