Functions

add_offset_to_expr

Adds the offset value to Column indices inside expr. This function is generally used during the update of the right table schema in join operations.

add_offset_to_physical_sort_exprs

create_lex_ordering

Creates a vector of LexOrdering from a vector of logical expression

create_ordering

Converts logical sort expressions to physical sort expressions.

create_physical_sort_expr

Create a physical sort expression from a logical expression

create_physical_sort_exprs

Create vector of physical sort expression from a vector of logical expression

physical_exprs_bag_equal

Checks whether the given physical expression slices are equal in the sense of bags (multi-sets), disregarding their orderings.

physical_exprs_contains

This function is similar to the contains method of Vec. It finds whether expr is among physical_exprs.

physical_exprs_equal

Checks whether the given physical expression slices are equal.
