PipeLine Function Taking time to return Table record

Question

Hi,
I want to use a function in join clause. so i go for pipelined function(using for loop to get record & 1 more loop to fetch in table type variable). i achieved what i required. but problem is it takes much time to fetch data. is there any other approach which returns table records without pipelined function.
please suggest me a better approach as soon as possible.

Answer 1

Hi,
Thanks all for the quick response.
I am using oracle 10g
this is the table details & the entire function.
Create object & table type to use in the function
CREATE OR REPLACE TYPE SYSADM.STR_TYPE AS OBJECT(COLUMNVALUE VARCHAR2(8),FromNo Int,ToNo Int)
CREATE OR REPLACE TYPE SYSADM.STR_ARRAY AS TABLE OF STR_TYPE
table involved
View : VesselType
column : Code varchar2(5)
Table : T065_SHIP
column : SKIPS_KODE varchar2(4)
CODE_SHIPTYPE varchar2(5)
Table : SelsKap
column : SELSKAPSKODE varchar2(4)
Table : t041_shiptypeusers
column : Code_ShipType varchar2(5)
USERID varchar2(8)
View : PositionBook
column : VesselCode varchar2(8)
VoyageNo integer
Company varchar2(4)
Table : T62_BRUKER_SELSKAP
column : SELSKAPSKODE varchar2(4)
BRUKER varchar2(8)
Pipelined function
CREATE OR REPLACE FUNCTION SYSADM.TF_ShiporShipTypeByUser
