`errors` -- Package exceptions ============================== .. module:: psycopg.errors .. index:: single: Error; Class This module exposes objects to represent and examine database errors. .. currentmodule:: psycopg .. index:: single: Exceptions; DB-API .. _dbapi-exceptions: DB-API exceptions ----------------- In compliance with the DB-API, all the exceptions raised by Psycopg derive from the following classes: .. parsed-literal:: `!Exception` \|__ `Warning` \|__ `Error` \|__ `InterfaceError` \|__ `DatabaseError` \|__ `DataError` \|__ `OperationalError` \|__ `IntegrityError` \|__ `InternalError` \|__ `ProgrammingError` \|__ `NotSupportedError` These classes are exposed both by this module and the root `psycopg` module. .. autoexception:: Error() .. autoattribute:: diag .. autoattribute:: sqlstate The code of the error, if received from the server. This attribute is also available as class attribute on the :ref:`sqlstate-exceptions` classes. .. autoattribute:: pgconn It has been closed and will be in `~psycopg.pq.ConnStatus.BAD` state; however it might be useful to verify precisely what went wrong, for instance checking the `~psycopg.pq.PGconn.needs_password` and `~psycopg.pq.PGconn.used_password` attributes. Attempting to operate this connection will raise an :exc:`OperationalError`. .. versionadded:: 3.1 .. autoattribute:: pgresult .. versionadded:: 3.1 .. autoexception:: Warning() .. autoexception:: InterfaceError() .. autoexception:: DatabaseError() .. autoexception:: DataError() .. autoexception:: OperationalError() .. autoexception:: IntegrityError() .. autoexception:: InternalError() .. autoexception:: ProgrammingError() .. autoexception:: NotSupportedError() Other Psycopg errors ^^^^^^^^^^^^^^^^^^^^ .. currentmodule:: psycopg.errors In addition to the standard DB-API errors, Psycopg defines a few more specific ones. .. autoexception:: ConnectionTimeout() .. autoexception:: PipelineAborted() .. index:: single: Exceptions; PostgreSQL Error diagnostics ----------------- .. autoclass:: Diagnostic() The object is available as the `~psycopg.Error`.\ `~psycopg.Error.diag` attribute and is passed to the callback functions registered with `~psycopg.Connection.add_notice_handler()`. All the information available from the :pq:`PQresultErrorField()` function are exposed as attributes by the object. For instance the `!severity` attribute returns the `!PG_DIAG_SEVERITY` code. Please refer to the PostgreSQL documentation for the meaning of all the attributes. The attributes available are: .. attribute:: column_name constraint_name context datatype_name internal_position internal_query message_detail message_hint message_primary schema_name severity severity_nonlocalized source_file source_function source_line sqlstate statement_position table_name A string with the error field if available; `!None` if not available. The attribute value is available only for errors sent by the server: not all the fields are available for all the errors and for all the server versions. .. _sqlstate-exceptions: SQLSTATE exceptions ------------------- Errors coming from a database server (as opposite as ones generated client-side, such as connection failed) usually have a 5-letters error code called SQLSTATE (available in the `~Diagnostic.sqlstate` attribute of the error's `~psycopg.Error.diag` attribute). Psycopg exposes a different class for each SQLSTATE value, allowing to write idiomatic error handling code according to specific conditions happening in the database: .. code-block:: python try: cur.execute("LOCK TABLE mytable IN ACCESS EXCLUSIVE MODE NOWAIT") except psycopg.errors.LockNotAvailable: locked = True The exception names are generated from the PostgreSQL source code and includes classes for every error defined by PostgreSQL in versions between 9.6 and 15. Every class in the module is named after what referred as "condition name" `in the documentation`__, converted to CamelCase: e.g. the error 22012, ``division_by_zero`` is exposed by this module as the class `!DivisionByZero`. There is a handful of... exceptions to this rule, required for disambiguate name clashes: please refer to the :ref:`table below ` for all the classes defined. .. __: https://www.postgresql.org/docs/current/errcodes-appendix.html#ERRCODES-TABLE Every exception class is a subclass of one of the :ref:`standard DB-API exception `, thus exposing the `~psycopg.Error` interface. .. versionchanged:: 3.1.4 Added exceptions introduced in PostgreSQL 15. .. autofunction:: lookup Example: if you have code using constant names or sql codes you can use them to look up the exception class. .. code-block:: python try: cur.execute("LOCK TABLE mytable IN ACCESS EXCLUSIVE MODE NOWAIT") except psycopg.errors.lookup("UNDEFINED_TABLE"): missing = True except psycopg.errors.lookup("55P03"): locked = True .. _exceptions-list: List of known exceptions ^^^^^^^^^^^^^^^^^^^^^^^^ The following are all the SQLSTATE-related error classed defined by this module, together with the base DBAPI exception they derive from. .. autogenerated: start ========= ================================================== ==================== SQLSTATE Exception Base exception ========= ================================================== ==================== **Class 02** -
