This class is based on the dialect-agnostic :class:`_sql.Insert` construct which may be constructed using the :func:`_sql.insert` function in SQLAlchemy Core. The :class:`_sqlite.Insert` construct includes additional methods :meth:`_sqlite.Insert.on_conflict_do_update`, :meth:`_sqlite.Insert.on_conflict_do_nothing`. r)tables `C:\xampp\htdocs\tradingbinance\backend\.venv\Lib\site-packages\sqlalchemy/dialects/sqlite/dml.pyrr s" %=ceZdZdZdZdZej d dZe dddiZ e e d d d Z e e d dd Z y)ra?SQLite-specific implementation of INSERT. Adds methods for SQLite-specific syntaxes such as ON CONFLICT.

This attribute provides all columns in this row to be referenceable. .. tip:: The :attr:`_sqlite.Insert.excluded` attribute is an instance of :class:`_expression.ColumnCollection`, which provides an interface the same as that of the :attr:`_schema.Table.c` collection described at :ref:`metadata_tables_and_columns`. With this collection, ordinary names are accessible like attributes (e.g. ``stmt.excluded.some_column``), but special names and dictionary method names should be accessed using indexed access, such as ``stmt.excluded["column name"]`` or ``stmt.excluded["values"]``.
