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!~
