Christopher Miller read article of SQL SERVER Database Coding Standards and Guidelines Complete List Download and came up with wonderful SQL Server Script to rename all their database constraint with more organized constraint names, which helps to easily identify the constraint database exist on.
Christopher Miller – “When we submit our schema updates internally, we usually catch any deviation from our naming conventions. It’s not a perfect process and every now and then, something slips through the cracks. We then correct the schema update to use the appropriate naming convention. if we have been using the schema changes internally, we may have some databases that don’t match the published schema for the object names. When that happens, we run a simple T-SQL script that cleans house. The following T-SQL will scan the database for default constraints that do not match our naming conventions and rename the ones that it finds.”
