andygrove opened a new issue, #2219:
URL: https://github.com/apache/arrow-datafusion/issues/2219

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   As a user of the DataFusion library for SQL parsing and logical query planning, I would like to be able to produce a valid logical plan from a SQL query containing an `EXISTS` subquery instead of failing with `Unsupported ast node Exists`.
   
   Example query: `SELECT * FROM a WHERE EXISTS (SELECT * FROM b WHERE a.id = b.id)`
   
   **Describe the solution you'd like**
   The SQL should parse without error and produce a valid logical plan.
   
   **Describe alternatives you've considered**
   None
   
   **Additional context**
   This is a subset of issue https://github.com/apache/arrow-datafusion/issues/123 which aims to add full support for `EXISTS`, including a physical plan.
