Hi
Below is the query :
Select C1,C2 from T1,T2 where T1.C1 = T2.C1
and C3 < ( Select NEW_COL from T3 where T1.C1 = T3.C1)
and C9 >= ( Select NEW_COL from T3 where T1.C1 = T3.C1)
and C11 > ( Select NEW_COL from T3 where T1.C1 = T3.C1) ;
Here when the above query runs , Select for T3 executes thrice.
Is there any way to tune this as the same column value is being checkd against three colums. |

Try
| Code: |
Select C1,C2 from T1,T2,T3
where T1.C1 = T2.C1
and T1.C1 = T3.C1
and C3 < T3.NEW_COL
and C9 >= T3.NEW_COL
and C11 > T3.NEW_COL ;

Ashimer ,
This would give results from T3 table also. I do not want the data from T3. |
