Sql server 更新未添加正确的值

我的select语句返回我正确加入的表中的ID 393，从92开始，上升到484，它不是PK字段，因此当我总共需要更新550行时，一些ID可以被多次使用，当我运行更新时，它只为所有550行将数字92添加到表中

update movements set [location] = locaID.id FROM (
SELECT
      lo.id
  FROM [Harvest_Transactions] ht
  left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
  left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id 
  left join [batches] b on b.name = hms.Batch_id
  left join [phases] p on p.batch = b.id and p.[type] = 3
  left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and lo.Bay_id = gt.Bay_id
  where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05 09:33:00.000' OR hms.CreatedOn is null )
 )locaID where product = 14

我遗漏了什么，所以它会用正确的值进行更新？

我对您的查询的第一印象是，只有移动表中product=14的行会用子查询中的单个值进行更新

如果要基于另一个派生表更新值，则需要某种方式将行链接在一起，即要更新的表与保存其他数据的表之间的连接请参见

动作和动作之间的共同点是什么

SELECT
  lo.id
 FROM [Harvest_Transactions] ht
 left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
 left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id 
 left join [batches] b on b.name = hms.Batch_id
 left join [phases] p on p.batch = b.id and p.[type] = 3
 left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and 
 lo.Bay_id = gt.Bay_id
 where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05 
 09:33:00.000' OR hms.CreatedOn is null )

我认为粗略的语法应该是

UPDATE movements
set [location] = locaID.id 
FROM movements
JOIN (
SELECT
  lo.id
 FROM [Harvest_Transactions] ht
 left join [Harvest_Master_Shift] hms on ht.Harvest_Master_id = hms.Harvest_Master_id
 left join [Greenhouse_Troughs] gt on ht.Trough = gt.Greenhouse_Trough_id 
 left join [batches] b on b.name = hms.Batch_id
 left join [phases] p on p.batch = b.id and p.[type] = 3
 left join #loc lo on lo.name = gt.Trough_No and lo.area = gt.SQM_per_Trough and 
 lo.Bay_id = gt.Bay_id
 where ht.Number_of_Plants_Harvested != 0 and (hms.CreatedOn <= '2020-02-05 
 09:33:00.000' OR hms.CreatedOn is null )
) locaID
ON movements.<some column> = locaID.<some column>

您正在使用SQL Server吗？或者Postgres？我正在SQL Server中运行更新脚本，但正在将数据推送到Postgres，将SQL切换到Postgres值得将其添加到问题中以澄清。您缺少SELECT just after=运算符和beforelocaID@Mohamad除非我想将其转换为另一个子查询，否则select在此不起作用。我已调整了查询，取代了92填充点，现在为空。你调整了什么？您是否实现了移动和派生表之间的连接？
