![]() This is not recommended since it can influence existing query execution and query result sets.Ī list of collations supported by the installed version of SQL Server can be generated using sys.fn_helpcollations() With the assistance of the SQL Server Installation setup, collation can be changed, however, the effect of that on the current database and its tables can be unpredictable. Users can change the collation settings at the database level but not at the SQL Server level. New databases will be configured with the default collation of the SQL Server. SQL Server installation configuration sets the default collation for the created instance (Latin1_General_CI_AI). This distinction is important for data sorting in the query result set. For example, information in the column can be case sensitive, and lowercase letters will not be treated the same as uppercase letters. It matters which collation is associated with a column when ordering clause is applied to that column. When retrieving data using a T-SQL query, collation plays a fundamental role in the execution. ![]() Data always follows collation constraint rules, which are configured when creating an object. Collate SQL follows rules applied on a table when Select, Insert, Update orĭelete operations are performed against contained data. SQL Server collation refers to a set of character and character encoding rules, and influences how information is stored according to the order in the data page, how data is matched by comparing two columns, and how information is arranged in the T-SQL query statement.
