Compiled Linq & String.Contains

Question

I\'m using Linq-to-SQL and I use compiled Linq for better performance.

I have users table with a INT field called \"LookingFor\" that can have the follo

Answer 1

I'm facing the same problem. I have managed for now just one workaround for this problem. Instead of using

u.LookingFor.ToString().Contains(lookingFor)

I've used

u.LookingFor.ToString().IndexOf(lookingFor) >= 0

Answer 2

You're performing operations on the lookingFor argument that cannot be translated to SQL. I'm actually surprised that this works when not compiling the query.

If it's possible, I suggest that you change your database to make this query easier. Create a table to store the LookingFor property for users. Or you can change the datatype of lookingFor to a string, which has less of an impact on the database design.
