Collate Number Resolution For Free

You can specify collations for each character string column using the COLLATE clause of the CREATE TABLE or ALTER TABLE statement. You can also specify a collation when you create a table using SQL Server Management Studio. If you do not specify a collation, the column is assigned the default collation of the database.

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.

The Latin1_General_CI_AS collation is a Windows collation and the rules around sorting unicode and non-unicode data are the same. A Windows collation as per this example can still use an index if comparing unicode and non-unicode data albeit with a slight performance hit.

You can resolve the issue by forcing the collation used in a query to be a particular collation, e.g. SQL_Latin1_General_CP1_CI_AS or DATABASE_DEFAULT. In the above query a. MyID and b. YourID would be columns with a text-based data type.

Latin1_General_CI_AS does character expansions, where SQL_Latin1_General_CP1_CI_AS does not. You would need to discuss this further with your DBA since this will really depend on what the DB Server collation is set as, and what your needs are based on SQL vs Windows collation.

You need to cast the join columns to the same collation. Ideally you should sort out the collation in the database as casting negates the use of indexes.

Ing the SQL Server Books Online, the characters included in range searches depend on the sorting rules of the collation. Collation Latin1_General_CS_AS uses dictionary order so both upper and lower case characters of the specified range are included.

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.

SQL Server instance level collation If a user's database collation is configured differently than one of the SQL Server instance collation, then a comparison between tables in that database and in tempdb, when it comes to textual data comparison, will return an error.

To view the collation setting of a database In Object Explorer, connect to an instance of the Database Engine and on the toolbar, click New Query. In the query window, enter the following statement that uses the sys. databases system catalog view. SELECT name, collationname FROM sys.
