Mar 5, 2011 · Is there any way in SQL Server of determining what a character in a code page would represent without actually creating a test database of that collation? Example. If I create a test database with collation SQL_Ukrainian_CP1251_CS_AS and then do CHAR(255) it returns я.

When you create a Microsoft SQL Server DB instance, you can set the server collation that you want to use. If you don't choose a different collation, the server-level collation defaults to SQL_Latin1_General_CP1_CI_AS. The server collation is applied by default to all databases and database objects.

There is a set of collations that support only the Unicode encodings and cannot be set on a database level. These collations have Code Page = 0 (see Figure 1). Here is an interesting example of how these collations work with the non-Unicode data. Sorting rules
