several variables in several places in the graph?


New member
Is it possible to define several variables which would be used in several places in the graph?

Yes of course.
This kind of variable is called "global parameters".
You can define them here:

...and then they are available everywhere: that is: they are available:
* in the calculator or the rowFilter directly
* in all other fields of all other boxes using the special character ">".

Afterwards, to initialize these "global parameters" according to the "context" when a graph starts, all you have to do is use the "getParametersFromFiles" box (to be connected in the first place to the "runToFinishLine" box). This allows having several environments: a dev environment, another prod environment, another "at home" environment, etc.

These same "global parameters" also allow you to do:
* curls,
* to define file names dynamically (eg: with a date or with a "global path")
* to configure the ODBC/OleDB connection parameters,
* to conditionally execute a sub-part of the graph
* etc.

You will find more details on "global parameters" in sections 5.1.5., 5.1.1., 5.21.10, 5.21.6., 10.12., 4.7.1.
