我可以用MySQL加入COUNT嗎？

Question

這是我的數據

newCatCols 
===== 
id  sku  name 
--------------- 
1   4001 Black 
2   4031 Red 
3   4021 Black 
4   4041 Blush 

products 
===== 
id  sku  Price 
--------------- 
1   4001 123 
2   4031 232 
3   4021 453 
4   4041 233 

這是我的查詢

SELECT COUNT(*) AS numTotal 
FROM `products` 
INNER JOIN `colors` ON `products`.`sku` = `colors`.`sku` 
WHERE (
`name` = 'Apple_Black' 
OR `name` = 'Black' 
OR `name` = 'Black_Aubergine' 
OR `name` = 'Black_Blush' 
OR `name` = 'Black_Slate' 
OR `name` = 'Black_Turquoise' 
OR `name` = 'Red_Black' 
OR `name` = 'Sapphire_Black' 
OR `name` = 'Multi Apple' 
) 
AND `status` = '1' 
AND `category` = 'sig' 
GROUP BY `products`.`sku` 
ORDER BY `products`.`rank` ASC 

理想的情況下，如果我只是改變這一行是完美SELECT COUNT(*) AS numTotal不知何故只修改，使其工作？數據當前返回行值爲1的產品列表，因此它只是循環而不計算所有行的總值。

這是應只顯示在返回總數，4例如應顯示

Output 
===== 
numTotal 
--------------- 
4

這將返回符合條件的獨特產品SKU的數量：

SELECT COUNT(distinct `products`.`sku`) AS numTotal 
FROM `products` 
INNER JOIN `colors` ON `products`.`sku` = `colors`.`sku` 
WHERE `name` in ('Apple_Black' 
     ,'Black' 
     ,'Black_Aubergine' 
     ,'Black_Blush' 
     ,'Black_Slate' 
     ,'Black_Turquoise' 
     ,'Red_Black' 
     ,'Sapphire_Black' 
     ,'Multi Apple' 
    ) 
    AND `status` = '1' 
    AND `category` = 'sig'
