Module datafusion_physical_expr_common::utils

Functions

• limited_convert_logical_expr_to_physical_expr_with_dfschema
  Converts datafusion_expr::Expr into corresponding Arc<dyn PhysicalExpr>. If conversion is not supported yet, returns Error.
• reverse_order_bys
  Reverses the ORDER BY expression, which is useful during equivalent window expression construction. For instance, ‘ORDER BY a ASC, NULLS LAST’ turns into ‘ORDER BY a DESC, NULLS FIRST’.
• scatter
