Oliver Lee commented on CALCITE-5662:
-------------------------------------
I've fixed the title of the JIRA ticket.
I have a PR to enable it but I just saw your comment about the SQL standard, I
went to verify and yes, the current behavior follows that.
(PR for reference: https://github.com/apache/calcite/pull/3168)
Let me look into how we can toggle whether to enable it for certain dialects,
I'll comment again when I have the final PR ready

> Currently attempting to run {{SELECT CAST(BOOLEAN as INTEGER)}} will throw a
> {{NumberFormatException}}.
> The BigQuery dialect allows casting {{boolean}} literals to the following:
> {{string}}, {{int64}} , {{tinyint}}, {{smallint}}, {{bigint}}

> Desired behavior:
> {{SELECT CAST(TRUE as INTEGER)}} -> {{1}}
> {{SELECT CAST(TRUE as BIGINT)}} -> {{1}}
> {{SELECT CAST(FALSE as INTEGER)}} -> {{0}}
> {{SELECT CAST(null as INTEGER)}} -> {{null}}
