mysql查詢沒有篩選和按預期

我有下面列出的查詢，它是從一個PDO語句。除了collectionId = 3部分之外，查詢中的所有內容都可以正常工作。它與其他整數的返回結果...mysql查詢沒有篩選和按預期

我盯着這一段時間，不能發現什麼是錯的，這一切對我來說都很好嗎？

SELECT `Hat`.`id` AS `Hat_id` , `Hat`.`hatCode` AS `Hat_hatCode` , `Hat`.`hatCodeOther` AS `Hat_hatCodeOther` , `Hat`.`name` AS `Hat_name` , `Hat`.`description` AS `Hat_description` , `Hat`.`colorId` AS `Hat_colorId` , `Hat`.`collectionId` AS `Hat_collectionId` , `Hat`.`mainPicture` AS `Hat_mainPicture` , `Hat`.`subPicture` AS `Hat_subPicture` , `Hat`.`type` AS `Hat_type` , `Hat`.`featured` AS `Hat_featured` , `Hat`.`published` AS `Hat_published` , `Hat`.`deleted` AS `Hat_deleted` 
FROM `modx_hats` AS `Hat` 
WHERE (
`Hat`.`published` =1 
AND `Hat`.`collectionId` = '3' 
AND `Hat`.`colorId` LIKE '%||2||%' 
OR `Hat`.`colorId` LIKE '2||%' 
OR `Hat`.`colorId` LIKE '%||2' 
OR `Hat`.`colorId` LIKE '2' 
) 
LIMIT 0 , 30

你OR條件需要在括號：

SELECT `Hat`.`id` AS `Hat_id` , `Hat`.`hatCode` AS `Hat_hatCode` , `Hat`.`hatCodeOther` AS `Hat_hatCodeOther` , `Hat`.`name` AS `Hat_name` , `Hat`.`description` AS `Hat_description` , `Hat`.`colorId` AS `Hat_colorId` , `Hat`.`collectionId` AS `Hat_collectionId` , `Hat`.`mainPicture` AS `Hat_mainPicture` , `Hat`.`subPicture` AS `Hat_subPicture` , `Hat`.`type` AS `Hat_type` , `Hat`.`featured` AS `Hat_featured` , `Hat`.`published` AS `Hat_published` , `Hat`.`deleted` AS `Hat_deleted` 
FROM `modx_hats` AS `Hat` 
WHERE (
`Hat`.`published` =1 
AND `Hat`.`collectionId` = '3' 
AND (`Hat`.`colorId` LIKE '%||2||%' 
OR `Hat`.`colorId` LIKE '2||%' 
OR `Hat`.`colorId` LIKE '%||2' 
OR `Hat`.`colorId` LIKE '2') 
) 
LIMIT 0 , 30

這就是它 - 謝謝，因爲這是第一個正確的答案，我會接受這一點，當我被允許。將upvote所有其他雖然:) –

你可以試試這個，新增()爲或分組

WHERE (
`Hat`.`published` =1 
AND `Hat`.`collectionId` = '3' 
AND (`Hat`.`colorId` LIKE '%||2||%' 
OR `Hat`.`colorId` LIKE '2||%' 
OR `Hat`.`colorId` LIKE '%||2' 
OR `Hat`.`colorId` LIKE '2' 
) 
)

你不」請指定您想要過濾的內容，但您的問題很可能是情況t的評估與您的想法不同 - 您如何評估OR和AND（沒有括號將它們分組）？

目前的情況是，該查詢返回一個滿足所有記錄無論是

`Hat`.`published` =1 AND 
`Hat`.`collectionId` = '3' AND 
`Hat`.`colorId` LIKE '%||2||%' `

OR其履行其中的任何其他限制：

OR `Hat`.`colorId` LIKE '2||%' 
OR `Hat`.`colorId` LIKE '%||2' 
OR `Hat`.`colorId` LIKE '2'

這是設置括號權的所有問題。我的猜測是你想要發佈所有記錄= 1，collectionId = 3和你給出的一個colorIds。對於這一點，你必須組會相應：

WHERE (
`Hat`.`published` =1 
AND `Hat`.`collectionId` = '3' 
AND 
    (
    `Hat`.`colorId` LIKE '%||2||%' 
    OR `Hat`.`colorId` LIKE '2||%' 
    OR `Hat`.`colorId` LIKE '%||2' 
    OR `Hat`.`colorId` LIKE '2' 
) 
)
