Q: Is it possible to reset/clear a variable's value in the data library?

Mitch Dale

Hey @Product,

Is there any way to reset or clear a variable that's in the data library?

I have a use case where I'm looping through a json array, and for some loop iterations, there'll be certain variables that are not empty, and some that are empty. My concern is that if I have a loop execution where a certain variable is not empty, and then the next iteration that variable is empty, the variable value from the previous iteration is preserved - please correct me if that's wrong.

I can't use a copy content WA since the actual value field is mandatory, and I tried using a 'Retrieve values from json' WA as well but that didn't work.

Mitch Dale We actually just released a new Wrk Action which might help with this. It is called Update Data Library Item(s) to empty. It sets selected Data Library items to empty values/defaults by type: text becomes '', numbers become 0, and booleans become false.

Basically, you just add the values you want to clear to the fields to capture, and the Wrk Action will set the value.

Hey Mitch,

No, there is no way to clear a value at this time. Typically in the situation that you are mentioning we reccomend using a placeholder value instead of a blank value. for example, at the end of each loop set all the values for $EMPTY or something similar and then after you've pulled the values you can do a check to see if it's still $EMPTY.

This works nicely if there are only a couple of values but if there are a lot of values that need to be reset let me know and we can come up with a more elegant solution.
