sql - 按升序排列

Question

我在 Apex 中对 POPUP LOV 使用了以下查询

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

我想按数字顺序（即按升序）向我显示图中所示的值。我已经尝试了我知道的所有可能的方法，但它不起作用。

Answer 1

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 2

您的字段数据类型似乎是字符串，将其转换为数字然后应用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 3

我记得我曾经遇到过这个问题，我最终将它乘以 1

类似的东西（不确定它是否会起作用，您可能需要将 VEN_INVOICE_REFNO 转换为数字）

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

如果任何记录具有非数字值，则此处的其他解决方案将不起作用，因此此处的 FWIW 是另一种解决方案：

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

只需更改100为列的最大大小即可。

但是，如果列有任何负数或小数（浮点）数值，我的解决方案将不起作用。

Answer 5

试试这个

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