Parameterized Composite Key

RP1629548713 — Fri, 15 Nov 2024 23:41:46 GMT

Hi ,

I Would like to pass a composite key to my job through a single context variable.

I don't wish anyone to go in the job and make changes within the component..

My target is thbaseoutput and I would like to pass only one context parameter within the custom row key which will pick its value whether single or composite through context only .

Can you all please assist?

To use context variable, simply input expression context.varName in the custom row key field. Can you try and let me know whether the component supports context variable or not.

Regards

Shong

Hi Shong,

When I passed just context.varname it gives an error of row length is 0 .

And when I pass it as row1+"."+context.varname it is taking all the rows as keys.

You could simply create a json formatted string in the context variable and read the various information within the child job.
