Compiled Linq & String.Contains
- by sharru
i'm using linq-to-sql and i'm use complied linq for better performance.
I have a users table with a INT field called "LookingFor" that can have the following values.1,2,3,12,123,13,23.
I wrote a query to return the users based on the "lookingFor" column
i want to return all users that contains the "lookingFor" value (not only those equal to it).
In example if user.LookingFor = 12 , and query paramter is 1 this user should be selected.
private static Func<NeDataContext, int, IQueryable<int>>
MainSearchQuery = CompiledQuery.Compile((NeDataContext db, int lookingFor) =>
(from u in db.Users
where (lookingFor == -1 ? true : u.LookingFor.ToString().Contains(lookingFor)
select u.username);
This WORKS on non complied linq but throws error when using complied.
How do i fix it to work using complied linq?
I get this error:
Only arguments that can be evaluated on the client are supported for the String.Contains method.
