URL: https://github.com/apache/datafusion-sqlparser-rs/pull/1580
This PR adds support for the `TABLESAMPLE` option in the following dialects:
- Standard SQL:
https://jakewheat.github.io/sql-overview/sql-2016-foundation-grammar.html#sample-clause
- Snowflake: https://docs.snowflake.com/en/sql-reference/constructs/sample
- Hive:
https://cwiki.apache.org/confluence/display/hive/languagemanual+sampling
Collateral work includes expanding the use of a constructor function to
create `Table` structs in unit tests to avoid modifying many files when adding
default options to the `Table` struct.
