Domo uses MySQL 5.6+

@VERSION for the exact version number.

 

This version of MySQL predates the implementation of Windowed functions.

 

You can recreate it using user defined variables.

Without performance tuning in MySQL, you'll probably get faster performance using MagicETL if you start using larger datasets.

If you create a Redshift transform instead of SQL, you can use LAG.  I was shown how to create a Redshift dataflow to get active clients by month using start and end date on the client record.
