Hello i have 7 text boxes and on each click off the button i want to save the data to single row in data base table so how can i do something like this

What I have tried:

private void button1_Click(object sender, EventArgs e)
        {
CON.Open();
string SQLQUERY = "INSERT INTO table1 (name1,last1,first1,second1,top1,bottom1,last1)VALUES(@text1, @text2, @text3, @text4, @text5, @text6, @text7)";

    next
string SQLQUERY = "INSERT INTO table1 (name2,last2,first2,second2,top2,bottom2,last2)VALUES(@text1, @text2, @text3, @text4, @text5, @text6, @text7)";
