I have a table and it is having 2 columns

Col1 Col2
120 390
124 null
138 null
140 450

Now i want the o/p as

Col1 Col2
120 390
124 124
138 138
140 450

Can any one suggest how to achieve this?

-Thanks N Regards,
Chinna.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.

Or

SELECT Col1, COALESCE(Col2, Col1) AS Col1
FROM Table1

E 12°55'05.63"
N 56°04'39.26"

Ah - o/p = output.

(s.b. "AS Col2" :) )

Thanks! I missed that one...

SELECT Col1, COALESCE(Col2, Col1) AS Col2
FROM Table1

E 12°55'05.63"
N 56°04'39.26"
