Question

我有两张桌子。

这是结构

CREATE TABLE IF NOT EXISTS `CATALOG_CATEGORY_PRODUCT` 
  ( 
     `CATEGORY_ID` INT(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'Category ID', 
     `PRODUCT_ID`  INT(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'Product ID', 
     `POSITION`    INT(11) NOT NULL DEFAULT '0' COMMENT 'Position', 
     PRIMARY KEY (`CATEGORY_ID`, `PRODUCT_ID`), 
     KEY `IDX_CATALOG_CATEGORY_PRODUCT_PRODUCT_ID` (`PRODUCT_ID`) 
  ) 
ENGINE=INNODB 
DEFAULT CHARSET=UTF8 
COMMENT='Catalog Product To Category Linkage Table'; 

CREATE TABLE IF NOT EXISTS `CATALOG_PRODUCT_ENTITY_TIER_PRICE` 
  ( 
     `VALUE_ID`          INT(11) NOT NULL AUTO_INCREMENT COMMENT 'Value ID', 
     `ENTITY_ID`         INT(10) UNSIGNED NOT NULL DEFAULT '0' COMMENT 
     'Entity ID', 
     `ALL_GROUPS`        SMALLINT(5) UNSIGNED NOT NULL DEFAULT '1' COMMENT 
     'Is Applicable To All Customer Groups', 
     `CUSTOMER_GROUP_ID` SMALLINT(5) UNSIGNED NOT NULL DEFAULT '0' COMMENT 
     'Customer Group ID', 
     `QTY`               DECIMAL(12, 4) NOT NULL DEFAULT '1.0000' COMMENT 'QTY', 
     `VALUE`             DECIMAL(12, 4) NOT NULL DEFAULT '0.0000' COMMENT 
     'Value', 
     `WEBSITE_ID`        SMALLINT(5) UNSIGNED NOT NULL COMMENT 'Website ID', 
     PRIMARY KEY (`VALUE_ID`) 
  ) 
ENGINE=INNODB 
DEFAULT CHARSET=UTF8 
COMMENT='Catalog Product Tier Price Attribute Backend Table';

我使用了以下查询

SELECT * FROM `catalog_product_entity_tier_price` LEFT OUTER JOIN catalog_category_product ON catalog_product_entity_tier_price.entity_id = catalog_category_product.product_id WHERE catalog_category_product.category_id = 57 AND catalog_product_entity_tier_price.qty = 500.0000

它返回了97行。我想删除那97行。

所以我使用了这个查询。

DELETE FROM `catalog_product_entity_tier_price` LEFT OUTER JOIN catalog_category_product WHERE catalog_product_entity_tier_price.entity_id = catalog_category_product.product_id AND catalog_category_product.category_id = 57 AND catalog_product_entity_tier_price.qty = 500.0000

但是我收到了这个错误。

#1064 - 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 'LEFT OUTER JOIN catalog_category_product WHERE catalog_product_entity_tier_price' at line 1

有人能告诉我正确的语法吗？

谢谢

试试这个::

    DELETE cpet 
FROM `catalog_product_entity_tier_price` cpet 
LEFT OUTER JOIN catalog_category_product ccp
ON
cpet.entity_id = ccp.product_id 
AND ccp.category_id = 57 
WHERE cpet.qty = 500.0000

使用查询删除mysql中的行
