顺序按升序排列

Question

我已经使用了POPUP LOV心尖

select VEN_INVOICE_REFNO as display_value, VEN_INVOICE_REFNO as return_value 
    from VENDORINVOICE 
order by 1 asc; 

我想给我看的值下面的查询显示在数字顺序，即按升序order.i图已经尝试了所有的可能的方式，我知道但它不起作用。

Answer 1

它似乎是所在领域的数据类型为字符串，将其转换成数字，然后应用order by

select CAST(VEN_INVOICE_REFNO AS INTEGER) as display_value, VEN_INVOICE_REFNO as return_value 
from VENDORINVOICE 
order by 1 asc; 

Answer 2

试试这个::

select VEN_INVOICE_REFNO as display_value, VEN_INVOICE_REFNO as return_value 
    from VENDORINVOICE 
order by ORDER BY CAST(`display_value` AS SIGNED) 

Answer 3

我记得我有这个问题一次，我最终乘以1

类似的东西（不知道是否会工作，你可能需要投下您它VEN_INVOICE_REFNO到数字）

select (VEN_INVOICE_REFNO * 1) as display_value, VEN_INVOICE_REFNO as return_value 
    from VENDORINVOICE 
order by 1 asc; 

像这样

：

select CONVERT((VEN_INVOICE_REFNO * 1),UNSIGNED INTEGER) as display_value, VEN_INVOICE_REFNO as return_value 
    from VENDORINVOICE 
order by 1 asc; 

Answer 4

试试这个

选择VEN_INVOICE_REFNO作为display_value，VEN_INVOICE_REFNO作为return_value 来自VENDORINVOICE order by VEN_INVOICE_REFNO

级

Answer 5

另外这里的解决方案将无法正常工作，如果任何的记录有一个非数字值，所以FWIW这里是一个替代的解决方案：

select VEN_INVOICE_REFNO as display_value, VEN_INVOICE_REFNO as return_value 
from VENDORINVOICE 
order by LPAD(VEN_INVOICE_REFNO,100,' ') asc; 

只要改变100到列的最大尺寸。

但是，如果列中有任何负数或小数（浮点数）值，我的解决方案将不起作用。
