A client mentioned that he kept having to reindex the Product Flat Data but the notification in the admin section never went away. While trying to reindex from command line I was greeted with the following error:

Turns out this problem was caused by products which were deleted but still existed in the product flat data table.
To find these products you can run this query:
|
0
1
2
3
|
SELECT pf1.entity_id
FROM catalog_product_flat_1 pf1
LEFT JOIN catalog_product_entity p ON pf1.entity_id = p.entity_id
WHERE ISNULL( p.entity_id )
|
In this case it was nearly 80 products! To fix it you can just delete them with this query:
|
0
1
2
3
|
DELETE pf1.*
FROM catalog_product_flat_1 pf1
LEFT JOIN catalog_product_entity p ON pf1.entity_id = p.entity_id
WHERE ISNULL( p.entity_id )
