SQL Compare 12

Permissions required to use SQL Compare

Comparing

The permissions you need to compare databases are:

SQL Server versionRecommended permissionsMinimum permissions  Permissions if you want to compare
encrypted objects
SQL Server 2008 and later

db_owner role

SELECT for the system view sys.sql_expression_dependencies
(without this permission, comparing databases can be very slow)

VIEW DEFINITION permission

sysadmin role

VIEW SERVER STATE permission

SQL Server 2005db_owner roleVIEW DEFINITION permissionsysadmin role

Deploying

For deployments, we recommend using the db_owner role. However, it's possible to deploy with just the permissions to make the changes listed in the Summary tab (on the Review page of the deployment wizard).

Exactly which permissions you need depends on the objects in your databases, and what you're deploying.

You can't deploy objects that are encrypted, if they're encrypted in the source.

Permissions issues

If you don't have the right permissions:

  • Some objects may be missing from the comparison results.
    For example, User Defined Types don't appear in the comparison results if you don't have permission to view the schema they belong to.
  • Deployments and deployment scripts may fail or have unexpected results.
    If a deployment fails, SQL Compare attempts to roll back the changes, using transactions. However, in some circumstances, rolling back isn't possible.
