MYSQL Query Help

I am attempting to write an mysql query where I pull information from 2 tables based on certain parameters. I have the following query working as I need it to:

"SELECT * FROM masterlist, masterupload WHERE UID=uploadID AND masterlist.client='ClientName' ORDER BY entry ASC"

What I need to add to this query is a condition that will return exactly what is stated above, OR all entries from masterlist where client="ClientName", without the condition that UID=uploadID as there will be cases where an entry exists in masterlist without a matching entry in masterupload. Make sense? I don't know if I need to do some type of JOIN to accomplish this, but would appreciate the help. Thanks!

First of all: Please use the JOIN syntax and table alias names to increase readability. The problem is where is UID coming from?

I guess it's a LEFT JOIN you need:

SELECT 	L.*,
	U.*
FROM 	masterlist L
	LEFT JOIN masterupload U ON L.UID = U.uploadID
WHERE 	L.client = 'ClientName' 
ORDER BY L.entry ASC;

Sorry, it should read masterlist.UID=masterupload.uploadID.

I tried your suggested query and get an error.
