Hello,

I want to know how to create custom Expectation to compare 2 query results? Is there a tutorial I can watch applicable for GECore v1.1.1?

Thanks!

Unfortunately, there is not a tutorial for this specific custom expectation you are wishing to implement, however this section in our docs outlines the process of inheriting the class of an existing expectation. From there you may use SQL to write the logic to compare 2 query results.
