Read and Write to the Same CSV file Possible ?

[GheZaide]

 

if i read and write to the same filename it is giving 0 rows

but if i write on a new file it's working

UseCase: csv1 = holds the initial value Date >>> after run the csv1 should have the updated value Current RunDate

if i disable the tFileOutput for the meantime i am seeing the expected value

or if i assign it to a new file

Hi

The tFileOutputDelimited will create an empty file with the same file name before the file is read, that's why 0 rows are read from the file, about the code generation model, you can refer to this page on Talend Help Center.

As a workaround, cache the data into memory and read the data back in next subjob, eg:

tFileInputDelimited--tJavaRow--tHashOutput

|onsubjobok

tHashInput--main--tFileOutputDelimited.
