Question

I am wondering how i can display data from column B if Column A is null. The reason is if we get a product from one of our manufactures it is put in a different column. However, when i go to build the report the two columns essentially the same thing and it is throwing the graph way off. Any help would be appreciated.

Something like this maybe?

Case When column A isnull then column B?

Answer 1

Use ISNULL() or COALESCE(), or CASE

SELECT    ISNULL(ColumnA, ColumnB) AS [YourColumn]
FROM      FOO

OR

SELECT    COALESCE(ColumnA, ColumnB) AS [YourColumn]
FROM      FOO

OR

SELECT    CASE WHEN ColumnA IS NULL THEN
              ColumnB
          ELSE
              ColumnA
          END AS [YourColumn]
FROM      FOO
