Java database connection (JDBC) APIs are a series of interfaces that allow Java programmers to access databases. different developers have different interfaces. After using JDBC from Oracle for many years, I have accumulated many skills that allow us to better utilize the system performance and implement more functions. 1. use the Thin

We have already seen that JDBC DriverManager can is used to get relational database connections. But if it comes to actual programming, we want more than just connections.Most of the times we is looking for loose coupling for connectivity so, we can switch databases easily, connection POOling for transaction management and distributed systems support. JDBC DataSource is the preferred approach if you be look

create bridges between Java programs and data sources. The application needs to be written once and can be moved to a variety of drivers to run. Sun provides a driver manager, a database vendor-such as MySQL, Oracle, which provides drivers that meet the requirements of the driver manager and can be identified to work properly. Therefore,

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
