Indexes

[former_member445996]

Hi All,

Is there a way to specify which index to use in the select statement?

Thanks

i think it will depend on the fields which u will be using in the select statement and fields for which indexes are created

Use the word "HINT" with the index name in your SELECT statement.

Aurang,

Also - look in OSS for notes about the "HINT" syntax in Open SQL. There are examples there for you to review.

Database will automatically use Index based on the where clause. So always try to write where clause based on the index fields and in the same sequence.

Hi Khan,

You can use the fields of the index in the WHERE clause of the select statement, in the order of occurence.

Hi Anurag,

Have a look at the following code.

SELECT COUNT(*)

FROM crmd_orderadm_h

WHERE process_type IN git_t_type

AND object_type = gc_subobject

AND object_id IN git_t_no

%_HINTS ORACLE 'INDEX("CRMD_ORDERADM_H" "CRMD_ORDERADM_H~OID")'.

Here I am using the index OID defined for the table CRMD_ORDERADM_H.

Hello Anurang,

The selection of index cannot be manually controlled as it is the databsae which selects the best index for execution. Howerver after saying this SAP has come up with an exception from 4.5 where u can use the keyword %HINT to force the database into using a perticular index. Please refer to OSS notes 129385.
