数据窗口查询不遵守 ORDER BY 子句

Question

我正在开发一个表格，以便获得用于采购目的的订单。

我在主窗体中有一个数据窗口作为报表对象。此数据窗口（子报表）有一个 select 来检索该订单的订单行。除 ORDER BY 子句外，一切正常。我需要按订单行号 (orderline.orderlineno) 降序对订单行进行排序。

我已经通过 Sybase Central > Interactive SQL 尝试了 SQL 语句，它以所需的顺序显示记录，但是当在我的应用程序中使用该表单时，它会显示记录按 orderline.forcompid 排序。很奇怪

我的 SQL 语句中是否有任何错误或 Power Builder 中我遗漏的其他内容？

ORDER BY 1 ASC

Answer 1

按照步骤..

首先为 select 语句中的列指定别名..因为它的联合别名应该在所有查询中匹配。
将外部 select 与别名放在一起，并使用您需要的列的别名进行排序。

**请记住，order by 会影响执行时间..

看下面的示例

SELECT  LineNo,
        LineName,   
        Unit,   
        QTY,   
         .......

FROM

( SELECT 
         A.orderlineno AS LineNo,   
         A.name as LineName ,   
         A.unitid AS Unit,   
         A.quantity As Qty,   
         ...........

    FROM orderline A,   
         componenttype B,   
         componentunit C,   
         workorder D 
   WHERE ( C.comptypeid = B.comptypeid ) and  
         ( C.compid = A.forcompid ) and  
         ( A.workorderid = D.workorderid ) and 
         ( A.orderid = 40003774 ) AND  
         ( A.status = 1 ) AND
         ( A.includeonform <> 0 ) 
union
  SELECT 
         A1.orderlineno AS LineNo,   
         A1.name as LineName ,   
         A1.unitid AS Unit,   
         A1.quantity As Qty,   
        .........

    FROM orderline A1,   
         componenttype B1,   
         componentunit C1  
   WHERE A1.workorderid IS NULL AND
         ( C1.comptypeid = B1.comptypeid ) and  
         ( C1.compid = A1.forcompid ) and  
         ( A1.orderid = 40003774 ) AND  
         ( A1.status = 1 ) AND
         ( A1.includeonform <> 0 ) 

union
  ........
) AS t1

ORDER BY LineNo ASC

Answer 2

你的 SQL 很好。还不如在工会上取消订单。在数据窗口本身中设置排序顺序。将要排序的列拖到右侧并取消选中升序框。这总是覆盖 SQL 排序。

数据窗口查询不遵守 ORDER BY 子句

Datawindow query is not respecting ORDER BY clause

sql

powerbuilder

sybase

datawindow

sql-order-by
