new 0460d8a502 Adjust SQL "cannot plan" error message. (#12903)
0460d8a502 is described below
commit 0460d8a502fa5a1c5e06ef542fc9edf3aeb65e77
Author: Gian Merlino <[email protected]>
AuthorDate: Mon Aug 29 06:03:00 2022 -0700
Adjust SQL "cannot plan" error message. (#12903)
Two changes:
1) Restore the text of the SQL query. It was removed in #12897, but
then it was later pointed out that the text is helpful for end
users querying Druid through tools that do not show the SQL queries
that they are making.
2) Adjust wording slightly, from "Cannot build plan for query" to
"Query not supported". This will be clearer to most users. Generally
the reason we get these errors is due to unsupported SQL constructs.
