oracle调用java程序连sqlserver2005
1、在oracle的sys-sysdba下登陆
写一个java source程序链接sqlserver2005:
create or replace and compile java source named test as
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class excutesql1
{
public static String entry(String str1,String str2) {
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
// 加载jdbc驱动
String a = "0";
String dbURL = "jdbc:sqlserver://localhost:1433;DatabaseName=wb"; // 链接数据库服务和驱动sample
String userName = "sa"; // 用户名
String userPwd = "giap"; // 密码
Connection dbConn;
try {
a = "1";
Class.forName(driverName);
dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
String sql = "insert into ry_jbxx (RYBH,XM) values ('" + str1
+ "','" + str2 + "')";
PreparedStatement pstmt = dbConn.prepareStatement(sql);
pstmt.addBatch();
pstmt.executeBatch();
a = "2";
} catch (Exception e) {
e.printStackTrace();
a = "error";
}
return a;
}
}
(注:java程序可以用loadjava的方式load到oracle中,也可以利用plsql写java source)
2、在oracle的sys-sysdba下登陆
用loadjava将sqlserver2005驱动load到oracle,在dos下执行:
loadjava -u sys/giap@zhxtdb -r -v sqljdbc.jar
测试链接是否成功:
写一个函数:
create or replace function insert2(a varchar2, b varchar2) return varchar2 as
language java name 'excutesql1.entry(java.lang.String,java.lang.String) return java.long.String';
测试链接!~
(注:一定要在sysdba下执行)
Sqlserver2005测试数据库:
CREATE TABLE [dbo].[msg](
[tel] [varchar](50) NOT NULL,
[msg] [varchar](50) NULL
)
3、测试成功后在普通用户(giapzhxt)下建表:
create table MSG
(
TEL VARCHAR2(20),
MSG VARCHAR2(200)
)
tablespace GIAPDATA
pctfree 10
initrans 1
maxtrans 255
storage
(
initial 64K
minextents 1
maxextents unlimited
);
4、在oracle的sys-sysdba下登陆
New一个存储过程
create or replace procedure insertsqlserver2005(a varchar2, b varchar2) as
language java name 'excutesql1.entry(java.lang.String,java.lang.String)';
在sys-sysdba下登陆new一个普通用户(giapzhxt)下表的触发器来执行存储过程:
create or replace trigger tri_zhxt_msg
after insert on giapzhxt.msg
for each row
begin
insertsqlserver2005(:new.tel,:new.msg);
end tri_zhxt_msg;
实现:oracle中的表通过java程序向sqlserver2005表中写数据!~

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Building a Hadoop Distributed File System (HDFS) on a CentOS system requires multiple steps. This article provides a brief configuration guide. 1. Prepare to install JDK in the early stage: Install JavaDevelopmentKit (JDK) on all nodes, and the version must be compatible with Hadoop. The installation package can be downloaded from the Oracle official website. Environment variable configuration: Edit /etc/profile file, set Java and Hadoop environment variables, so that the system can find the installation path of JDK and Hadoop. 2. Security configuration: SSH password-free login to generate SSH key: Use the ssh-keygen command on each node
