Hi All,

I have a scenario.The query is a select from a view which has got some tables with nearly 100000 records in it.The query is something like this.

select a.name,a.number,a.description from details_v a where a.name like '%&1%' order by a.name.

The tables in the view are all analyzed.But still when the query is returning only 388 recotds it takes more than 2 min.And also the explain plan uses index row_id on the tables.

call     count    cpu elapsed   disk  query current  rows
------- ------  ----- ------- ------ ------ -------  ----
Parse        1   0.01    0.00      0      0       0     0
Execute      1   0.01    0.00      0      0       0     0
Fetch       20  58.19  153.22 395102 919346       0   388
------- ------  ----- ------- ------ ------ -------  ----
total       22  58.21  153.23 395102 919346       0   388

Any pointers would be of immense help.

Thanks,

The "a.name like '%&1%'" clause will probably result in at least 1 Full Table Scan. (normally) No index can be used if the first character(s) are not known.

It all depends on the construction of the view. Tkprof without the query and the plan won't tell much.

The query is basically a Oracle APPS LOV query.
The like parameter is constructed at runtime by the Form.

select oec.customer_id, OEC.name, OEC.customer_number
from
OE_SOLD_TO_ORGS_V OEC WHERE UPPER(NAME) LIKE :1 AND (NAME LIKE :2 OR NAME
LIKE :3 OR NAME LIKE :4 OR NAME LIKE :5) order by oec.name.
