[−][src]Enum datafusion::logicalplan::LogicalPlan
The LogicalPlan represents different types of relations (such as Projection, Selection, etc) and can be created by the SQL query planner and the DataFrame API.
Variants
Projection
A Projection (essentially a SELECT with an expression list)
Fields of Projection
Selection
A Selection (essentially a WHERE clause with a predicate expression)
Fields of Selection
Aggregate
Represents a list of aggregate expressions with optional grouping expressions
Fields of Aggregate
Sort
Represents a list of sort expressions to be applied to a relation
Fields of Sort
TableScan
A table scan against a table that has been registered on a context
Fields of TableScan
EmptyRelation
An empty relation with an empty schema
Fields of EmptyRelation
Limit
Represents the maximum number of records to return
Fields of Limit
expr: Expr
The expression
input: Arc<LogicalPlan>
The logical plan
schema: Arc<Schema>
The schema description
CreateExternalTable
Represents a create external table expression.
Fields of CreateExternalTable
