SQL Server 2008 :: Easy Way To Compare Contents Of Objects Between 2 Different Databases?

Is there an easy way to compare the contents of objects between 2 different databases? For example, say I had 2 databases, My_DB_1 and My_DB_2, each with a SEC_User table. Say I wanted to do an object-to-object comparison between databases to see if there were any differences. Here's some sample SQL:

use My_DB_1
select * from sys.dm_sql_referencing_entities('dbo.sec_user', 'object')

use My_DB_2
select * from sys.dm_sql_referencing_entities('dbo.sec_user', 'object')

Say that the result sets above both returned a SEC_GetUser sproc object ref. Is there a way to write SQL that will compare the SEC_GetUser sprocs (and other objects in the above rowsets) from both databases? For example, if My_DB_1.SEC_GetUser returns an extra column in the result set than My_DB_2.SEC_GetUser then I'd like my comparison SQL to return a single column "IsDifferent" with SEC_GetUser as a row....
