For the following code,

SqlParameter prmStudentName = new SqlParameter("@StudentName", studentName);

SqlParameter prmReturnResult = new SqlParameter("@ReturnResult", System.Data.SqlDbType.Int);
prmReturnResult.Direction = System.Data.ParameterDirection.Output;

result = context.Database
.ExecuteSqlRaw("EXEC @ReturnResult = usp_ AddStudentDetails @ StudentName”, prmReturnResult, prmStudentName);
returnResult = Convert.ToInt32(prmReturnResult.Value);

what is the value of the variable result when NO rows are affected in the database? Assume that the procedure usp_AddStudentDetails contains one update and one insert statement and the procedure returns 1, only if they are executed successfully.
