I have a table about 1,100,000 records.
Create Table Card
(No char(10),
Client char(15),
...
Status(1),
)
Status in ('1','2','3','4','5')
the status of each card change from '1' to '5'
the status of new card is '1',the finished status is '5'
after system runs for a long time,
'1' 3%
'2' 5%
'3' 5%
'4' 10%
'5' 77%
we always do the query with status '4' and '1'
How should I create indexes on the table(normal indexes or bitmap indexes)?
