Boost C++ Libraries

incomplete_message

An incomplete message was received from the server (indicates a deserialization error or packet mismatch).

protocol_value_error

An unexpected value was found in a server-received message (indicates a deserialization error or packet mismatch).

server_unsupported

The server does not support the minimum required capabilities to establish the connection.

extra_bytes

Unexpected extra bytes at the end of a message were received (indicates a deserialization error or packet mismatch).

sequence_number_mismatch

Mismatched sequence numbers (usually caused by a packet mismatch).

unknown_auth_plugin

The user employs an authentication plugin not known to this library.

auth_plugin_requires_ssl

The authentication plugin requires the connection to use SSL.

wrong_num_params

The number of parameters passed to the prepared statement does not match the number of actual parameters.

server_doesnt_support_ssl

The connection mandates SSL, but the server doesn't accept SSL connections.

metadata_check_failed

The static interface detected a mismatch between your C++ type definitions and what the server returned in the query.

num_resultsets_mismatch

The static interface detected a mismatch between the number of row types passed to static_results or static_execution_state and the number of resultsets returned by your query.

row_type_mismatch

The StaticRow type passed to read_some_rows does not correspond to the resultset type being read.

static_row_parsing_error

The static interface encountered an error when parsing a field into a C++ data structure.

timeout

(EXPERIMENTAL) An operation controlled by Boost.MySQL timed out.

cancelled

(EXPERIMENTAL) An operation controlled by Boost.MySQL was cancelled.

pool_not_running

(EXPERIMENTAL) Getting a connection from a connection_pool failed because the pool is not running. Ensure that you're calling connection_pool::async_run.

invalid_encoding

(EXPERIMENTAL) An invalid byte sequence was found while trying to decode a string.

unformattable_value

(EXPERIMENTAL) A formatting operation could not format one of its arguments.

format_string_invalid_syntax

(EXPERIMENTAL) A format string containing invalid syntax was provided to a SQL formatting function.

format_string_invalid_encoding

(EXPERIMENTAL) A format string with an invalid byte sequence was provided to a SQL formatting function.

format_string_manual_auto_mix

(EXPERIMENTAL) A format string mixes manual (e.g. {0}) and automatic (e.g. {}) indexing.

format_string_invalid_specifier

(EXPERIMENTAL) The supplied format specifier (e.g. {:i}) is not supported by the type being formatted.

format_arg_not_found

(EXPERIMENTAL) A format argument referenced by a format string was not found. Check the number of format arguments passed and their names.

unknown_character_set

(EXPERIMENTAL) The character set used by the connection is not known by the client. Use set_character_set or async_set_character_set before invoking operations that require a known charset.

max_buffer_size_exceeded

(EXPERIMENTAL) An operation attempted to read or write a packet larger than the maximum buffer size. Try increasing any_connection_params::max_buffer_size.
