2. Single record binding
A single record binding is used to display only a single row of data. For example, consider the following code:
ID: <span datasrc= "#dsoData" datafld= "au_id" ></SPAN><BR>
Name: <span datasrc= "#dsoData" datafld= "au_fname" ></SPAN><BR>
Last Name: <span datasrc= "#dsoData" datafld= "au_lname" ></SPAN><BR>
Phone: <span datasrc= "#dsoData" datafld= "Phone" ></SPAN><BR>
Address £ <span datasrc= "#dsoData" datafld= "Address" ></SPAN><BR>
City: <span datasrc=, "#dsoData" datafld= "City" ></SPAN><BR>
State: <span datasrc= "#dsoData" datafld= "state" ></SPAN><BR>
Zip: <span datasrc= "#dsoData" datafld= "Zip" ></SPAN><BR>
Contact: <span datasrc= "#dsoData" datafld= "contract" ></SPAN><BR>
With a single record binding, each bound HTML element determines the data source (DATASRC) and the bound field (DATAFLD).
The results of the above data binding are shown in Figure 10-5:

As a result, this already satisfies the requirements, but because the space is ignored in the HTML document, the data is not arranged neatly. Data binding makes it easy to get data, but it doesn't look very nice. A good way to do this is to use a table to align the data.
<table id= "Tbldata" >
<TR><TD>ID:</TD>
<td><span datasrc= "#dsoData" datafld= "au_id" ></SPAN></TD></TR>
<tr><td>first name:</td>
<td><span datasrc= "#dsoData" datafld= "au_fname" ></SPAN></TD></TR>
<tr><td>last name:</td>
<td><span datasrc= "#dsoData" datafld= "au_lname" ></SPAN></TD></TR>
<TR><TD>Phone:</TD>
<td><span datasrc= "#dsoData" datafld= "Phone" ></SPAN></TD></TR>
<TR><TD>Address:</TD>
<td><span datasrc= "#dsoData" datafld= "Address" ></SPAN></TD></TR>
<TR><TD>City:</TD>
<td><span datasrc= "#dsoData" datafld= "City"
