It's possible. Although, the results may not be what you expect. Post the query and the error.
I'm trying to do a select query with a left join and regular join and keep getting a mysql error. Is this even possible?

$row = mysql_fetch_array($result);

I want to join my law table to my troubleticket table, my trouble ticket table is the main table.

$query = 'SELECT TT_number, datetimeend, service, MINUTE(datetimestart) AS startminute, HOUR(datetimestart) AS starthour, DAYOFMONTH(datetimestart) AS startday, MONTH(datetimestart) AS startmonth, YEAR(datetimestart) AS startyear, category, status, priority.order, priority, description, datetimestart FROM troubleticket, priority, category, services WHERE TT_number="'.$tt.'" LEFT JOIN troubleticket ON lawid=law.lawid AND troubleticket.pid=priority.pid AND troubleticket.catid=category.catid AND services.sid=troubleticket.sid '; $result = mysql_query($query) or die($query."<br />\n".mysql_error());

ok i moved the where clause to the end of the query and it still doesn't work.. Do i need to declare my law table in the from clause before declaring the join?

SELECT col1, col2 ... FROM table1 INNER JOIN table2 ON table1.col = table2.col INNER JOIN table3 ON table2.col = table3.col LEFT JOIN table4 ON table3.col = table4.col ... ... WHERE ...
If you're still having trouble post the query you're currently using in addition to the error shown when you use the method shown in the earlier post to make the mysql_query call.
