Hi Everyone, This week, I was able to send the com_stmt_execute command from the *Driver * in the way it is accepted by the MariaDB server So, Now I am able to insert a row in the database using com_stmt_execute command. But from the console when I try to see the values I see *NULL* I used *Wireshark* to capture the packets,but I can see the value(Varchar /Int/..etc) is passed in the packet which wireshark captures. I am investigating the code but could not find anything till now. In Wireshark it shows* [Expert Info (warn/undecoded) :FIXME: Excute Dissector Incomplete]* Now I think I am not sending the values in a correct format.Will look and try to resolve it.
