oracle调用java程序连sqlserver2005

1、在oraclesys-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loadoracle中,也可以利用plsqljava source

 

 

 

2oraclesys-sysdba下登陆

loadjavasqlserver2005驱动loadoracle,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
  );

4oraclesys-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)';

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!~

What steps are required to configure CentOS in HDFS What steps are required to configure CentOS in HDFS Apr 14, 2025 pm 06:42 PM

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.
