| //! This crate provides: |
| //! |
| //! 1. A SQL parser, [`DFParser`], that translates SQL query text into |
| //! an abstract syntax tree (AST), [`Statement`]. |
| //! |
| //! 2. A SQL query planner [`SqlToRel`] that creates [`LogicalPlan`]s |
| //! from [`Statement`]s. |
| //! |
| //! 3. A SQL [`unparser`] that converts [`Expr`]s and [`LogicalPlan`]s |
| //! into SQL query text. |
| //! |
| //! [`DFParser`]: parser::DFParser |
| //! [`Statement`]: parser::Statement |
| //! [`SqlToRel`]: planner::SqlToRel |
| //! [`LogicalPlan`]: datafusion_expr::logical_plan::LogicalPlan |
| //! [`Expr`]: datafusion_expr::expr::Expr |
