TALEND set a context variable depending from TalendDate

Question

I want to set a context variable depending from a TalendDate routine in the "value as Table" tab which would allow me to select the day of yesterday : TalendDate.formatDate("yyyy-MM-dd", TalendDate.addDate(TalendDate.getCurrentDate(),-1,"dd"))

It does not work, I do not have any returns when I include in the selection as date('"+context.date+"').

Could you please tell me what I am missing ? I would be very grateful if you could help me with that.

Answer 1

You should create a global variable, then in a tJava assign a value to it.

Or according to your current situation, in tJava paste the following:

context.date = TalendDate.formatDate("yyyy-MM-dd", TalendDate.addDate(TalendDate.getCurrentDate(),-1,"dd"));

Then you can use your variable. It won't be a java Date type, but a string.

Answer 2

You can use the tContextLoad component to create key value pairs of contexts to be used in your job or child jobs.

In your case you would want to use a tFixedFlowInput component to specify what you wanted (or this could be any input really but this is just a way of hard coding it directly to the job without needing an external resource) and then link that to the tContextLoad component with a schema of key and value like so:

You'll want to use your original code snippet as the value in your tFixedFlowInput component:

In the first screenshot above I've also added a tContextDump component and connected it to a tLogRow so you can see the available contexts to the job:
