The open-source projects SQLQuack builds on.
SQLQuack’s tokenizer and parser started from code derived from Polyglot, by Tobias (@tobilg). Its DuckDB result-type rules are ported from Polyglot’s engine type rules. Thank you, Tobias.
Thanks also to SQLGlot, by Toby Mao. Polyglot is inspired by SQLGlot, and SQLQuack uses the Snowflake SQL of SQLGlot’s test suite as case inputs, with the expected answers recorded from Snowflake itself.
