Fields

aggregates_table: TableRef

Table ref that represents output of aggregate expressions.

aggregates: Vec<Expression>

Aggregate expressions.

group_table: Option<TableRef>

Table ref representing output of the group by expressions.

Will be None if this aggregate does not have an associated GROUP BY.

group_exprs: Vec<Expression>

Expressions to group on.

grouping_sets: Option<Vec<BTreeSet<usize>>>

Grouping set referencing group exprs.

grouping_functions_table: Option<TableRef>

Table reference for getting the GROUPING value for a group.

This is Some if there’s an explicit GROUPING function call in the query. Internally, the hash aggregate produces a group id based on null bitmaps, and that id is stored with the group. This let’s us disambiguate NULL values from NULLs in the column vs NULLs produced by the null bitmap.

Follows postgres semantics. See: https://www.postgresql.org/docs/current/functions-aggregate.html#FUNCTIONS-GROUPING-TABLE

grouping_functions: Vec<GroupingFunction>

Grouping function calls.

Empty if grouping_set_table is None.
