How can I ignore accents (like ´, `, ~) in queries made to a SQL Server database using LINQ to SQL?

UPDATE:

Still haven’t figured out how to do it in LINQ (or even if it’s possible) but I managed to change the database to solve this issue. Just had to change the collation on the fields I wanted to search on. The collation I had was:

SQL_Latin1_General_CP1_CI_AS

The CI stans for ‘Case Insensitive’ and AS for ‘Accent Sensitive’. Just had to change the AS to AI to make it ‘Accent Insensitive’. The SQL statement is this:

ALTER TABLE table_name ALTER COLUMN column_name column_type COLLATE collation_type

  1. In SQL queries (Sql Server 2000+, as I recall), you do this by doing something like select MyString, MyId from MyTable where MyString collate Latin1_General_CI_AI =’aaaa’.

    I’m not sure if this is possible in Linq, but someone more cozy with Linq can probably translate.

    If you are ok with sorting and select/where queries ALWAYS ignoring accents, you can alter the table to specify the same collation on the field(s) with which you are concerned.
