Well, first off you have left yourself wide open to SQL Injection attacks... Do not concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Use Parametrized queries instead.

Secondly, check that the class column is declared as NVARCHAR not VARCHAR.

If it is, look at the code you are using to retrieve the data - it may be that that has the problem.

You're welcome!
Please change data type of column [class] to NVARCHAR from VARCHAR. Hope your problem will be resolved.

And do you think you added something useful/new after about 7 years that is not already included in Solution 1? I suggest to delete this answer to prevent you from "down votes" ;)
