使用方法;

例如想查询的内容具有以下结构
struct account{
        char        user[36];
        byte        password[16];
        uint32_t        status;
        uint32_t        id;
};

//声明查询bind 结构account,参数4个
DECL_BIND(account,4)
        BIND_BIN(user,32)
        BIND_BIN(password,16)
        BIND_INT(status)
        BIND_INT(id)
END_BIND(account)

int main(){

        try{
               
                DBMysql        sql/Index.html'>mysql;
                sql/Index.html'>mysql_parm        parm;
                parm.host="localhost";
                parm.user="root";
                parm.password="test";
                parm.unixsock="/var/lib/sql/Index.html'>mysql/sql/Index.html'>mysql.sock";
                parm.database="testdb";
                sql/Index.html'>mysql.open(parm);//打开数据库
               
                DBSTMT        smt("select user,password,status,id from account",sql/Index.html'>mysql); //生成一个查询语法
                DBSTMT        smt1("insert into account(user,password,status) value(?,?,?)",sql/Index.html'>mysql); //另外一个
        //
               
                bind_account        acc;
