  • Welcome @huda_tt. Can you try to give a bit more detail about what is happening? Could you include examples? When you say "it always returns" can you say what "it" is? Where are you trying to get the filename from? In which component?

  • hi @Screwtape I want to extract the current filename first in the "tdatabaseinput" to make the query {"SELECT processedfile.NOM FROM processedfile WHERE NAME = '" + ((String) globalMap.get ("tFileList_1_CURRENT_FILE")) + "'" } if it does not already exist I want to insert it (current file name) in the mysqltable "prossedfile" using "tfixedflowinput" but the value inserted is always the same ~$B.xlsx

  • The link between tFileLink_1 and tFixedFlowInput_1 is not iterating - it will only pick up the (first/last?) iteration. Try running your subjob from a "run if" from the "disponibilite_3g" component, or even the map component.

  • Hi! The way in which we would normally use Stack Overflow would be that this post would have been a comment on my answer, rather than another answer. I can't see what has caused your null-pointer exception without seeing a lot of detail from your project. Can you show a picture of your project as you have it now, and I'll see if I can guess where the issue is.

I think the issue you have is that your "RunIf" link is before the iterator, and therefore it's not being triggered at the right time.



The image below shows a simplified version, where I list the rows in the spreadsheets and then the file names. If I connected the second subjob to the tFileList_1 component, as you did in the question, I only get the logs from tLogRow_1 and the last filename by tLogRow_2.



Talend Job Example



With the link as shown, behind the iterator, then I get spreadsheet contents listed and then the title of it:



Col1|Col2|Col3
A|B|C
D|E|F
A.xlsx
Col1|Col2|Col3
A|B|C
D|E|F
B.xlsx
