Could any one tell me, how the index works in cache db, Consider for example, I have a table called "Employee" and the fields as "EMPID, EMPNAME, EMPAGE" and I am having index for EMPID as IDX_EMPID and trying to get the record using the following query as

SELECT * FROM EMPLOYEE WHERE EMPID="005"

and the table data be like

EMPID EMPNAME EMPAGE

001 ABC 20

002 AAA 21

003 ABB 23

004 BBB 20

005 BDF 24

006 EEE 22

0 2
0 106
