I mainly use MySQL these days, so get screwed over for a few minutes when I have to do something in MSSQL that is slightly different when it comes to it’s custom syntax.

If you want to show all entries in a specific column and where it is not Null then you can do the following:

SELECT [columnNameHere]
FROM [databaseNameHere].[dbo].[databaseTableNameHere]
WHERE [columnNameHere] IS NOT NULL
