Hi!
pls suggest which of the two queries fetch result set faster.
option - 1
| Code: |
select tab1.a1,tab2.x2
from tab1,tab2
where tab1.a1 = 'aaa'
and tab1.a3 = tab2.x1 |
option - 2
| Code: |
select tab1.a1,tab2.x2
from tab1 inner join tab2
on tab1.a3 = tab2.x1
where tab1.a1 = 'aaa' |
Note:
1.index has been created on tab1(a1) and on tab2(x1)
2.row count of both the tables are 60,000+ |
