Select rows with 00

I have this SQL Query

Code:

SELECT *
FROM cards
WHERE (cards.worth =2
AND cards.deny =0)
AND NOT
EXISTS (

SELECT alttext
FROM user_inventory
WHERE cards.alttext = user_inventory.alttext
AND user_inventory.name = '".$person."'
) ORDER BY RAND() LIMIT 1

Which works fine, but if a person has a card blank in the inventory (blank urls have 00.png in the end, ie: http://midnighttempest.com/images/cards/final00.png) it doesn't pick those up, and i'm not sure how to change it so that it does. If i add a

Code:

OR user_inventory LIKE '%00.png'

into the second select then it doesn't pick anything up at all.

How do i need to change it?

From what I see , user_inventory is a table name. You have to use the column name that contains the url in the LIKE clause.

I have the query working, but is there anyway to make it better since its quite long

Code:

SELECT *
FROM cards
WHERE (
cards.worth =2
AND cards.deny =0
)
AND NOT
EXISTS (

SELECT alttext
FROM user_inventory
WHERE cards.alttext = user_inventory.alttext
AND user_inventory.name = 'Desbrina'
AND user_inventory.worth =2
)
OR EXISTS (

SELECT alttext
FROM user_inventory
WHERE (
cards.alttext = user_inventory.alttext
AND user_inventory.url LIKE '%00.png'
)
AND user_inventory.name = 'Desbrina'
AND user_inventory.worth =2
)
ORDER BY RAND( ) 
LIMIT 1
