Question

Can someone point me in the direction on how to write a query to pull all the column names from a table that are not primary keys or alternate keys. I would specifically like to exclude alternate keys from my queries.

Answer 1

DECLARE @tableName nvarchar(max) = 'table_name'

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE TABLE_NAME = @tableName

EXCEPT

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS [tc]
JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE [ku] ON tc.CONSTRAINT_NAME = ku.CONSTRAINT_NAME
    AND ku.table_name = @tableName
