Hi All,

          I've 3 tables table x,y,z
pk of x is (col_1,col_2),pk of y is (col_1,col_2,col_4,col_5),pk of z is
(col_1,col_2)

where clause is :

where x.col_1 = y.col_1

and x.col_2 = y.col_2
and x.col_1 = z.col_1
and x.col_2 = z.col_2
and y.col_1 = z.col_1
and y.col_2 = z.col_2

and x.col_3 in ('val1','val2','val3')
and.....
..

Explain plan shows that there is a FTS of table z . what can be the reason for this and how to prevent this.

Thanks
Manoj
