Method set_isolation_level

lib/sqlalchemy/engine/interfaces.py:2461–2493

Given a DBAPI connection, set its isolation level. Note that this is a dialect-level method which is used as part of the implementation of the :class:`_engine.Connection` and :class:`_engine.Engine` isolation level facilities; these APIs should be preferred for

        If the dialect also implements the

        level is guaranteed to be one of the string names within that sequence,
        and the method will not need to anticipate a lookup failure.
