Question

这是我的第一个问题。我刚从前任IT人那里接过了SQL报告，而且我正在努力解决下面的问题。它突然停止工作两天前，现在显示：

报告处理期间发生错误。（rsProcessingAborted）数据集＆＃39; DataSet1＆＃39;的查询执行失败。（rsErrorExecutingCommand）子查询返回的值超过1。当子查询遵循=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或子查询用作表达式时，不允许这样做。声明已经终止。

它停在第49行：

and (select t.[status] from [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t left join [ksimakeprod01].[imake].dbo.WORKORDER wa on t.WorkOrderKey=wa.WORKORDERKEY where wa.workorderno=wh.WorkOrderNo)<>7

我从错误中了解到我尝试更新包含多行数据的列...但是此查询之前有效...我该如何解决？

Answer 1

和（从[ksimakeprod01]中选择t。[status]。[imake] .dbo.iSchWOScheduleLine t left join [ksimakeprod01]。[imake] .dbo.WORKORDER wa on t.WorkOrderKey = wa.WORKORDERKEY where wa.workorderno = wh.WorkOrderNo）LT;大于7

问题是查询现在返回多行。如果您自己运行查询，那将是显而易见的。解决此问题的最简单方法是确保使用TOP子句只返回1行，如下所示。

and (select TOP 1 t.[status] from [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t left join [ksimakeprod01].[imake].dbo.WORKORDER wa on t.WorkOrderKey=wa.WORKORDERKEY where wa.workorderno=wh.WorkOrderNo)<>7

您应该知道这是一个“错误”修复，因为它可能导致整个查询返回错误的数据。可以这样考虑...你正在检查状态列是否为7.但是，由于查询返回多行，一个状态值可能是7而另一个可能是7以外的其他值。因为你是现在使用顶部子句，顶行可以是7，或者顶行可以是另一个值。

我不想这么说，但修复此查询的最佳方法是完全重写。这是确保您的查询做得正确的唯一方法。

Answer 2

如果完成：

(select 
    t.[status] 
from 
    [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t 
left join 
    [ksimakeprod01].[imake].dbo.WORKORDER wa 
on 
    t.WorkOrderKey=wa.WORKORDERKEY 
where 
    wa.workorderno=wh.WorkOrderNo)<>7

然后问题是此子查询返回多个记录，因此您无法将其与单个值进行比较。您可以强制它使用TOP 1返回一个值，但这取决于该上下文是否合适。如果你使用它，你基本上会忽略该查询中的所有其他值，并选择第一个出现的值可能没有意义！

(select 
    TOP 1 t.[status] 
from 
    [ksimakeprod01].[imake].dbo.iSchWOScheduleLine t 
left join 
    [ksimakeprod01].[imake].dbo.WORKORDER wa 
on 
    t.WorkOrderKey=wa.WORKORDERKEY 
where 
    wa.workorderno=wh.WorkOrderNo)<>7

STATEMENT ERROR（子查询返回的值超过1）
