Hello Everyone,

I have a database view. I need to give some conditions . Not able to fiure out how should I proceed.

I know the section where to put the selection conditions.

My condition is :

Table1-field2 eq 'X' and ( Table1- field1  eq 'X'  or( Table2-field1 eq 'X' and Table2-field2 eq 'X' )) and

i am not able to implement the highlighted part. How can I give this nesting in the conditions.

Kindly give your inputs.
