<p>Use the <tsx:dbmodify> syntax to establish a connection to a database and then add records to a database table.</p>
|
||
|
|
|
||
|
|
<p>The <tsx:dbmodify> tag:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Refers to a <tsx:dbconnect> in the same JSP file and uses the information provided by that database connection to determine the database URL and driver. The user ID and password are also obtained from the <tsx:dbconnect> if those values are provided in the <tsx:dbconnect>.</li>
|
||
|
|
|
||
|
|
<li>Establishes a new connection.</li>
|
||
|
|
|
||
|
|
<li>Updates a table in the database.</li>
|
||
|
|
|
||
|
|
<li>Closes the connection (releases the connection resource).</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>The <tsx:dbmodify> syntax is:</p>
|
||
|
|
|
||
|
|
<pre><tsx:dbmodify connection="<em>connection_id</em>" >
|
||
|
|
|
||
|
|
<!-- Any valid database update commands can be ->
|
||
|
|
<!-- placed within the tsx:dbmodify tag. Any other ->
|
||
|
|
<!-- syntax, including HTML comments, are not valid. ->
|
||
|
|
|
||
|
|
</tsx:dbmodify></pre>
|
||
|
|
|
||
|
|
<p>This list describes the attributes and their values:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li><p><strong>connection</strong>
|
||
|
|
<br>The identifier of a <tsx:dbconnect> in this JSP file. That <tsx:dbconnect> provides the database URL, driver name, and (optionally) the user ID and password for the connection.</p></li>
|
||
|
|
|
||
|
|
<li><p><em>Database commands</em>
|
||
|
|
<br>For more information about database commands, see this resource:</p>

<p>In the following example, a new employee record is added to a database. The values of the fields are based on user input from this JSP and referenced in the database commands using the <tsx:getProperty> tag.</p>

<pre><% String empno = request.getParameter("EMPNO"); %>

<% String lastname = request.getParameter("LASTNAME"); %>
