Sql 如何更新与其他表联接的表中的列？

我想用其他表的引用更新表的两列。执行脚本时显示错误

错误：从命令第1行开始的错误：

UPDATE wb_costing_work_items,
       sa_sales_documents,
       sa_sales_document_items
   SET cwi_price_per_hour = sdi_price,
       cwi_amount = sdi_price * cwi_hours
 WHERE cwi_lo_id = sad_lo_id
   AND sdi_sad_id = sad_id
   AND sdi_wit_id = cwi_wit_id
   AND cwi_id = 1650833

命令行错误：1列：28错误报告：SQL错误：ORA-00971: 缺少集合关键字 97100000-“缺少集合关键字”

SQL语句

UPDATE wb_costing_work_items cwi,
       sa_sales_documents sad, 
       sa_sales_document_items sdi
   SET cwi.cwi_price_per_hour = sdi.sdi_price,
       cwi.cwi_amount = sdi.sdi_price * cwi.cwi_hours
 WHERE cwi.cwi_lo_id = sad.sad_lo_id
   AND sdi.sdi_sad_id = sad.sad_id
   AND sdi.sdi_wit_id = cwi.cwi_wit_id
   AND cwi.cwi_id = 1650855

也许是这样的

注意，我不得不对哪个列属于哪个表进行一些猜测，因为您没有包含任何关于表定义方式的信息

所以很可能我没有正确理解，您需要根据实际的表结构调整查询

merge into wb_costing_work_items  
using 
(
    select cwi.pk_column,  -- don't know what the PK of the wb_costing_work_items is due to lack of information
           sdi.sdi_price,  -- don't know if this column really belong to this table
           sdi.sdi_price * cwi.cwi_hours as total-- again unsure about column names due to lack of information
    FROM wb_costing_work_items cwi
      JOIN sa_sales_documents sad ON sad.sad_lo_id = cwi.cwi_lo_id -- not sure about these, due to lack of information
      JOIN sa_sales_document_items sdi 
        ON sdi.sad_id = sad.sdi_sad_id     -- not sure about these, due to lack of information
       AND sdi.sdi_wit_id = cwi.cwi_wit_id -- not sure about these, due to lack of information

) t ON (t.pk_column = w.pk_column) -- not sure about this, due to lack of information
when matched then 
 update 
    set cwi_price_per_hour = t.sdi_price,
        cwi_amount = t.total;

这肯定行得通

            UPDATE (SELECT cwi_price_per_hour,
                           sdi_price,
                           cwi_amount,
                           sdi_price,
                           cwi_hours
                      FROM wb_costing_work_items,
                           sa_sales_documents,
                           sa_sales_document_items
                     WHERE     cwi_lo_id = sad_lo_id
                           AND sdi_sad_id = sad_id
                           AND sdi_wit_id = cwi_wit_id
                           AND cwi_id = 1650833)
               SET cwi_price_per_hour = sdi_price, cwi_amount = sdi_price * cwi_hours

请为使用的表加上别名，并为列加上前缀，以便轻松阅读您的查询

这肯定行得通

            UPDATE (SELECT cwi_price_per_hour,
                           sdi_price,
                           cwi_amount,
                           sdi_price,
                           cwi_hours
                      FROM wb_costing_work_items,
                           sa_sales_documents,
                           sa_sales_document_items
                     WHERE     cwi_lo_id = sad_lo_id
                           AND sdi_sad_id = sad_id
                           AND sdi_wit_id = cwi_wit_id
                           AND cwi_id = 1650833)
               SET cwi_price_per_hour = sdi_price, cwi_amount = sdi_price * cwi_hours
