Question

这是我的选择查询，工作正常：

   SELECT PRICE.PRICEDATETO AS PDF
    ,ATTR.PRICEDATEFROM AS ADF
    ,ATTR.PRICEDATETO AS ADT 
    FROM RT_DATA_CORE DCORE 
       INNER JOIN RT_DATA_PRICE PRICE ON DCORE.ID=PRICE.ID 
       INNER JOIN RT_PRODUCT_CORE PCORE ON PCORE.ID=PRICE.PRODUCTID 
       INNER JOIN RT_DATA_PRICEATTRIBUTES ATTR ON        
              CONCAT(ATTR.PRODUCTID,'_V')=PCORE.SKU 
          AND PRICE.ID='PRICE-26095657' 
          AND ATTR.PRICEDATETO>NOW() 
   ORDER BY ATTR.PRICEDATETO ASC LIMIT 1;

我需要将其更新为ADF = PDF

我正在尝试这个给我一个错误：

的MySQL＆GT; UPDATE RT_DATA_PRICE PRICE INNER JOIN（选择PA.PRICEDATETO作为DATER，PCORE.ID作为PID来自RT_DATA_PRICEATTRIBUTES PA，RT_PRODUCT_CORE PCORE，其中PA.PRICEDATETO＆gt; NOW（）和PCORE.SKU = CONCAT（PA.PRODUCTID，'_ V'）ORDER BY PA.PRICEDATETO ASC限制1）AOP.OPD = PRICE.PRODUCTID和PRICE.ID ='PRICE-26095657'Set AOP.DATER = PRICE.PRICEDATETO; 错误1288（HY000）：UPDATE的目标表AOP不可更新

表格RT_DATA_CORE未被使用，因此我已将其删除，请尝试此操作

UPDATE RT_DATA_PRICE PRICE, RT_PRODUCT_CORE PCORE, RT_DATA_PRICEATTRIBUTES ATTR
SET ATTR.PRICEDATEFROM = PRICE.PRICEDATETO 
WHERE
    PCORE.ID=PRICE.PRODUCTID 
    CONCAT(ATTR.PRODUCTID,'_V')=PCORE.SKU 
    AND PRICE.ID='PRICE-26095657' 
    AND ATTR.PRICEDATETO>NOW();

更新子查询不工作的mysql
