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!~
