添加到长而复杂的查询

Question

我有一个问题

Select 
cards.card_id, 
  cards.item_name, 
  cards.meta_description,
  cards.description, 
  '' as Weight,
  '' as UPC,
  '' as Part,
  cards.seo_keywords,
  concat('',cards.card_id,'_shadow.png') AS ImageURL,
  lookup_details.value,
  concat('ARTIST - ', card_import.artist) AS Brand,
 replace(lower(concat( 'http://www.test.com/', pcat.seoname,'/',cat.seoname, '/', cards.seoname, '.htm' )),' ','+') AS link,
            concat(pcat.name,' > ',cat.name) as Merchant,
 round(min(card_lookup_values.card_price), 2) AS 'price',
 min(cast(lookup_details.value as signed)) as 'quantity'

FROM
  cards
  left join card_import on card_import.card_id = cards.card_id
  join card_lookup_values on card_lookup_values.card_id = cards.card_id
           INNER JOIN card_categories cc ON cards.card_id = cc.card_id AND cards.card_live = 'y' AND cards.active = 'y' AND cc.active = 'Y'
          INNER JOIN categories cat ON cat.category_id = cc.category_id AND cat.active = 'Y'
          INNER JOIN categories pcat ON cat.parent_category_id = pcat.category_id
INNER JOIN card_lookup_values as card_values ON cards.card_id = card_values.card_id
INNER JOIN lookup_details ON card_lookup_values.lookup_detail_id = lookup_details.lookup_detail_id

WHERE card_lookup_values.lookup_id = 7,lookup_details.lookup_id= 40
GROUP BY
  cards.card_id
ORDER BY
  cards.card_id

我想我所有的设置都是正确的，但在Navicat中我一直收到一个错误，说我有一个错误接近**

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'lookup_details.lookup_id= 40
GROUP BY
  cards.card_id
ORDER BY
  cards.card_' at line 28

**

我是不是漏掉了什么？

Answer 1

您希望将WHERE条件中的AND或or (以合适的为准)放在一起。

...
WHERE card_lookup_values.lookup_id = 7 AND lookup_details.lookup_id= 40
...

...
WHERE card_lookup_values.lookup_id = 7 OR lookup_details.lookup_id= 40
...

Answer 2

您有一个额外的逗号

WHERE card_lookup_values.lookup_id = 7,lookup_details.lookup_id= 40

应该是

WHERE card_lookup_values.lookup_id = 7 AND lookup_details.lookup_id= 40

Answer 3

正确的SQL语法在WHERE子句中使用AND关键字。

WHERE blahblah = blah AND trala = la
