2- Check for duplicate URL keys

FROM catalog_product_flat_1
GROUP BY url_key HAVING ( COUNT(url_key) > 1 );

3- Check for dupes in products’ names
-------------------------------------

SELECT name,
COUNT(name) AS NumOccurrences
FROM catalog_product_flat_1
GROUP BY name HAVING ( COUNT(name) > 1 );


4 - Check for dupes in  customer_entity_varchar 
-----------------------------------------------

SELECT entity_id, attribut_id
COUNT(entity_id) AS NumOccurrences
FROM customer_entity_varchar 
GROUP BY name HAVING ( COUNT(name) > 1 );


select   entity_id,
         attribut_id,
         count(*)
from     customer_entity_varchar
group by entity_id,
         attribut_id
having   count(*) > 1


SELECT cp.category_id
FROM catalog_category_product cp
LEFT JOIN catalog_category_entity c ON cp.category_id = c.entity_id
WHERE ISNULL( c.entity_id )


SELECT DISTINCT(cp.product_id)
FROM `catalog_category_product` cp
LEFT JOIN catalog_product_entity p ON cp.product_id = p.entity_id
WHERE ISNULL( p.entity_id )
