application performance. You can further improve the performance by executing the statement pool multiple times during the application running. However, we should realize that the statement pool is not a panacea for solving performance problems. If each statement is cached and the number of times it is executed in the program is not identified, no performance improvement is possible. In fact, because storing statements in the cache and saving them in the cache results in overhead, caching state

The Blob field in Oracle is special. It has much better performance than the long field and can be used to save binary data such as sample slices.Writing Blob fields is very different from writing other types of fields. Because Blob itself has a cursor, you must use cursor to operate blob. Therefore, before writing Blob, you must obtain the cursor to write data. How can you obtain the Blob cursor?This requires you to insert an empty blob first, which
