Method register_temp_table

crates/integrations/datafusion/src/sql_context.rs:197–216

Registers a temporary in-memory table or view. The `name` parameter accepts flexible table references, similar to DataFusion: - `"my_table"` — uses the current catalog and current database - `"database.my_table"` — uses the current catalog with the specified database - `"catalog.database.my_table"` — fully qualified The table exists only for the lifetime of this SQLContext instance.
