LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method

Question

I have executed a linq query by using Entityframework like below

GroupMaster getGroup = null;
getGroup = DataContext.Groups.FirstOrDefault(item => keyword.Ind         


        

Answer 1

You really only have four options here.

1. Change the collation of the database globally. This can be done in several ways, a simple google search should reveal them.
2. Change the collation of individual tables or columns.
3. Use a stored procedure and specify the COLATE statement on your query
4. perform a query and return a large set of results, then filter in memory using Linq to Objects.

number 4 is not a good option unless your result set is pretty small. #3 is good if you can't change the database (but you can't use Linq with it).

numbers 1 and 2 are choices you need to make about your data model as a whole, or if you only want to do it on specific fields.
