Update certain data in SQL with JSP - sql

Question

i've been learning web programming (JSP and SQL) for the past few days, i need help with certain problem, so i need to show the list of all name of members from my database, add button beside it, and when i click it, i need to update the data in database, which name is exactly the same name besides the button .
I have successfully show the data and button, and i know syntax for updating in SQL, but i have no idea how to validate when i click the button, it updates the data with the same name exactly besides the button. Let's just pretend all name is unique. This is my sample code:
<div id="textArea">
<%
String query = "SELECT * FROM member";
ResultSet rs = st.executeQuery(query);
while(rs.next()){%>
<table>
<tr>
<td><%out.print(rs.getString("Fullname"));%></td>
<td> <input type="button" value="Change Role"/> </td>
</tr>
</table>
<%
}
%>
</div>
Any help is really appreciated. thanks!

You have to write Java code in a JSP Page for updating certain data from JSP.
You can write Java Code inside a scriptlet in a JSP page.
You have to write scriptlet inside <% ...%> tag, Please see sample below:
<%
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test");
Statement st=con.createStatement();
......
%>
Please follow the post below to execute update query directly from JSP:
