SQL_Latin1_General_CP1_CI_AS v. Latin1_General_CP1_CI_AS

Can any help me with understanding the difference between SQL_Latin1_General_CP1_CI_AS and Latin1_General_CP1_CI_AS?

I've read some stuff, but I'm still unclear. If the same collation is used within a single database, does it matter which one of these I use? Is it only performance? If all our data character is english, does it matter which is used?

Is the default collation different for SQL server versions?

I understand about sticking with one collation within the database.

I have two databases, one is a development database and one is a production database, and they are on SQL servers that are different versions and that have a different default collation. During development, I add a text columns to a table, and the column defaults to SQL_Latin1_General_CP1_CI_AS. I did the same on the production database. Then before we do a production release of code I use a software tool to sync the schema between the development and production databases, to make sure everything is the same. The production database has a default collation of Latin1_General_CP1_CI_AS. So, the tool always pick up on this difference for a column that was manually created in both databases. Question - Is this an issue? Sounds like it is, since the schema tool will now change the collation on the column from Latin1_General_CP1_CI_AS to SQL_Latin1_General_CP1_CI_AS.

Follow up - Is there a way to check the collation on all text columns within a database ? I want to see if they are all the same.
