How to run this mysql query - php

Question

I am trying to load all records from the database that have been created by the current logged on user in Joomla, im not sure if its possible to have php inside a mysql query though ?, if not how would I go about doing this otherwise ?
SELECT
leadname,
businessname,
postcode,
gasoiluser,
dervuser,
kerouser,
cf_uid,
cf_id
FROM
#__chronoforms_data_addupdatelead
WHERE createdby = '<?php
$user =& JFactory::getUser(); echo $user->get('name') ; ?>'
ORDER BY cf_created DESC

Answer 1

Of course you can access PHP variables for creating the query - as the #__ prefix suggests, you're already running your query from "inside Joomla". Which means it is in php, and something like this should do what you want:
$user =& JFactory::getUser();
$db =& JFactory::getDBO();
if (!$user->guest) {
$query = 'SELECT leadname, businessname, postcode, gasoiluser, '.
' dervuser, kerouser, cf_uid, cf_id '.
' FROM #__chronoforms_data_addupdatelead '.
' WHERE createdby = '.$db->Quote($user->name)).
' ORDER BY cf_created DESC';
$db->setQuery($query);
}
But a little more context would help us see what you'll have to do exactly - what's the code around the SQL query - is it in a php file?
Remember, echo prints to the Response, which is not what you want to do in this case, you want to change the query; so just concatenate the variable content to your query, as shown above; and you should actually be already be in php mode where this query is defined, so the <?php tag is of no use (but again, too few context to be sure about this)!

Answer 2

mysql is a database server that accepts a string and returns either result set or an error
string passed to mysql must be proper SQL statement
what you have in your question is not proper SQL statement, it is a string waiting to be parsed by PHP and whoever knows by who else
this part is PHP for sure:
<?php $user =& JFactory::getUser(); echo $user->get('name') ; ?>
this part is something like a placeholder for correct table name that is replaced at runtime of whatever you got this query from(supposedly joomla):
#__chronoforms_data_addupdatelead
if you want to run that query you must to figure out what to substitute with the aforementioned blocks
