MySQL选择重复的列

Question

我在select语句中选择了State和Zip3两列,准确说明了我想看到的内容.当我在原生MySQL中执行此操作时,我得到了正确的结果:

SELECT State,Zip3, FirstName, LastName, State, Zip3 
FROM Person
WHERE State >= 'A'
ORDER BY State, Zip3
LIMIT 10;

+-------+------+-----------+-------------+-------+------+
| State | Zip3 | FirstName | LastName    | State | Zip3 |
+-------+------+-----------+-------------+-------+------+
| AB    | T7X  | Adalei    | Starreveld  | AB    | T7X  |
| AK    | 998  | Linda     | Rosenthal   | AK    | 998  |
| AL    | 361  | Benjamin  | Sung        | AL    | 361  |
| AL    | 362  | Lawrence  | Kallus      | AL    | 362  |
| AZ    | 857  | Rose      | Springfield | AZ    | 857  |
| CA    | 941  | Maura     | Cronin      | CA    | 941  |
| CA    | 941  | Dov       | Grunschlag  | CA    | 941  |
| CA    | 943  | Ruth      | Hodos       | CA    | 943  |

| CT    | 064  | DEBORAH   | GRASER      | CT    | 064  |
+-------+------+-----------+-------------+-------+------+

当我在Cold Fusion中执行此操作时,我得到了错误的结果:

<cfquery name = "stest" datasource = "Moxart">
select State,Zip3, FirstName,LastName,State,Zip3 from Person
where State >= 'A'
order by State,Zip3
</cfquery>
<cfset j = 0>
<table>
<cfoutput query = "stest">
<tr>
<cfloop index = "col" list = "#columnlist#">
<cfset j = j + 1>
<cfset colname[j] = #stest[col][currentrow]#>
<td>   #colname[j]# </td>
</cfloop><br/>
</tr>
</cfoutput>
</table>

如何从ColdFusion中获得正确的结果.我正在使用ColdFusion 8和Firefox.

Answer 1

尝试为列添加别名

select 
  State,
  Zip3, 
  FirstName,
  LastName,
  State AS State_2,
  Zip3 as Zip3_2 
from 
  Person
where 
  State >= 'A'
order by 
  State,
  Zip3
