使用 IBM iSeries Client Access 从 AS400 db 文件创建 .CSV 文件时，我可以挤出前导空格吗？

Question

I have a very simple iseries AS400 DDS file defined in this way

A    R U110055R                  TEXT('POSITIVE PAY') 
A            ACCT55   9A 
A            SERL55        10A 
A            ISSD55        10A 
A            AMT55         13A 
A            NAME55        50A

I am using Data Transfer from System i (IBM I Access for Windows V6R1) to output a csv to the desktop. It will then be used by our banking PC software. I cannot find a setting or a file type that will yield the data without leading blanks. It consistently holds the file sizes of the Database file (without trailing blanks).

I need:

  "192345678","311","07/22/2016","417700","ALICE BROWN CO."
  "192345678","2887","07/22/2016","4124781","BARBIE LLC."
  "192345678","2888","07/22/2016","4766","ROBERT BLUE, INC."
  "192345678","2889","07/22/2016","71521","NANCYS COOKIES, INC"
  "192345678","312","07/22/2016","67041","FRANKS MARKET"

But I get:

 "192345678","       311","07/22/2016","     11417700","ALICE BROWN CO."
 "192345678","       887","07/22/2016","      4124781","BARBIE LLC." 
 "192345678","       888","07/22/2016","      3204766","ROBERT BLUE, INC." 
 "192345678","       301","07/22/2016","      2971521","NANCY, INC" 
 "192345678","       890","07/22/2016","       967041","FRANKS MARKET"

Answer 1

DDS的限制：

Use of TRIM in DDS

The answer seems to be "You can't." If I were doing this, I'd probably create a SQL VIEW with a DDL statement rather than try to get it done with DDS.

解决方法： (W3School) or (IBM Knowledge Center)

CREATE VIEW U110055V1 as
    SELECT  TRIM(ACCT55),
            TRIM(SERL55),
            TRIM(ISSD55),
            TRIM(AMT55),
            TRIM(NAME55)
    FROM U110055
    RCDFMT U110055V1R;

建议:

将新创建的视图导出到.CSV 文件(refer here or here)
在网络上共享 IFS 文件以实现轻松一致的自动访问，（无需使用 i Access 手动导出）。

Answer 2

Data Transfer from IBM i 应用程序的 Data Options 按钮会弹出一个 window，您可以在其中明确指定用于提取的 SQL 语句数据.

您可以在那里使用 SQL TRIM() 函数...
