This PR add the
MERGE INTOstatement used by Trino/Athena/Snowflake/IcebergReference:
https://trino.io/docs/current/sql/merge.html
https://docs.snowflake.com/en/sql-reference/sql/merge
https://docs.aws.amazon.com/athena/latest/ug/merge-into-statement.html
Note:
I also added the "keyword_check" bash script to the test command, so that we check it during development and not just during CI
I think T-SQL and Oracle also support this statement. On a quick glance, Oracle should be covered, T-SQL has some extra commands.
[Update]: I just realized that Postgres also supports this 😲 It also is almost fully covered! https://www.postgresql.org/docs/current/sql-merge.html
