table_name: str | None = None

__post_init__() → None

classmethod column(name: str, *, table: str | None = None) → ExpressionDependency

Create a column dependency optionally qualified with a table.

classmethod table(name: str) → ExpressionDependency

Create a dependency representing an entire table.
