    <p>I'm trying to delete a row from my MS access database using checkboxes. I have the database outputted to my JSP page, each row has a checkbox. I'm having trouble getting the rowId and also linking each checkbox with a row. Any help would be much appreciated. Thanks. </p> <pre><code>&lt;%@ page import="java.io.*,java.util.*,java.sql.*"%&gt; &lt;%@ page import="javax.servlet.http.*,javax.servlet.*" %&gt; &lt;%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%&gt; &lt;%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;DELETE Operation&lt;/title&gt; &lt;script&gt; checkboxes = document.getElementsByTagName("input"); for (var i = 0; i &lt; checkboxes.length; i++) { var checkbox = checkboxes[i]; checkbox.onclick = function() { var currentRow = this.parentNode.parentNode; var secondColumn = currentRow.getElementsByTagName("td")[1]; alert("My text is: " + secondColumn.textContent ); }; } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;sql:setDataSource var = "bookdB" scope = "session" driver = "sun.jdbc.odbc.JdbcOdbcDriver" url = "jdbc:odbc:bookdB" /&gt; &lt;c:set var="empId" value="103"/&gt; &lt;sql:update dataSource="${bookdB}" var="count"&gt; DELETE FROM Employees WHERE Id = ? &lt;sql:param value="${empId}" /&gt; &lt;/sql:update&gt; &lt;sql:query dataSource="${bookdB}" var="result"&gt; SELECT * from Employees; &lt;/sql:query&gt; &lt;table border="1" width="100%"&gt; &lt;tr&gt; &lt;th&gt;&lt;/th&gt; &lt;th&gt;Emp ID&lt;/th&gt; &lt;th&gt;First Name&lt;/th&gt; &lt;th&gt;Last Name&lt;/th&gt; &lt;th&gt;Age&lt;/th&gt; &lt;/tr&gt; &lt;c:forEach var="row" items="${result.rows}"&gt; &lt;form method="post" action="reserve.jsp"&gt; &lt;tr&gt; &lt;td&gt;&lt;input type = "checkbox" value="reserve"&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${row.id}"/&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${row.first}"/&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${row.last}"/&gt;&lt;/td&gt; &lt;td&gt;&lt;c:out value="${row.age}"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/form&gt; &lt;/c:forEach&gt; &lt;input type = "submit" value="Delete"&gt; &lt;/table&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p><img src="https://i.stack.imgur.com/WcGAC.png" alt="MS access database screenshot"></p> <p><img src="https://i.stack.imgur.com/A62Re.png" alt="image 2"></p>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
