Description

Describe the bug Currently some step queries can cause the generated SQL to fail.

To Reproduce Steps to reproduce the behavior:

  1. Create a new funnel
  2. Add a large SQL query to a step
  3. Attempt to run a query against the funnel cube
  4. See error

Expected behavior CubeJS should wrap any step SQL queries with braces () to prevent issues with the outer query.

Version: v0.15.0

Contributor guide

Research direction
Inspect the funnel query builder in the CubeCore code to identify where step SQL queries are generated and add parentheses wrapping.
