Declaring MySQL variable in Dataflow

Is it possible to declare a global variable in MySQL Dataflow?

What I am trying to do is declare a variable in one transformation and call that variable in a different transformation

 

Here's an example of what I am trying to do: 

 

Transformation1(SQL - No Output)   

 

SET @testvar = 1; 

 

Transformation2 (Table) -

SELECT * FROM test_table WHERE some_column = @testvar

 

This doesn't seem to work. @testvaris just null in this case.

  • As far as I know, variables are not supported in Domo's MySQL dataflow.

     

    As a possible solution though....you could have one transform output a table that just has the value you are trying to store, and the access that table in another transform.

     

    That might not work as effectively as I see it in my head, as it depends a bit on your dataflow structure.

    Although it's been a while since this was addressed, for the sake of others searching for an answer to the same question, there is a way to do this. A detailed thread about this can be found at the Dojo post below:
