Solution 2

There is a simple way to do it for the data you show:

SQL

SELECT Name, MAX(Col1), MAX(Col2)
FROM MyTable
GROUP BY Name

But it may not work quite as you want if you have more than one non-null value.

This would work on the data set he showed.

However, I think he actually wants SUM. Please see my answer.

Solution 1

Try
select A.name,A.col1,(select col2 from table B where A.name = B.name and col2 !=null) from table A where col1 != null

I am sure you wanted to use IS NOT NULL instead of != null :)

Solution 3

Like this:

SQL

SELECT
    Name,
    SUM((ISNULL(Col1, 0))) AS Col1,
    SUM((ISNULL(Col2, 0))) AS Col2
FROM
    TEMP
GROUP BY Name
