You might be wondering how we can add transactions into our code if we do not deal directly with the JDBC classes. It is then for the application developer to decide how to proceed in the event of connection errors and failures. From a programming point of view, it is the same as if your thread called DriverManager. It is critical that the syntax be specified correctly. Further, for load-balanced connections, the statement will be executed against one connection in the internal pool, rather than validating each underlying physical connection.

The fix corrects the return value from getMaxBytesPerChar. Working connections were not being removed from the blacklist.

The data and how it is stored for ResultSet rows are now behind an interface which enables us in some cases to allocate less memory per row, in that for "streaming" result sets, we re-use the packet used to read rows, since only one row at a time is ever active.

People often omit facts because they think they know the cause of a problem and assume that some details do not matter. BugBugBug Fixed configuration property jdbcCompliantTruncation was not being used for reads of result set values.

The backend storage of myxql provided using Connection.

Use the StringUtils method instead. Added enableStreamingResults to Statement for connection pool implementations that check Statement. When using versions of the JDBC driver earlier than 3.

This is of limited use, as it may 3.0.71 that a packet was just sent, while a packet from the server has not been received for several hours. This needs to be created first using the following procedure.

Failover happens when the driver determines that the connection has failed checked before every queryand falls back myslq the first host when it determines that the host has become available again after queriesBeforeRetryMaster queries have been issued. Column names don't match metadata in cases where server doesn't connecror original column names column functions thus breaking compatibility with applications that expect 1-to-1 mappings between findColumn and rsmd.

Calendars and timezones are now lazily instantiated when required.

ResultSet returned by Statement. The optimal size for the connection pool depends on anticipated load and average database transaction time. Failover attempts between two read-write masters did not properly set this.

If the URL property autoReconnect is connectkr Major changes are isolated to new functionality exposed in MySQL This is a lighter weight solution. To get the configuration started, we need to create the DAO. After the driver has been registered with the DriverManageryou can obtain a Connection instance that is connected to a particular database by calling DriverManager.
