client_errc

MySQL client-defined error codes.

Synopsis

Defined in header <boost/mysql/client_errc.hpp>

enum class client_errc
    : int;

Values

Name	Description
`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.
`pool_not_running`	Getting a connection from a connection_pool was cancelled before the pool was run. Ensure that you're calling connection_pool::async_run.
`pool_cancelled`	Getting a connection from a connection_pool failed because the pool was cancelled.
`no_connection_available`	Getting a connection from a connection_pool was cancelled before a connection was available.
`invalid_encoding`	An invalid byte sequence was found while trying to decode a string.
`unformattable_value`	A formatting operation could not format one of its arguments.
`format_string_invalid_syntax`	A format string containing invalid syntax was provided to a SQL formatting function.
`format_string_invalid_encoding`	A format string with an invalid byte sequence was provided to a SQL formatting function.
`format_string_manual_auto_mix`	A format string mixes manual (e.g. {0}) and automatic (e.g. {}) indexing.
`format_string_invalid_specifier`	The supplied format specifier (e.g. {:i}) is not supported by the type being formatted.
`format_arg_not_found`	A format argument referenced by a format string was not found. Check the number of format arguments passed and their names.
`unknown_character_set`	The character set used by the connection is not known by the client. Use `any_connection::set_character_set` or `any_connection::async_set_character_set` before invoking operations that require a known charset.
`max_buffer_size_exceeded`	An operation attempted to read or write a packet larger than the maximum buffer size. Try increasing `any_connection_params::max_buffer_size`.

Description

These errors are produced by the client itself, rather than the server.
