Set or change the database collation using SSMS Alternatively, if the database already exists, right-click the database that you want and select Properties. Select the Options page, and select a collation from the Collation drop-down list. After you are finished, select OK.

The default collation for SQL Server user-defined column is inherited from the database configured collation. If the database collation is changed, then the existing columns will retain the original collation but new columns will be created with current database collation. AND OBJECT_NAME(OBJECT_ID) = '?'

If you are using Unicode data types (nchar, nvarchar, ntext), there is no difference in the sorting behavior for the SQL and the Windows collations. Both will use Unicode sorting rules. In short, windows collations perform as slow as Unicode data types, and SQL collations perform much faster.

SQL collation specifies how to sort and compare character data based on language or region norms. Collations prevent language-specific sorting bugs. It can be set for instance, database, column, or expression. Windows collation is recommended for new development.

In a database, a collation is a set of rules that determine how data is sorted and compared, usually applied to how text data is sorted in different languages for the purpose of indexing text data and for making comparisons between text values. Different languages have different character sets and ordering.

Collations in SQL Server provide sorting rules, case, and accent sensitivity properties for your data. Collations that are used with character data types, such as char and varchar, dictate the code page and corresponding characters that can be represented for that data type.

The server collation is specified during SQL Server installation. The default server-level collation is based upon the locale of the operating system. For example, the default collation for systems using US English (en-US) is SQL_Latin1_General_CP1_CI_AS.

A collation specifies the bit patterns that represent each character in a dataset. Collations also determine the rules that sort and compare data. SQL Server supports storing objects that have different collations in a single database.

Changing the instance collation involves the following steps: Make sure you have all the information or scripts needed to re-create your user databases and all the objects in them. Export all your data using a tool such as the bcp Utility.Drop all the user databases.

You can use the COLLATE clause to apply a character expression to a certain collation. Character literals and variables are assigned the default collation of the current database. Column references are assigned the definition collation of the column.
