- Tip For a detailed explanation of DuckDB internals, see the Design and Implementation of DuckDB Internals ("DiDi") library entry. On this page is a brief description of the internals of the DuckDB engine. Parser The parser converts a query
...string into the following tokens: SQLStatement QueryNode TableRef ParsedExpression The parser is not aware of the catalog or any other aspect of the database. It will not throw er...able source. This can be a reference to a base table, but it can also be a join, a table-producing function or a subquery. QueryNode The QueryNode represents either (1) a SELECT statement, or (2) a set operation (i.e., UNION , INTERSECT or DIFFERENCE ). S...ypes are resolved Aggregate/window functions are extracted The following conversions happen: SQLStatement → BoundStatement QueryNode → BoundQueryNode TableRef → BoundStatement ParsedExpression → Expression Logical Planner The logical planner creates Logic... - https://man.mtool.work/duckdb/2.0/internals/overview.html
