Various types of DDL (CREATE / DROP) catalog manipulation

Variants

CreateExternalTable(Box<CreateExternalTable>)

Creates an external table. Boxed to keep LogicalPlan enum size down — CreateExternalTable is ~312 bytes, dwarfing every other variant in the plan tree and forcing the whole enum to that width.

CreateMemoryTable(CreateMemoryTable)

Creates an in memory table.

CreateView(CreateView)

Creates a new view.

CreateCatalogSchema(CreateCatalogSchema)

Creates a new catalog schema.

CreateCatalog(CreateCatalog)

Creates a new catalog (aka “Database”).

CreateIndex(CreateIndex)

Creates a new index.

DropTable(DropTable)

Drops a table.

DropView(DropView)

Drops a view.

DropCatalogSchema(DropCatalogSchema)

Drops a catalog schema

CreateFunction(Box<CreateFunction>)

Create function statement. Boxed for the same reason as Self::CreateExternalTable (~288 bytes).

DropFunction(DropFunction)

Drop function statement

Implementations

impl DdlStatement

pub fn schema(&self) -> &DFSchemaRef

Get a reference to the logical plan’s schema

pub fn name(&self) -> &str

Return a descriptive string describing the type of this DdlStatement

pub fn inputs(&self) -> Vec<&LogicalPlan>

Return all inputs for this plan

pub fn display(&self) -> impl Display + '_

Return a formatable structure with the a human readable description of this LogicalPlan node per node, not including children.

See crate::LogicalPlan::display for an example
