sql server - Query to check whether a column is nullable

Question

Query to check whether a column is nullable (null values are allowed in the column or not). It should preferably return yes/no or 1/0 or true/false.

Answer 1

You could retrieve that from sys.columns:

select  is_nullable 
from    sys.columns 
where   object_id = object_id('Schema.TheTable') 
        and name = 'TheColumn'
