This article mainly describes how to greatly improve the performance of Oracle JDBC programs by using the connection and statement pool features. We generally use pool technologies, such as connection pool and statement pool, to significantly improve the performance of database-intensive applications, because this can achieve Object reuse, you do not need to spend time and resources to recreate objects. If
the empty blob type object is empty_blob (). Then, you can use the SELECT command to query the previously inserted records and lock them. Then, you can change the empty object to the lob object to be inserted.Third, the modification methods are different.Update... Set... Command. For a field of the lob type, only select... The for update command is used to query and lock records before modification. There are also two ways to modify: one is to modify (overwrite) the original data and execute se
