I have to CSV file in input (input1, input2) and i want to compare all rows of both CSV and extract rows with lines with differences of the input1 in another CSV file (Both CSV have the same number of lines)
I try with tMap but finally it doesn't works (or i don't know how to make with this ^^).
Is there a component to make it easy?
Should work with tMap but you need to map each field from input1 with corresponding one in imput2.
Not so easy when there is too much fields.
You also caculate a MD5 key with all fields then you just have to compare the key and the MD5 result between input1 and input2.
Less easy than solution 1, but works well when you have a lot of fields.
See this link where I post a reply using an other nickname (I was unable to retrieve my password). It speaks about salesforce, but don't care, it's the same with text file.
Indeed I have about twenty fields its risk to be complicated...
I thank you I will try with the MD5, I would have thought that a module allowing to make its easily exist on Talend...
