Question

lets say I have tableA which has a col1 and tableB which has col2 with the following content:

Table A
---------
A
B
C
D


Table B
---------
1
2
3
4

I want a select statement that returns to me:

A, 1
B, 2
C, 3
D, 4

I have tried making this call:

Select tableA.col1, tableB.col2 from tableA, tableB 

but it returns the following:

A, 1
B, 1
C, 1
D, 1
A, 2
..
..
 etc

how can i get it to just pull back this:

A, 1
B, 2
C, 3
D, 4

Answer 1

Try this:

select b.val1, b.val1, c.val2 from tableA a
inner join (select ROW_NUMBER() OVER () AS RowNumber, col1 as val1 from tableA) on a.col1 = b.val1
inner join (select ROW_NUMBER() OVER () AS RowNumber, col2 as val2 from tableB) c on c.RowNumber = b.RowNumber
