SQL查询，以显示在同一行同一ID，但其自身的UF场

Question

令我在statments查询有一个线，但根据不同的UF场，以显示与同一BT_ID所有数据的工作。例如，我有多个具有相同BT_ID的订单，并且需要在其自己的UF字段中显示每个Invoice_reference编号。 但是我没有把所有的数据都传到我的UF字段。许多领域都认为不可空白。任何帮助appriciated，谢谢：

Answer 1

显然这个查询是相当复杂的，我想这是为什么你还没有的任何答案了。这里有一些红旗，（a）几乎不可能理解查询的内容，（b）建议使用完全不同的方法进行完全重写。

其中警告标志：

1. 在GROUP BY子句中19场的任何查询已经失去了沿线地方道路。
2. 有内蒙古一个大杂烩连接和左连接（见下面的讨论）
3. 大量使用复制和粘贴的
4. 格式/行缩进的是一个烂摊子

首先，对左侧的连接：

1. 您已经包括LEFT JOIN到在引用的表（Org_Control）WHERE子句......由于该表必须有一个值，以便通过WHERE条件， LEFT JOIN什么都不加。
2. 您在名称表中包含了一个LEFT JOIN，该表中加入了BT_ID，它是列排列的主要驱动程序。实际上查询中的行可能不匹配正在连接的表之间的行吗？

接下来，作为整体的方法来查询：

在SQL Server中，我觉得击穿最清晰的方式这样成可管理的，可以理解的，可测试块臃肿的庞然大物与通用表表达式（热膨胀系数）。有关CTE的引物，请参阅http://www.4guysfromrolla.com/webtech/071906-1.shtml。

而且，有可能是最简单的方法做你want--什么从结果集到columns--转换数据的行与数据透视表（见http://blogs.msdn.com/b/spike/archive/2009/03/03/pivot-tables-in-sql-server-a-simple-sample.aspx）

随着这两个积木的地方，让你要去的地方的方式是这样的：

• 从小开始，试验件（在这种情况下，内部跨和发票之间的连接），
• 然后建立与查找数据，如Name和Name_Address一旦你知道核心提供了你想要的数据。

为您的查询，一个可行的框架可能是这个样子：

; WITH RowNumberedTrans AS (
    SELECT 
    INVOICE_REFERENCE_NUM, INVOICE_CHARGES, INVOICE_CREDITS, TRANSACTION_DATE, POSTED, 
    ROW_NUMBER() OVER(PARTITION BY BT_ID ORDER BY BT_ID) AS rk 
    FROM Trans 
), UFLabeledTrans AS (
    SELECT 
    CASE rk 
     WHEN 1 THEN 'UF6' 
     WHEN 2 THEN 'UF7' 
     -- etc 
    END AS UFLabel, 
    -- other fields 
    FROM RowNumberedTrans 
), TransactionsPerInvoice AS (
    SELECT 
    (
     '<td>' + 
     cast(Invoice.REFERENCE_NUM as varchar(10)) + '</td>' + 
     cast(Invoice.DESCRIPTION as varchar(50)) + '</td>' + '$' + 
     cast(Trans.INVOICE_CHARGES as varchar) +'</td>' 
    ) AS UFValue, 
    -- other fields 
    FROM Invoice i 
    INNER JOIN UFLabledTrans t ON i.REFERENCE_NUM = t.INVOICE 
), InvoiceInfoInColumns AS (
    -- logic here to: 
    -- * select from TransactionsPerInvoice 
    -- * construct your pivot table spreading out UFValues computed above 
    -- * do any grouping (should be on one or two fields at most) 
    -- * etc. 
), NameAddressLookup AS (
    -- INNER JOIN between Name and Name_Address 
) 
SELECT -- long list of columns 
FROM TransactionsPerInvoice tpi 
    (LEFT? INNER?) JOIN NameAddressLookup nl ON tpi.BT_ID = nl.ID 

运气好;希望这足以让你开始正确的方向。
