JDBC series tutorial (5) --- prepare statements
Preparedstatement
This overview is taken from jdbctm database access from javatm: a tutorial and annotated reference. Javasoft is currently preparing this book. This is a tutorial and an important reference manual for JDBC, which will be published by Addison-Wesley in the spring of 1997 as part of the Java series.

JDBC programming-transaction programming (4)Transaction Concept
In my opinion, the concept of a transaction refers to a set of SQL sequences. This sequence is a unit of execution, either all or all, in this way, you can control the concurrency of the database.Because databases can be operated by multiple users at the same time, if multiple users operate on one data at the same time, data inconsistency may occur. Therefore, transactions are necessary a

Introduction to JDBCJDBC (Java Data Base Connectivity,java database connection) is a Java API for executing SQL statements, which is one of the 13 specifications of Java. You can provide unified access to a variety of relational databases, consisting of a set of classes and interfaces written in the Java language. JDBC provides a benchmark to build more advanced tools and interfaces that enable database developers to write database applications, while
The MyEclipse reports is designed to share the JDBC driver configuration for the database tools used. MyEclipse JDBC This special data source allows reporting tools to access these drivers. This tutorial describes how to set up a myeclipse JDBC data source. You will learn to:
Creating and editing data sources
Manually Synchronizing data sources
Same point:Both are Java's database operations middleware.Both objects that operate directly on the database are not thread-safe and need to be shut down in a timely manner.Both can make explicit transactions on the database's update operations.different points :Different SQL languages used: JDBC uses a relational database-based standard SQL language, Hibernate uses the HQL (Hibernate query Language) languageDifferent objects are manipulated:
Label:Data persistencePersistence (Persistence): Saves data to an off-the-shelf storage device for later use. In most cases, especially for enterprise applications, data persistence means that the data in-memory is saved to the hard disk to be "cured", and the implementation of the persistence process is mostly done through a variety of relational databases. The primary application of persistence is to store in-memory data in a relational database and, of course, in disk files and XML data files
Although many ORM frameworks have emerged, many friends may still be using JDBC. Just like me, apart from learning these excellent frameworks such as Hibernate and Spring, JDBC is always used at work. This article briefly introduces how to use beanutils and dbutils of JakartaCommons to simplify JDBC database operations,
