Don't close the connection for a user account with expired password. |
| CLIENT_COMPRESS |
Compression protocol supported. |
| CLIENT_CONNECT_ATTRS |
Client supports connection attributes. |
| CLIENT_CONNECT_WITH_DB |
Database (schema) name can be specified on connect in Handshake Response Packet. |
| CLIENT_DEPRECATE_EOF |
Client no longer needs EOF_Packet and will use OK_Packet instead. |
| CLIENT_FOUND_ROWS |
Send found rows instead of affected rows in EOF_Packet. |
| CLIENT_IGNORE_SIGPIPE |
Client only flag. Not used. |
| CLIENT_IGNORE_SPACE |
Ignore spaces before '('. |
| CLIENT_INTERACTIVE |
This is an interactive client. Use System_variables::net_wait_timeout versus System_variables::net_interactive_timeout. |
| CLIENT_LOCAL_FILES |
Can use LOAD DATA LOCAL. |
| CLIENT_LONG_FLAG |
Get all column flags. Longer flags in Protocol::ColumnDefinition320. |
| CLIENT_LONG_PASSWORD |
Use the improved version of Old Password Authentication. Assumed to be set since 4.1.1. |
| CLIENT_MULTI_RESULTS |
Enable/disable multi-results. |

Special handling of ODBC behavior. |
| CLIENT_PLUGIN_AUTH |
Client supports plugin authentication. |
| CLIENT_PLUGIN_AUTH_LENENC_CLIENT_DATA |
Enable authentication response packet to be larger than 255 bytes. When the ability to change default plugin require that the initial password field in the Protocol::HandshakeResponse41 paclet can be of arbitrary size. However, the 4.1 client-server protocol limits the length of the auth-data-field sent from client to server to 255 bytes. The solution is to change the type of the field to a true length encoded string and indicate the protocol change with this client capability flag. |

| CLIENT_PROTOCOL_41 | |
| CLIENT_PS_MULTI_RESULTS |
Multi-results and OUT parameters in PS-protocol. |

| SERVER_STATUS_AUTOCOMMIT |

| SERVER_STATUS_CURSOR_EXISTS |
The server was able to fulfill the clients request and opened a read-only non-scrollable cursor for a query. This flag comes in reply to COM_STMT_EXECUTE and COM_STMT_FETCH commands. Used by Binary Protocol Resultset to signal that COM_STMT_FETCH must be used to fetch the row-data. |
| SERVER_STATUS_DB_DROPPED |
A database was dropped. |
| SERVER_STATUS_IN_TRANS |
Is raised when a multi-statement transaction has been started, either explicitly, by means of BEGIN or COMMIT AND CHAIN, or implicitly, by the first transactional statement, when autocommit=off. |
| SERVER_STATUS_IN_TRANS_READONLY |
Set at the same time as SERVER_STATUS_IN_TRANS if the started multi-statement transaction is a read-only transaction. Cleared when the transaction commits or aborts. Since this flag is sent to clients in OK and EOF packets, the flag indicates the transaction status at the end of command execution. |
