mysql_db_query

Send a MySQL query (PHP 4, PHP 5, PECL mysql:1.0)
resource mysql_db_query ( string database, string query [, resource link_identifier] )

mysql_db_query() selects a database, and executes a query on it.

Parameters

database: The name of the database that will be selected.
query: The MySQL query.
link_identifier: The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning is generated.

Return Values

Returns a positive MySQL result resource to the query result, or FALSE on error. The function also returns TRUE/FALSE for INSERT/UPDATE/DELETE queries to indicate success/failure.

ChangeLog

Version	Description
4.0.6	This function is deprecated, do not use this function. Use mysql_select_db() and mysql_query() instead.

<?php

if (!$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) {

    echo 'Could not connect to mysql';

    exit;

}


if (!mysql_select_db('mysql_dbname', $link)) {

    echo 'Could not select database';

    exit;

}

$sql    = 'SELECT foo FROM bar WHERE id = 42';
$result = mysql_query($sql, $link);


if (!$result) {

    echo "DB Error, could not query the database\n";

    echo 'MySQL Error: ' . mysql_error();

    exit;

}


while ($row = mysql_fetch_assoc($result)) {

    echo $row['foo'];

}

mysql_free_result($result);

?>

Notes

Note:

Be aware that this function does NOT switch back to the database you were connected before. In other words, you can't use this function to temporarily run a sql query on another database, you would have to manually switch back. Users are strongly encouraged to use the database.table syntax in their sql queries or mysql_select_db() instead of this function.
