In this tutorial, we will see how you can check your current collation settings and then change them if necessary. So as you can see, your SQL collation settings will d epend on the region or language that the database is being used for. Mainly there are various rules or collations that exist in SQL Server but we need to know the following 2 main collations. Otherwise, you could find that an application generates characters that the database is not able to handle and throws out errors as a result. What is collation Collation is nothing but a set of rules that are predefined in SQL Server that determine how the data in SQL Server are stored, retrieved and compared. This is an important setting that has a huge impact on how the SQL Server.
In these cases, having the right collation settings is really important. Collation is a configuration that determines how character data sorting is done. To understand how important this is, think about characters used in other languages, such as the ‘ñ’ in Spanish, or characters used in Arabic or Japanese, for example. More specifically, SQL collation specifies the bit patterns that represent each character in a regional character set and the rules for comparing and organising data. With the COLLATE clause, you can override whatever the default collation is for a comparison. COLLATE can be used at the database level or the column level. SQL Collation is basically a set of rules about how characters, such as accents, uppercase, lowercase and other supported characters, are encoded and ordered in the database. Based on the collation names I assume that you are using Microsoft SQL Server. If you haven’t configured SQL collation properly for your database, it can trigger a raft of problems for both the database and the applications that connect to it.īut why do these problems happen? Why is this feature so important? What does it do? Unfortunately, if you don’t understand how this feature, there’s a chance that it could cause you a real headache.

In fact, pretty much anyone who has ever set up an SQL server or an application like Microsoft System Center will have had to configure these settings, but most of the time, people simply follow the default installation settings without really knowing what it is or how to change it. Most sysadmins don’t know what collation is until they start having problems with it.
In this tutorial, you will learn how to change your SQL collation settings.
