连接Oracle数据库的Hibernate配置文件
连接Oracle数据库的Hibernate配置文件连接Oracle的Hibernate配置文件有两种格式,一种是xml格式的,另一种是Java属性文件格式的。
连接Oracle数据库的Hibernate配置文件
连接Oracle的Hibernate配置文件有两种格式,一种是xml格式的,另一种是Java属性文件格式的。下面分别给出这两种格式配置文件的代码。
1.xml格式的配置文件
下面将给出连接本地Oracle服务器上的db_database02数据库时Hibernate配置文件hibernate.cfg.xml的代码。
例程2-5:光盘\mr\02\sl\05\hibernate.cfg.xml
/P>
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
oracle.jdbc.driver.OracleDriver
jdbc:oracle:thin:@localhost:1521:db_database02
在上面的代码中,“localhost”代表本地Oracle服务器,如果想连接其他服务器可以修改为要连接的Oracle服务器的名称; “db_database02”为要连接的数据库名称;“SYSTEM”为登录用户名;“SYSTEM”表示用户密码; “UserForm.hbm.xml”为持久化类对应的映射文件名称。
2.Java属性文件格式的配置文件
下面将给出连接本地Oracle服务器上的db_database02数据库时Hibernate配置文件hibernate.properties的代码。
例程2-6:光盘\mr\02\sl\06\hibernate.properties
#指定连接数据库使用的SQL方言#
hibernate.dialect=org.hibernate.dialect.MySQLDialect
#指定连接数据库的驱动程序#
hibernate.connection.driver_class=oracle.jdbc.driver.OracleDriver
#指定连接数据库的URL#
hibernate.connection.url=jdbc:oracle:thin:@localhost:1521:db_database02
#指定连接数据库的用户名#
hibernate.connection.username=SYSTEM
#指定连接数据库的密码#
hibernate.connection.password=SYSTEM
#指定在执行程序时,是否在控制台上输出SQL语句#
hibernate.show_sql=true
在上面的代码中,“localhost”代表本地Oracle服务器,如果想连接其他服务器可以修改为要连接的Oracle服务器的名称;“db_database02”为要连接的数据库名称;“SYSTEM”为登录用户名;“SYSTEM”表示用户密码。
说明:在Hibernate包的etc目录下附带了一个用于连接各种关系数据库配置代码的hibernate.properties文件,读者可以根据该文件写出连接其他数据库的配置文件。

How to check which table space a table belongs to in Oracle: 1. Use the "SELECT" statement and specify the table name to find the table space to which the specified table belongs; 2. Use the database management tools provided by Oracle to check the table space to which the table belongs. Tools usually provide a graphical interface, making the operation more intuitive and convenient; 3. In SQL*Plus, you can view the table space to which the table belongs by entering the "DESCRIBEyour_table_name;" command.

Overview of how to use PDO to connect to Oracle database: PDO (PHPDataObjects) is an extension library for operating databases in PHP. It provides a unified API to access multiple types of databases. In this article, we will discuss how to use PDO to connect to an Oracle database and perform some common database operations. Step: Install the Oracle database driver extension. Before using PDO to connect to the Oracle database, we need to install the corresponding Oracle

Steps for Oracle to fetch only one piece of duplicate data: 1. Use the SELECT statement combined with the GROUP BY and HAVING clauses to find duplicate data; 2. Use ROWID to delete duplicate data to ensure that accurate duplicate data records are deleted, or use "ROW_NUMBER" ()" function to delete duplicate data, which will delete all records except the first record in each set of duplicate data; 3. Use the "select count(*) from" statement to return the number of deleted records to ensure the result.

Implementing data import into PHP and Oracle databases In web development, using PHP as a server-side scripting language can conveniently operate the database. As a common relational database management system, Oracle database has powerful data storage and processing capabilities. This article will introduce how to use PHP to import data into an Oracle database and give corresponding code examples. First, we need to ensure that PHP and Oracle database have been installed, and that PHP has been configured to

How to efficiently use connection pooling in PHP and Oracle databases Introduction: When developing PHP applications, using a database is an essential part. When interacting with Oracle databases, the use of connection pools is crucial to improving application performance and efficiency. This article will introduce how to use Oracle database connection pool efficiently in PHP and provide corresponding code examples. 1. The concept and advantages of connection pooling Connection pooling is a technology for managing database connections. It creates a batch of connections in advance and maintains a

The oracle database requires jdk. The reasons are: 1. When using specific software or functions, other software or libraries included in the JDK are required; 2. Java JDK needs to be installed to run Java programs in the Oracle database; 3. JDK provides Develop and compile Java application functions; 4. Meet Oracle's requirements for Java functions to help implement and implement specific functions.

Oracle's steps to determine whether a table exists in a stored procedure: 1. Use the "user_tables`" system table to query the table information under the current user, compare the incoming table name "p_table_name" with the "table_name" field, and if the conditions are met, then "COUNT(*)" will return a value greater than 0; 2. Use the "SET SERVEROUTPUT ON;" statement and the "EXEC`" keyword to execute the stored procedure and pass in the table name to determine whether the table exists.

How to use PHP to extend PDO to connect to Oracle database Introduction: PHP is a very popular server-side programming language, and Oracle is a commonly used relational database management system.
