Context Variable

Anonymous — Thu, 03 Jan 2019 08:44:52 GMT

HI Team,

I am having a doubt in passing value to context variable.

I am having a context variable named "I_From" which is of string type and i am giving dafault value as "2018-01-01"

Also Using the Implecit tContextLoad setting and am giving the filepath in which a file is placed.

In that file also am passing some values to the context variables, One of the context variable in that file is the same "I_From" .

My doubt is for the same variable the value is passed from file and also the default value assigned in context view,which value will be taken whether from file or value assigned in Context view.

NOTE: I checked the above scenario, for me it is taking the value from file eventhough it is assigned in context view, if the variable is not present in file then only the value from context view is taken.

Please clarify the above scenario.

Thanks-

Gayathri S

Hi Gayathri,

The default values which you are assigning in the context view will be always replaced by the new values you are giving using Context load or through other components like tjava,tjavarow etc.

The value in the context view will be assigned during the starting of a Talend Job. But during any point, if the value is being replaced by any means, the new value assigned in between your program will be the value for your context variable.

Throughout the program if you are not modifying the value, the the original value in context view will be still available for usage.

Hope I have answered your query 🙂

Warm Regards,
