I have two tables:
1. Incomes
Income Amount
Salary 10000
Sales 55000
and 2. Expenses

Expense Amount
House Rent 3000
Tution 4000
Fooding 4000
Travelling 2000

I want to join these to tables to form:
Salary 10000 Expense Amount
Sales 55000 House Rent 5000
(null) (null) Tution 4000
(null) (null) Fooding 4000
(null) (null) Travelling 2000

How can it be done. Thanks

What does Sales 55000 have in common with House Rent 5000?

Why do you want to do this?

What's your applicationenvironment? ASP?
