Index SKIP SCAN???

Index Skip Scan nada mais é que o "split" logico de um indice composto, ou seja, se sua clausula WHERE não tiver todos os campos do indice composto, ele é dividido em menores sub-indices Exemplo: -------- SQL> create table teste(a number,b number); Table created. SQL> begin 2 for i in 1..1000 3 loop 4 insert into teste values(i, 56); 5 end loop; 6 end; 7 / PL/SQL procedure successfully completed. SQL> create index idx_teste on teste(a,b); Index created. SQL> analyze table teste compute statistics; Table analyzed. SQL> explain plan for select /*+ index_ss(teste idx_teste) */ * from teste where b=56; Explained. SQL> start ?\rdbms\admin\utlxpls.sql -------------------------------------------------------------------------------- | Operation | Name | Rows | Bytes| Cost | Pstart| Pstop | -------------------------------------------------------------------------------- | SELECT STATEMENT | | 1

With the next option, i tried to use the IdcCommand, but still had many problems, such as errors below: sample hda file: [oracle @ hostname bin] $ cat idctst.txt @Properties LocalData IdcService = EDIT_RENDITIONS dID = 37020 renditionKeys = addRendition0 addRendition0.name = test543 addRendition0.action = edit addRendition0.file = test.txt addRendition0.file: path = / u01 / oracle / domains / content_domain / ucm / cs / vault / ~ temp / test.txt @end << EOD >> Executing: [oracle @ hostname bin] $ ./IdcCommand -f idctst.txt -u sysadmin -l log.log -c server Error: Java HotSpot (TM) 64-Bit Server VM warning: Using the ParNew young collector with the Serial old collector is deprecated and w
