The database collation is used for all metadata within database, and therefore collation is that default for all string columns, temporary objects, variable names, and other strings used in database. To find server-level collation for an SQL Server, use below query : SELECT CONVERT(varchar, SERVERPROPERTY('collation')) Instead of changing default collation of an instance of SQL Server, you’ll be able to specify required collation once you create new database or database column. The default server collation is set during SQL Server setup, and it becomes default collation of system databases and user databases.Īfter you’ve assigned collation to server, you’ll be able to change it only by exporting all database objects and data, rebuilding master database, and importing all database objects and data. SQL Server supports following levels of collations : To find list of collations that are available on instance of SQL Server, use the below : SELECT * FROM sys.fn_helpcollations() To check server collation for an instance of SQL Server, use the below : SELECT SERVERPROPERTY('collation') When Binary (_BIN) or Binary-code point (_BIN2) is chosen, other collation options aren’t available.
