 /**
 *	@todo Rewrite this to use ARUpdateFilter or simply an SQL query to update all values
 
 		As in the original bug report:
 
 			The update query for merging value 799 into 808 would look something like this:
 
 			UPDATE SpecificationItem
 			LEFT JOIN SpecificationItem AS SecondItem ON SpecificationItem.productID=SecondItem.productID AND SecondItem.specFieldValueID=808
 			SET SpecificationItem.specFieldValueID=808
 			WHERE SpecificationItem.specFieldValueID=799 AND SecondItem.specFieldValueID IS NULL
 
 			- it would only update products that do not have value 808 already set (otherwise the query would error because of duplicate SpecificationItem records).
 
 			The remaining records with value 799 will be automatically removed (cascade) when SpecFieldValue 799 is deleted.
