Subject: /*+ NO_STAR_JOIN */ and Indexes
HI All,
Can we run a query which contains both /*+ NO_STAR_JOIN */ as well as /*+
INDEX(INDEXED_TABLE INDEX/ in the same query ??
I am running a query like :
Select /*+ NO_STAR_JOIN Index("Address" "Address_Index") Index("Customers"
"Customer_Index") Index("Orders" "Order_Index") Index("Order_Details"
"Order_Detail_Index") */ * from "Address" as a
inner join "Customers" as c on a."A_C_Id" = c."C_Id"
inner join "Orders" as o on a."A_C_Id" = o."O_C_Id"
inner join "Order_Details" as od on od."O_Id" = o."O_Id"
inner join "Payterms" as p on p."Payt_Id" = o."O_Pay_Terms"
inner join "Shipterms" as s on s."Shipt_Id" = o."O_Ship_Terms"
where c."C_Name_Id" = 'Zameer100002';
and I see no performance benefits over the above query where I don’t use the
Index criteria in the same query. Is there any other syntax that I should be
using.
P.S :” Select /*+ NO_STAR_JOIN */ /*+ Index("Address" "Address_Index")
Index("Customers" "Customer_Index") Index("Orders" "Order_Index")
Index("Order_Details" "Order_Detail_Index") */ * from "Address" as a………….” I
tried this combination but I got an error. ☹
Thanks,
