HI
i have to search for particular longitude/latitude value stored in sdo_ordinates_array (varray of numbers)
till now i am applying linear search but for the worst case (i.e if length of varray is too large) the execution time increases a lot.
also i cannot apply binary search here since elements in varray are not ordered .
my question is Is there any other seaching technique or search function available for type varray.
thanx in advance

Muhammad,

One thought - You could use a materialized view and extract the coordinates, making sure that the MV is indexed. Then do your queries on the MV.
