Failure in data acquisition for a custom data source type (csv)

[RoiBeci]

Hi All,

I was following the How-To Video for creating a custom data source type using csv file, and it was working fine, until I've deleted manually al data from the table, and now i'm getting the following error:

Incorrect Integer Value:'??' for column 'id' at row 1

The csv file is delimited with TABs and starting with "/N" just like the example file in the video.

Any ideas please?

 

Thanks

Can you try resetting the schema. That will remove all previous data.

@ The csv file is delimited with TABs and starting with "/N" just like the example file in the video.

It should be \N and not /N at the begnning of a row in CSV files. So make this change, reset the scheme if you want and try to acquire again.

Hi,

It was a typo, the CSV file starts with "\N".

I've also tried to reset the sceme but it aint worked.

Here is the content of my csv file (called "vsm_issues.csv"):

\N	fas3070-1.ps.lab	court1	fas3070-2	court1	destination volume too small; it must be equal to or larger than the source volume	144.22:06:56
\N	fas3070-1.ps.lab	court2	fas3070-2	court2	destination volume too small; it must be equal to or larger than the source volume	144.22:06:56
\N	10.68.65.14	vol4	fas3070-2	vol4	destination volume too small; it must be equal to or larger than the source volume	7.23:55:45

 I appreciate your help.

Roi,

    I was able to use data contents you provided and acquistion worked for me. So nothing wrong with the data in the csv file. You said you manually deleted/edited the CSV files, right? What was the editor you used? What is the Encoding setting for it? I think that is what has caused this. Looks like your editor uses Encoding : UCS-2 Big Endian or Little Endian or something else. 

 The error like: Incorrect Integer Value:'??' for column 'id' at row 1 or Incorrect integer value: 'N' for column 'id' at row 1 etc. indicate that the CSV file has incorrect Encoding. The correct encoding required is : UTF-8 without BOM ( Byte Order Mark ) or ANSI.

Now to fix it, You can use a text editor like Notepad++ open this CSV file and From Tab button Encoding-> Convert to UTF-8 without BOM. Save the file and acquire again. I think this will work. You can use other editors too, but you need to do the same thing i.e. change the Encoding type. Or send me the file by email and I'll return u with the fix.

warm regards,

SINHAA,

That was it!

I was creating this csv file using powershell script. Now I need to convert the output file to UTF-8 without BOM.

Thanks!

Rio,

     You can create CSV files using powershell too without the need to convert the result file into UTF-8 without BOM. You need to use -Encoding Byte option. Somthing like this below code example.

$UserFile = "./Users2.csv"
New-Item -Path $UserFile -type file -Force

Add-Content $UserFile ([Byte[]][Char[]] "`\N`tabhi`tsinhaa`n") -Encoding Byte

Add-Content $UserFile ([Byte[]][Char[]] "`\N`t$first_name`t$last_name`n") -Encoding Byte

thanks you I really appreciate your help 🙂

How can I actually import UTF8 characters into the database using this technique? I'm trying to build a data source for active directory. We have a lots of users and  groups having scandinavian characters in their names and I have yet to find a way how to import those.

If I use -Encoding Byte it obviously fails and if I try to use -Encoding UTF-8 I get all sorts of errors like "Incorrect integer value: 'N' for column 'id' at row 1" or "Incorrect integer value: '500' for column 'id' at row 1" depending if I have \N or a numeric id in the first field of the file.

@eino

It took me many failures like you are facing  before I've figured out a way to get this done. I've tried with Danish, Sweedish and Latin letters and they all get acquired fine. 

Wait till tomorrow, I'll post it with details along with an example.

Its night time in my country and I had a long day.

Can you post some examples of such words you would like to acquire? I'm trying to give sample code based on some real world names.

@sinhaa

Thanks for taking a look into this. Some example words: Järvinen, ylläpito, käyttäjähallinta, henkilökunta. I hope you see the letters correctly?

Excellent, thank you! I'll have to upgrade to 4.0RC1.

Alternatively, I would like to drop this DB from the MySQL WFA server, but when i'm trying to drop the table I'm getting "access denied" message.

I am using TOAD for mysql explorer, and connected to "localhost" using wfa\Wfa123.

Is there a root user for the mysql WFA Server which can drop my custom made DB?

Roi.

[sinhaa]

This user wfa\Wfa123 doesn't have permission to drop a database. 

So if you want to drop this database/schema , you need to delete the dictionary from WFA UI.
