Removing quotes from an INT column allows MySQL to use the index and this can reduce rows scanned by __99.997 percent__. Example from Magento 1.12 on a production database; the query takes nearly a second to execute:

```sql
mysql> explain DELETE FROM `catalog_product_index_price` WHERE entity_id IN('433284', 433283)\G;
*************************** 1. row ***************************
           id: 1
  select_type: SIMPLE
        table: catalog_product_index_price
         type: ALL
possible_keys: NULL
          key: NULL
      key_len: NULL
          ref: NULL
         rows: 773625
        Extra: Using where
1 row in set (0.00 sec)
```

This query is much faster:

```sql
mysql> explain DELETE FROM `catalog_product_index_price` WHERE entity_id IN(433284, 433283)\G;
*************************** 1. row ***************************
           id: 1
  select_type: SIMPLE
        table: catalog_product_index_price
         type: range
possible_keys: PRIMARY,IDX_CATALOGPRODUCTINDEXPRICE_ENTITYID
          key: PRIMARY
      key_len: 4
          ref: NULL
         rows: 19
        Extra: Using where
1 row in set (0.00 sec)
```

Incorrectly quoting both INT values produces the same result:

```sql
mysql> explain DELETE FROM `catalog_product_index_price` WHERE entity_id IN('433284', '433283')\G;
*************************** 1. row ***************************
           id: 1
  select_type: SIMPLE
        table: catalog_product_index_price
         type: range
possible_keys: PRIMARY,IDX_CATALOGPRODUCTINDEXPRICE_ENTITYID
          key: PRIMARY
      key_len: 4
          ref: NULL
         rows: 19
        Extra: Using where
1 row in set (0.00 sec)
```
