Hi Guys,

I am at a loss if i run the following statement in MySQLworkbench it works fine. However when I try using the ODBC connection in c# i get the following error;

ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.1.56-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT @@IDENTITY' at line 1

the SQL i am using is very simple;

connection = new OdbcConnection(connectionString);
            connection.Open();

            String oQRY = String.Format("INSERT INTO `message` (fromID,subject,message,date,important) VALUES ({0},'{1}','{2}','{3}',{4}); SELECT @@IDENTITY AS `identity`;", userID, SubjectTextBox.Text, MessageMemo.Text, timestamp, ImportantCheckBox.Value);
            //Response.Write(oQry + "<BR>")
            OdbcCommand com = new OdbcCommand(oQRY, connection);
            com.ExecuteNonQuery();
            com.CommandText = "SELECT Last_Insert_ID()";
            int messageID = (int) com.ExecuteScalar();

the value of oQRY is

"INSERT INTO `message` (fromID,subject,message,date,important) VALUES (0,'test','test','2011-03-16 00:00:00',True); SELECT @@IDENTITY AS `identity`;"

any ideas whats going on here please?

Thanks in advance,

Matt.

Replace with this query

            String oQRY = String.Format("INSERT INTO `message` (fromID,subject,message,date,important) VALUES (SELECT @@IDENTITY AS `identity`,'{0}','{1}','{2}',{3});", userID, SubjectTextBox.Text, MessageMemo.Text, timestamp, ImportantCheckBox.Value);

Hope this helps
