Snowflake Scripting - SQL Cursors

Snowflake scripting in SQL seems to be in preview and I have decided to have a play with it. Given how new it is there is limited documentation so I am using a combination of what I can find on the Snowflake site and the odd blog that has been written about it. There appear to be a few quirks, at least when compared to Oracle PL/SQL (though that has been round for years). How many of these are intentional and how many are things to be ironed out I don't know. You can see the procedure I have created it: 

  • Accepts an id as a parameter 
  • Creates a result set selecting from a table, using the parameter as a filter
  • Loads the results set into a cursor. 
  • Loops through the cursor loading the id in the cursor into variable
  • Calls procedure passing in the variable as the parameter. 
Then as a proof of concept I tried the Snowflake feature of allowing declaration of variables within the main start and end block.

Keboola Flows

Really finding Keboola was the thing that kickstarted this project otherwise I would be trying to build custom code on a python cloud server and building everything from scratch.  In Keboola you build you data sources and destinations using connection details which is fairly simple and something I will likely cover in another post, same goes for transformations etc. Here though I am going to discuss Flows, this is where you bring everything together. On my free account there are some limitations.  My easiest flow is very basic:  Pull parkrun results e-mail from Gmail to Google Sheets (actually done by Zap not Keboola).  Keboola will, as often as I like, in this case once a week, pull the data from the sheet into its storage.  It will then transfer this to the target database. Currently I have this setup to be MySQL database but I can and might expand that to the Snowflake instance within Keboola.  I then, outside of Keboola, connect to the MySQL database f...
