Answer 1

In your first insert statement there is a "," after Remark, I believe this could be causing the invalid syntax error.

String my_querry = "INSERT INTO crtPro(Name,AR,Wereda,Kebele,House_No,P_O_Box,Tel,Fax,Email,Item,Dep,Status,Remark**,**

//this will add a data into multiple table.

    {

    }

    {
