IBMi (AS400) fans only * How to import a CSV file into db2

By -





#IBMiSample

Let's try with a very simple csv like this, called file1.csv:


Code;Name

3741;Joe
3742;Barth
3810;
3945;



First of all we need to save file1.csv into ISF.
In my PUB400 (free AS400 at pub400.com) I have this directory:
/home/PALDO

I copy file1.csv to /home/PALDO

Use standard FTP transfer software (I use WinScp, I think Filezilla will work too)












Let's take a look inside my directory





I type WRKLNK and I verify the existence of File1.csv





It looks as expected:





To import this file I need a similar table on DB2.
In my example it means that I will create a table with a decimal field and a charachter field.




I create the table TEMPCSV (PALDO1 is my Library):







CREATE TABLE PALDO1.TEMPCSV (
CLCCL0 DECIMAL(7, 0) DEFAULT 0 ,
CLNOM0 CHAR(50) DEFAULT ' ' )
RCDFMT FMTXX


Here's my new table TEMPCSV:







The table TEMPCSV is now created and it is empty:





We can optionally set up a source file to note lines not imported by the CPYFRMIMPF command. In my opinion it is very useful.

Type
CRTSRCPF FILE(PALDO1/IMPERRORS) MBR(IMPERR) TEXT('Errors CPYFRMIMPF')
to create a source file. PALDO1 is my Library.



To fill TEMPCSV with File1.csv data we will use CPYFRMIMPF command:



Type:
CPYFRMIMPF FROMSTMF('/home/PALDO/File1.csv') TOFILE(PALDO1/TEMPCSV) MBROPT(*REPLACE) RCDDLM(*CRLF) FLDDLM(';') ERRRCDFILE(PALDO1/QCLSRC IMPERR) ERRRCDOPT(*REPLACE) RMVCOLNAM(*YES)


Let's take a look at the TEMPCSV table:


SELECT * FROM TEMPCSV






Let's check the error file:




IMPERR file is empty, it means no errors, it means all lines have been imported.

That's it.


I appreciate all the comments made on this blog.

(IBM i fans only) Efficient WRKSPLF with WSF - How to Search string into spooled files, Sort, and Generate PDFs on IBMi

Searching Spooled Files Made Easy: A Unique Solution Managing spooled files efficiently is crucial for users dealing with numerous rows of print data. IBM's WRKSPLF command provides a standard way to interact with spooled files, but it lacks certain features that can significantly enhance user experience. In this article, we'll delve into a powerful functionality that IBM doesn't offer — the ability to search among spooled file lists. Our goal is to highlight the advantages of this capability and introduce a practical solution. The Limitations of Standard WRKSPLF While the WRKSPLF command is a handy tool for working with spooled files, it falls short in certain aspects. One prominent limitation is the inability to search efficiently through the list of spooled file rows. Users often find it challenging to quickly locate specific files based on criteria like creation date, status, or content. Introducing a Unique Solution: WSF (WorkSpooledFiles) To address the limitations of...

(IBM i fans only) Detecting and Handling Non-Printable Characters in DB2 SQL Using LOCATE() and REPLACE() Functions

By -

When working with DB2 SQL on the IBMi platform, one of the challenges we might encounter is dealing with non-printable characters in our data. These are characters that don't have a direct representation on a standard keyboard and can cause display programs to crash if not handled properly. For this example, we'll be working with the CLANA00F file, which contains customer data. You can find details on how to create this file on my blog post here . Non-printable characters can sneak into our records for various reasons, and to prevent issues, we can run an SQL query that uses the LOCATE() function. This function returns the position of the first occurrence of a substring within a string, allowing us to detect these problematic characters. Suppose we have a customer name with a non-printable character, specifically the EBCDIC '0D' character, which corresponds to the "Carriage Return" (CR) control character in ASCII. To find this character in our records, we can ...

(IBM i fans only) How to Sniff User Access

If you need to monitor user access on your IBM i system, you can use SQL to query the history log. Note: At the end of this post, you'll find a request directly addressed to you, the readers. Here’s a simple example of how you can do this: SELECT MESSAGE_ID,        MESSAGE_TIMESTAMP,        FROM_USER,        MESSAGE_TEXT     FROM TABLE (             QSYS2.HISTORY_LOG_INFO()         )     WHERE message_id IN ('CPF1164', 'CPF1124')           AND FROM_USER IN ('QSECOFR', 'QSYS', 'QSYSOPR')     ORDER BY MESSAGE_TIMESTAMP In this query: - QSYS2.HISTORY_LOG_INFO(): This function retrieves information from the history log. -  message_id IN ('CPF1164', 'CPF1124') : Filters the results to include only specific message IDs, which indicate sign-on and sign-off events. - FROM_USER in ('QSECOFR', 'QSYS', 'QSYSOPR'): Filters the resu...
