original code, the contents of the parsing Excel are as follows:Xssfworkbook Hssfworkbook = new Xssfworkbook (File.getinputstream ());It can be concluded that the current code only supports format resolution for Excel 2007 and cannot support 2003 format. Therefore, abnormal information is generated.4. SolutionTo resolve multiple formats for Excel 2003 and Excel 2007, use the following code to provide good

Change the encoding of the MySQL program:MySQL modified the code, linux/mac/unix/Universal modified MySQL encoding needs to use the MYSLQ configuration file, the file in/etc/my.cnf,mac user default is not this file, you can go to the MySQL installation director

the remote query, instead of returning the result locally, the filter is executed locally (with a filter)This will certainly be very slow, because the query does not use the index lookup, you need to transfer all the remote data to the local before the filtering, equivalent to full table scan, but also more network transmission time.3. ResolveIn fact, you can resolve performance issues by committing query statements with a WHERE condition to the Oracle server to perform remote queries.However,

rollback from the Binlog innodb transaction. This ensures that the Binlog feedback innodb the exact data of the table, etc., and keeps the slave server in sync with the primary server (without taking the rollback statement). Innodb_flush_log_at_trx_commit (This works well) Complaining that InnoDB is 100 times times slower than MyISAM? Then you probably forgot to adjust the value. The default value of 1 means that every single transaction commit or out-of-transaction instruction requires the log
