] | You can only count the columns that have a value.
Also if the entity\_id is a numeric field you need to remove the quotes.
For example:
```
SELECT MIN(min_price) AS base_price,entity_id
FROM catalog_product_index_price
WHERE entity_id IN (31439, 31440, 31441, 31442, 31443, 31444, 31445, 31446, 31447, 31448, 31469 ... | ```
SELECT MIN(min_price) AS base_price,entity_id
FROM catalog_product_index_price
WHERE entity_id IN
('31439,31440,31441,31442,31443,31444,31445,31446,31447,31448,31469,31470,31471,
31472,31473')
AND min_price is not null;
