    <p>I'm making an C# windows Form Application in visual studio 2010.</p> <p>That application is connecting to an mysql database, and I want to insert data in it.</p> <p>Now do I have this part of code:</p> <pre><code>MySqlConnection connection; string cs = @"server=server ip;userid=username;password=userpass;database=databse"; connection = new MySqlConnection(cs); connection.Open(); MySqlCommand command = new MySqlCommand(); string SQL = "INSERT INTO `twMCUserDB` (`mc_userName`, `mc_userPass`, `tw_userName`, `tw_userPass`) VALUES ('@mcUserName', '@mcUserPass', '@twUserName', '@twUserPass')"; command.CommandText = SQL; command.Parameters.Add("@mcUserName", mcUserNameNew); command.Parameters.Add("@mcUserPass", mcUserPassNew); command.Parameters.Add("@twUserName", twUserNameNew); command.Parameters.Add("@twUserPass", twUserPassNew); command.Connection = connection; command.ExecuteNonQuery(); connection.Close(); </code></pre> <p>The connection is fine. That works.</p> <p>I readed <a href="https://stackoverflow.com/questions/7174792/does-using-parameterized-sqlcommand-make-my-program-immune-to-sql-injection">here</a> that the way that I have now, is an save way to do query's. Is that still right?</p> <p>And now to the real question. With that code above, I get the following warning in visual studio:</p> <pre><code>'MySql.Data.MySqlClient.MySqlParameterCollection.Add(string, object)' is obsolete: '"Add(String parameterName, Object value) has been deprecated. Use AddWithValue(String parameterName, Object value)"' </code></pre> <p>That warning is for every parameters.add</p> <p>And it isn't even working, because the values that are inserted are @mcUserName, @mcUserPass and so on, instead of the values that the variables mcUserNameNew and so on are holding...</p> <p>So my question is, am I doing something wrong, and what is the new way to sql injection save do an query?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
