array question

Recommended Posts

I have a database called 'people'. It has a table 'record'. It contains 4 fields : Name, Address, Phone-Number, Pan-Number.

The page exp1.php has the following code

<html>

<head>

  <meta http-equiv="Expires" content="0">

  <title>experiment</title>

</head>

<body bgcolor="#ffffff" leftmargin="100" topmargin="100" marginwidth="100" marginheight="100">

<?php

 

$my_connection = mysql_connect('localhost', 'root', '');

 

if (!$my_connection)

{

  die('Could not conncet: ' . mysql_error());

}

 

echo 'Connected Successfully' . '<br><br>';

 

$my_database = mysql_select_db('people');

 

if (!$my_database)

{

  die('Could not find database: ' . mysql_error());

}

 

$query = "SELECT * FROM record";

$result = mysql_query($query);

$my_rows = " ";

 

while($row = mysql_fetch_array($result, MYSQL_ASSOC))

{

  $my_rows = $my_rows . "Name : {$row['Name']} <br>"  . "Address : {$row['Address']} <br>" . "Phone_Number : {$row['Phone-Number']} <br>" . "Pan_Number : {$row['Pan-Number']} <br><br>";

}

 

echo ($my_rows);

 

 

 

 

 

 

mysql_close($my_connection);

 

?>

 

</body>

</html>

 

It has an output as follows:

 

Connected Successfully

 

Name : Sanjib Sinha

Address : 55

Phone_Number : 332225648

Pan_Number : 123456

 

Name : Kaberi sinha

Address : 55

Phone_Number : 123456

Pan_Number : 123456

 

Name : Hagudu Mutudu

Address : 55

Phone_Number : 123456

Pan_Number : 123456

 

Name : D N chowdhury

Address : 55, Regent Park, Calcutta-711109

Phone_Number : 123456

Pan_Number : 123456

 

So it works fine. Now I want to retrieve only the 'Name' fields. What should be the code?

SELECT Name FROM record;

 

That should be your query.

 

Yes that has solved the problem. I also tried in a different way,

I just put

$query = "SELECT * FROM record";

$result = mysql_query($query);

$my_rows = " ";

 

while($row = mysql_fetch_array($result, MYSQL_ASSOC))

{

  $my_rows = $my_rows . "Name : {$row['Name']} <br>";

}

 

echo ($my_rows);

It also reads only 'Name' from record.

Thank you for answering.

That will indeed work but if you're only wanting the name field, that is all you should select (rather than selecting all fields, which * does). Selecting more fields than you need is inefficient.

 

Sorry, I should not have thought that way. I just tried to manage as my knowledge is incomplete. Thanks. I'm learning.
