After you finish installation for SQL server may be you want to change the Server collation or database Collation so leat’s see what will we do if we want to make this :
1- if you want to know what’s your database collation know
SELECT name, collation_name
FROM sys.databases WHERE name = ‘test’ — put your database name here
2- If you want to get a list of all available collations on the server using
SELECT * FROM ::fn_helpcollations()
3- Alter Database Collation
ALTER DATABASE test — put your database name here
COLLATE Arabic_CI_AS — replace with whatever collation you need
4- IF you want to know what’s your server collation
SELECT SERVERPROPERTY (‘Collation’)
