Question

I want to change Collation of the whole database created by ef code first, I try to do it by running a script after creation but it does not works,

_dbContext.Database.Delete();
_dbContext.Database.CreateIfNotExists();
_dbContext.Database.ExecuteSqlCommand("ALTER DATABASE afi COLLATE French_CI_AI");

Is it possible to set the collation before creating the database?

That is the exception I get :

Resetting the connection results in a different state than the initial
login. The login fails. Login failed for user ‘afi’. A severe error
occurred on the current command. The results, if any, should be
discarded.

[SqlException (0x80131904): Resetting the connection results in a
different state than the initial login. The login fails.

Login failed for user ‘afi’. A severe error occurred on the current
command. The results, if any, should be discarded.]

Answer 1

A workaround may be to execute a sql command to create the database, rather than use _dbContext.Database.CreateIfNotExists();

_dbContext.Database.ExecuteSqlCommand(“

CREATE DATABASE [databasename] ON PRIMARY ( NAME = N’databasename’,
FILENAME = N’c:\PathToData\databasename.mdf’ , SIZE = 2048KB ,
FILEGROWTH = 1024KB ) LOG ON ( NAME = N’databasename_log’, FILENAME
= N’c:\PathToLog\databasename_log.ldf’ , SIZE = 1024KB , FILEGROWTH = 10%) COLLATE French_CI_AI

“);

I’ve put in a little spacing to make it easier to read, obviously change databasename to the name you want, and also PathToData and PathToLog.

If you change the collation of the server to French_CI_AI, all new databases will be created using this collation but it’s not always the best choice and will cause headaches if you are past the developement stage as it affects the temp_db database as well (temporary tables and other temporary objects).
