Question

using this query,

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.Columns where TABLE_NAME <table>

how would i modify it to select only column names that are primary keys? or keys of any type?

Using the same type of select is prefered.

Answer 1

SELECT *
FROM INFORMATION_SCHEMA.Table_Constraints tc
    JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE kcu
        ON tc.TABLE_NAME = kcu.TABLE_NAME
            AND tc.TABLE_SCHEMA = kcu.TABLE_SCHEMA
            AND tc.TABLE_CATALOG = kcu.TABLE_CATALOG
            AND tc.CONSTRAINT_NAME = kcu.CONSTRAINT_NAME
WHERE tc.TABLE_NAME = 'table_name'
