Converts bitmaps into key values and ROWIDS
This operation is implemented in the following versions
This example was developed using Oracle 220.127.116.11 on Windows 2000
This example requires the following table and index definitions
CREATE TABLE t1 (c1 NUMBER,c2 NUMBER); CREATE BITMAP INDEX i1 ON t1 (c1);
The table does not need to be analysed.
SELECT /*+ INDEX (t1 i1) */ ROWID FROM t1;
generates the following execution plan
0 SELECT STATEMENT Optimizer=CHOOSE 1 0 BITMAP CONVERSION (TO ROWIDS) 2 1 BITMAP INDEX (FULL SCAN) OF 'I1'
