Data Distiller - scheduled query based on the result of previous scheduled query

[Michael_Soprano]

Assume that I would like to have multiple scheduled queries:

- Query 1

- Query 2

- Query 3. 

Is it possible to set up scheduled queries like that:

Query 1 runs -> then -> Query 2 is run and is based on the result of the Query 1 ->  Query 3 runs and is based on the result of Query 2

Hi @Michael_Soprano ,

I do not think you cant create that sort of dependency within AEP query service.

However, if this is your goal, I would suggest:

1. Easiest option: put everything in a single query. The whole script will be divided into 3 blocks where each block will check the previous block's success status (you have to keep log may be in a separate dataset) and only proceed then
2. Lengthy process: you can use middleware instead of a single query. The 3 queries will be scheduled. The middleware can try to retrieve the status from a query and depending on the "Success/ Falied" the middleware can delay / cancel the next one's run (document is there, but I have not done it, so needs to be thought of with care)

I would say try to go for #1 - in that case, every block will store start & end of every block in a single log dataset which will be retrieved before execution of the next block!

Hope this helps!
