SQL - How to get the Unique Key's Column Name from Table

Question

I know how to get the columns from a table using the following SQL statement:

SELECT COLUMN_NAME 
FROM INFORMATION_SCHEMA.COLUMNS 
WHERE (TABLE_NAME = \'MYTA         


        

Answer 1

Something like this might work (untested):

SELECT *
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS TC
WHERE TC.TABLE_NAME = 'MYTABLENAME'
AND TC.CONSTRAINT_TYPE = 'UNIQUE'
