A) command.CommandText = "exec uspLoginAudit;"; using (SqlConnection connection = new SqlConnection( "Integrated Security=SSPI; Initial Catalog=pubs")) {
connection.Open();
command.ExecuteNonQuery();
}
B) command.CommandText = "USE [pubs]; exec uspLoginAudit;"; using (SqlConnection connection = new SqlConnection( "Integrated Security=SSPI; Initial Catalog=AdventureWorks")) {
connection.Open();
