MySQL的 - 选择都哪里去数组值

Question

我有这个表：

ID | Product_ID | Filter_ID 
1   1     8 
2   1     9 
3   2     10 

我也有PHP数组包含过滤器进行检查：

$arr = (8,9,10); 

现在，如何确保PRODUCT_ID（ 1）有$ arr中的所有过滤器？

Answer 1

如果只希望里面有所有3个filter_ids那些PRODUCT_ID，试试这个：

$sql = "SELECT COUNT(*) AS total, Product_ID FROM `test`.`test` WHERE Filter_ID IN (".implode(', ', $arr).") GROUP BY Product_ID HAVING total >= ". sizeof($arr);

@edit

如果你只需要知道，如果具体的Product_ID都有3个Filter_IDS：

$sql = "SELECT COUNT(*) AS total, Product_ID FROM `test`.`test` WHERE Filter_ID IN (".implode(', ', $arr).") and Product_ID = 1 GROUP BY Product_ID HAVING total >= ". sizeof($arr); 

Answer 2

$arr = [8, 9, 10]; 
$sql = "SELECT * FROM `Table` WHERE `Filter_ID` IN (".implode(', ', $arr).")";
