Question

i am trying to do a substring search from an access 2010 database in winforms.

command.Parameters.AddWithValue("@searchTerm", searchTerm);
command.CommandText = "SELECT [OA_Name] FROM [Operating_Authority_Table] WHERE [OA_Name] = [@%searchTerm%]";

I tried to do a full string search and able to do just that, but I can’t get any successful searches when i change the term to be a substring.

am i implementing the wildcard character wrongly?

Try something like this:

command.Parameters.AddWithValue("@searchTerm", searchTerm); 
command.CommandText = "SELECT [OA_Name] FROM [Operating_Authority_Table] WHERE [OA_Name] = '%' + @searchTerm + '%'";
