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

Skills | Connecting to a database Java database connection (JDBC) consists of a set of classes and interfaces written in the Java programming language. JDBC provides tools/database developers with a standard API that enables them to write database applications with a pure Java API. However, each developer's interface is not exactly the same, so the development en

I encountered a problem where I used ojdbc14.jar (which version I don't remember) to insert 0.1 million records in batches. Actually, I only inserted more than 30 thousand records, but I lost others. After I changed to ojdbc6.jar, I encountered a problem where I used ojdbc14.jar (which version I don't remember) to insert 0.1 million records in batches.
