Compare stored procedures across multiple databases (SQL Server)

SQL Gurus --

Our architecture consists of multiple customer databases to a common codebase. When we deploy database changes, the scripts must be run agianst each database.

Because of deployment issues, there have come times when our stored procedures became out of sync with one another. I would like to create a script to return these mimatched procedures to ensure that we have sync'd copies of our databases after deployment.

Is it possible to compare two or more databases, by having a script look at all the procedures between two databases, and return the mismatches?

Something to the effect of:

DATABASE_1 | DATABASE_2  | MISMATCHED_PROCEDURE | DATABASE_1_MODIFY_DATE | DATABASE_2_MODIFY_DATE
Customer_1 | Customer_2  | sp_get_names         | 1/1/2010               | 1/2/2010
Customer_1 | Customer_2  | sp_add_person        | 1/5/2010               | 1/6/2010

As a bonus, would it be possible to have the script automatically sync the databases by applying the newest script to the out-of-date script?

Much Thanks!

There are many tools to do this. One of the best is Red-Gate SQL Compare. Another very good alternative is to use Visual Studio Database Professional to manage your database schema. Among other things, it will do very nice schema compares.

If you don't have SQL Compare or Visual Studio team system for DB architects (Data Dude)...play around with this...SQL 2005 and up

select t1.name,t1.modify_date,t2.modify_date
 from Database1.sys.procedures t1
join Database2.sys.procedures t2 on t1.name  = t2.name
and  object_definition(t1.object_id) <>  object_definition(t2.object_id)

Use the following:

   SELECT DISTINCT
      o1.name AS Object_Name1,
      o1.type_desc as type_desc1,
      o2.name AS Object_Name2,
      o2.type_desc as type_desc2
   FROM DB1.sys.sql_modules m1
   INNER JOIN DB1.sys.objects o1
   ON m1.object_id = o1.object_id
   FULL OUTER JOIN DB2.sys.sql_modules m2
   INNER JOIN DB2.sys.objects o2
   ON m2.object_id = o2.object_id
   ON o1.name = o2.name
   WHERE isnull(m2.definition,'') <> isnull(m1.definition,'')

Simplistic answer but a drop and create script on all procedures would be very easy and effective.
