Axapta 在查询中混合临时表和实表

为什么这些查询中的一个有效，而另一个无效？我编写了工作查询，然后将表设为临时表，必须重写该表才能使临时表位于外部

这是表中的数据：

tmpTASItemQtyInventDim:

|ItemId | InventDimId | InventQty | |-------|--------------|-----------| |73016 | Dim 11542913 | 0 | |Sales Id |Line No | ItemId | InventDimId | SalesQty | |------------|--------|--------|--------------|-----------| |SO120036796 | 1| 73016 | Dim 11542913 | 2 |

select firstonly tmpTASItemQtyInventDim
    join itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId == 'SO120036796'  &&
          tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
          tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
          tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (tmpTASItemQtyInventDim.ItemId)
    info("Insufficient Qty");
else
    info("Good qty");

select firstonly itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId     == 'SO120036796'
    exists join tmpTASItemQtyInventDim
        where tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
              tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
              tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (salesLine.ItemId)
    info("Insufficient Qty");
else
    info("Good Qty");

|ItemId | InventDimId | InventQty| |-------|--------------|-----------| |73016 |尺寸11542913 | 0| 销售线：

|ItemId | InventDimId | InventQty | |-------|--------------|-----------| |73016 | Dim 11542913 | 0 | |Sales Id |Line No | ItemId | InventDimId | SalesQty | |------------|--------|--------|--------------|-----------| |SO120036796 | 1| 73016 | Dim 11542913 | 2 |

select firstonly tmpTASItemQtyInventDim
    join itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId == 'SO120036796'  &&
          tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
          tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
          tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (tmpTASItemQtyInventDim.ItemId)
    info("Insufficient Qty");
else
    info("Good qty");

select firstonly itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId     == 'SO120036796'
    exists join tmpTASItemQtyInventDim
        where tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
              tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
              tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (salesLine.ItemId)
    info("Insufficient Qty");
else
    info("Good Qty");

|销售标识|行号|项目标识|库存|销售数量| |------------|--------|--------|--------------|-----------| |SO120036796 | 1 | 73016 |尺寸11542913 | 2| 不起作用：

|ItemId | InventDimId | InventQty | |-------|--------------|-----------| |73016 | Dim 11542913 | 0 | |Sales Id |Line No | ItemId | InventDimId | SalesQty | |------------|--------|--------|--------------|-----------| |SO120036796 | 1| 73016 | Dim 11542913 | 2 |

select firstonly tmpTASItemQtyInventDim
    join itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId == 'SO120036796'  &&
          tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
          tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
          tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (tmpTASItemQtyInventDim.ItemId)
    info("Insufficient Qty");
else
    info("Good qty");

select firstonly itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId     == 'SO120036796'
    exists join tmpTASItemQtyInventDim
        where tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
              tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
              tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (salesLine.ItemId)
    info("Insufficient Qty");
else
    info("Good Qty");

仅选择第一个tmpTASItemQtyInventDim
从salesLine连接itemId、InventDimId、sum（salesQty）
按项目ID、InventDimId分组
其中salesLine.SalesId=='SO120036796'&&
tmpTASItemQtyInventDim.ItemId==salesLine.ItemId&&
tmpTASItemQtyInventDim.InventDimId==salesLine.InventDimId&&
tmpTASItemQtyInventDim.InventQty

有效：

|ItemId | InventDimId | InventQty | |-------|--------------|-----------| |73016 | Dim 11542913 | 0 | |Sales Id |Line No | ItemId | InventDimId | SalesQty | |------------|--------|--------|--------------|-----------| |SO120036796 | 1| 73016 | Dim 11542913 | 2 |

select firstonly tmpTASItemQtyInventDim
    join itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId == 'SO120036796'  &&
          tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
          tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
          tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (tmpTASItemQtyInventDim.ItemId)
    info("Insufficient Qty");
else
    info("Good qty");

select firstonly itemId, InventDimId, sum(salesQty) from salesLine
    group by itemId, InventDimId
    where salesLine.SalesId     == 'SO120036796'
    exists join tmpTASItemQtyInventDim
        where tmpTASItemQtyInventDim.ItemId == salesLine.ItemId     &&
              tmpTASItemQtyInventDim.InventDimId    == salesLine.InventDimId    &&
              tmpTASItemQtyInventDim.InventQty      < salesLine.SalesQty;

if (salesLine.ItemId)
    info("Insufficient Qty");
else
    info("Good Qty");

从salesLine中选择firstonly itemId、InventDimId、sum（salesQty）
按项目ID、InventDimId分组
其中salesLine.SalesId=='SO120036796'
存在加入tmpTASItemQtyInventDim
其中，tmpTASItemQtyInventDim.ItemId==salesLine.ItemId&&
tmpTASItemQtyInventDim.InventDimId==salesLine.InventDimId&&
tmpTASItemQtyInventDim.InventQty

---

两者都应该输出

不足的数量

，但第一个从内存中说

好的数量

，我认为您也需要在第一个表上分组 看见

选择firstonly项目ID，InventDimId
从tmpTASItemQtyInventDim
按项目ID、InventDimId分组
join itemId、InventDimId、sum（salesQty）
来自销售线
按项目ID、InventDimId分组
其中salesLine.SalesId=='SO120036796'&&
tmpTASItemQtyInventDim.ItemId==salesLine.ItemId&&
tmpTASItemQtyInventDim.InventDimId==salesLine.InventDimId&&
tmpTASItemQtyInventDim.InventQty

混合临时表和真实表就像在鹅卵石路上骑自行车。你并不总是得到你认为你得到的东西，而且

在AX 2012中，您可以使用工作更可预测的TempDB

非常有趣的帖子。有时我应该使用trace parcer，并真正检查我的查询成本，我认为。太棒了！不完全理解为什么我需要这样做，但它是有效的。我认为这是因为没有group by的查询相当于

code

Select SalesLine.ItemId，TmptSiteMQTyInventDim的SalesLine.InventDimId从TmptSiteMQTyInventDim.ItemId==SalesLine.ItemId和TmptSiteMQTyInventDim.InventDimId==SalesLine.InventDimId…..

code

如果“您的不工作是”测试SalesLine.ItemId，它认为会产生正确的结果
