Snippet to quickly view computed column information. You can also view this by doing a “create table” script. This however, was a little cleaner to read and view for me.

select
database_name = db_name()
,object_schema_name = object_schema_name( object_id )
,object_name = object_name( object_id )
,full_object_name = object_schema_name( object_id ) + '.'
+ object_name( object_id )
,column_name = name
,cc.is_persisted
,cc.Definition
from
sys.computed_columns cc
order by
full_object_name asc
