1、把jar包添加到库：DmJdbcDriver18.jar（在安装目录/drivers/jdbc下）因为我使用的jdk版本是11，所以用DmJdbcDriver18，它支持1.8及以上版本的jdk。
创建表并进行增删改查操作
package DM;
import java.sql.*;

public
class ConnectDM8 {
static String jdbcString =
"dm.jdbc.driver.DmDriver";
static String urlString =
"jdbc:dm://localhost:5236";//
定义连接用户名
static String userName =
"SYSDBA";//
定义连接用户口令
static String password
=
"SYSDBA";//
定义连接对象
static Connection conn =
null;
public
static void findAll() {
try {
Class.forName(jdbcString);
conn = DriverManager.getConnection(urlString, userName, password);
Statement stmt = conn.createStatement();
ResultSet resultSet = stmt.executeQuery("select * from DMHR.JOB");
while(resultSet.next())
{
System.out.print("JOB_ID:"+resultSet.getInt(1));
System.out.print(" JOB_TITLE:"+resultSet.getString(2));
System.out.print(" MIN_SALARY:"+resultSet.getInt(3));
System.out.println(" MAX_SALARY:"+resultSet.getInt(4));
}
resultSet.close();
stmt.close();
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public
static void createTble()
{
try {
Class.forName(jdbcString);
conn = DriverManager.getConnection(urlString, userName, password);
Statement stmt = conn.createStatement();
//
int i = stmt.executeUpdate("create table users(uid int,uname varchar(10));");
boolean flag = stmt.execute("create table users(uid int,uname varchar(10));");
if(flag)
System.out.println("建表成功");
else
System.out.println("建表失败");
System.out.println(flag);
stmt.close();
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public
static void insert()
{
try {
Class.forName(jdbcString);
conn = DriverManager.getConnection(urlString, userName, password);
Statement stmt = conn.createStatement();
int i = stmt.executeUpdate("insert into users values(1,‘messi‘) ");
if (i!=0)
System.out.println("插入成功");
else
System.out.println("插入失败");
stmt.close();
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public
static void delete()
{
try {
Class.forName(jdbcString);
conn = DriverManager.getConnection(urlString, userName, password);
Statement stmt = conn.createStatement();
int i = stmt.executeUpdate("delete users where uid=1");
if (i!=0)
System.out.println("删除成功");
else
System.out.println("删除失败");
stmt.close();
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public
static void main(String[] args) {
// createTble();
//

//
delete();
findAll();
}
}
1、检查gcc 包
[root@localhost ~]# rpm -aq|grep gcc
没有的话就安装： yum install gcc -y
2、安装unixODBC-2.3.9
1)解压：tar -xvf unixODBC-2.3.9.tar.gz
cd unixODBC-2.3.0
2）./configure
3）make &&. make install
3、编辑配置文件odbc.ini、odbcinst.ini
vi /usr/local/etc/odbc.ini
[dm8]
Description = DM ODBC DSN
Driver = DM8 ODBC DRIVER
SERVER = localhost
UID = SYSDBA
PWD = SYSDBA
TCP_PORT = 5236
vi /usr/local/etc/odbcinst.ini
[DM8 ODBC DRIVER]
Description = ODBC DRIVER FOR DM8
Driver = /home/dmdba/dmdbms/bin/libdodbc.so
4、切换到dmdba用户登录
su - dmdba
isql dm8
