TOS 7.2 problem with SCD component with special characters on Type2

Anonymous — Wed, 29 Jan 2020 15:30:04 GMT

Hi,

I'm using TOS 7.2 and trying to configure a SCD component with source and destination MSSQL.

I ran the job a first time in order to create the new datas in my destination table. It worked fine.

After that I ran the job a second time with the same source and I was expecting to have 0 new line in my destination table. But I had some...

It appears that some fields contain some "special characters" like 'Â', 'Ã', 'Œ','¬'. These characters are invisible in the datatable, but when I read it in ANSI, I can see them.

It looks like the SCD component doesn't manage properly this kind of characters, and create a new line, even if there is any change.

exemple:

In my datatable: 'CHN'

In ANSI: 'CHÂNÂ'

I found some topic about this point, but the solution is not working in my case.

My question: How can I configure my job so that the SCD component manage it properly?

Thank You.

I may be misunderstanding your issue here, but it sounds to me like the SCD components are doing the correct thing. If your data is different, even by a single bit, a new record should be created in a SCD. I think you need to consider cleaning your data before attempting to add it to the SCD.

As I said, I may have misunderstood. If so, please let me know where

Regards

Richard

Hello rhall_2_0,

Thank you for your answer.

The data in the source doesn't change.

1st step :

Data source with special characters

Data destination -> empty

-> The job create a new line in the destination that corresponds to the source

2nd step

Data source same as 1st step

Data destination same as Data source

-> The job create another new line in the destination that corresponds to the source and Update the line of the 1st step

The problem (I think) is that the data contains some special characters, and I read on a forum that it can make the SCD component not work fine.

I'm going to look how I can clean the datas before attempting to add it to the SCD.

Thank you

Do you have the Data Frabric product or are you using the Open Source edition? If you have Data Fabric, I would recommend speaking to support about this so that you can demonstrate it to them. This could be a bug. Otherwise, would you mind maybe raising this here: https://jira.talendforge.org/
