- 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 errors if tables do not exis...t, and will not resolve any types of columns yet. It only transforms a query string into a set of tokens as specified. ParsedExpression The ParsedExpression represents an expression within a SQL statement. This can be e.g., a reference to a column, an additi...on operator or a constant value. The type of the ParsedExpression indicates what it represents, e.g., a comparison is represented as a ComparisonExpression .
