Hi,

I need to run some Entity Framework 6 executions under a different collation.

( I have not chance to modify my DB collation )

For example if the user is searching for a text containing the word "maría" (note the accent) EF should return

Maria
maria
maría
....

Using EF should you should do something like this:

var persons = context.Set<Person>().Where( p => p.firstName.Contains("maría") );

In transact sql there is an option

 selec * from Persons where firstName like '%maría%' 
collate Latin1_General_CI_AI;

I need to do something similar to force EF to run under other collation.

Thanks all !!!

What I have tried:

I've haven't tryed anithing yet :-)

Entity Framework doesn't have any collation. It's entirely dependent on the database doing that kind of work.

You can either execute a SQL statement you write, including the COLLATE clause, using EF and EF will happily hydrate the data into objects, or you do a database migration and alter the collation for the columns you want.

C#

string query = "SELECT ....";
var result = contextInstance.Database.SqlQuery<targetEntityType>(query);
