You can change the server-level collation either during setup or by changing the OS locale before installation.

You must also take care to guarantee the correct translation of characters from any of the languages when the characters are read by clients that are running a code page for another language.The code pages that a client uses are determined by the operating system (OS) settings. https://docs.microsoft.com/en-us/sql/relational-databases/collations For example, when you construct a query by using To best use collation support in SQL Server, you should understand the terms that are defined in this topic and how they relate to the characteristics of your data.A collation specifies the bit patterns that represent each character in a dataset. Although it might seem natural, the default With SQL Server 2019 (15.x), both UTF-8 and UTF-16 encodings are available to represent the full range:The following table lists the encoding storage bytes for each character range and encoding type:As you've just seen, choosing the appropriate Unicode encoding and data type might give you significant storage savings or increase your current storage footprint, depending on the character set in use. Cette invention concerne également un nouveau système incorporé de compression d'images et d'expansion en temps réel pour la Refer to the Transact-SQL script or the SQL Notebook in the To change the column collation and data type in an existing table, use one of the methods described in To change the database collation, allowing new objects to inherit the database collation by default, or to change the server collation, allowing new databases to inherit the system collation by default, see the For more information, see the following related content: Collations in SQL Server provide sorting rules, case, and accent sensitivity properties for your data. The rules also specify the code page that's used to store non-Unicode character data. Mais heureusement dans les versions les plus récentes, il est possible de corriger ce réglage sans avoir à tout réinstaller.Faisons le test. Two different character sets cannot have the same After they're stored in the server, they're treated as Unicode characters in any subsequent operations.You can use any Chinese collation, preferably the latest 100 version. This topic describes how set and change the database collation in SQL Server 2019 (15.x) by using SQL Server Management Studio or Transact-SQL. ; Vérifier si les éléments d'un volume à relier sont bien placés dans l'ordre. UTF-8 is allowed in the UTF-8 is available only to Windows collations that support supplementary characters, as introduced in SQL Server 2012 (11.x). Unicode collations must be selected individually at the database, column, or expression level because they aren't supported at the server level.When you move data from a server to a client, your server collation might not be recognized by older client drivers. If no collation is specified, the server collation is used.Altering database collation is not explicitly forbidden in Azure SQL Database. The The Unicode Consortium allocates to each character a unique code point, which is a value in the range 000000â10FFFF. For example, There are two types of binary collations in SQL Server:SQL Server collations (SQL_*) provide sort order compatibility with earlier versions of SQL Server. For example, when you use a Latin collation that's UTF-8 enabled, such as Before you choose whether to use UTF-8 or UTF-16 encoding for a database or column, consider the distribution of string data that will be stored:Therefore, it's required to know in advance what's the projected byte size for the column definition before converting existing data to UTF-8, and adjust the new data type size accordingly. Choose a collation that maps to a code page on the client.To use the UTF-16 collations that are available in SQL Server (SQL Server 2012 (11.x) and later) to improve searching and sorting of some Unicode characters (Windows collations only), you can select either one of the supplementary characters (_SC) collations or one of the version 140 collations.To use the UTF-8 collations that are available in SQL Server 2019 (15.x), and to improve searching and sorting of some Unicode characters (Windows collations only), you must select UTF-8 encoding-enabled collations(_UTF8).To evaluate issues that are related to using Unicode or non-Unicode data types, test your scenario to measure performance differences in your environment.
