Java连接Sybase ASE数据库的一个简单例子
演示在用java连接Sybase ASE数据库。用了一个简单的java程序作试验。
第一步：获得jdbc for sybase驱动程序
下载JDBC驱动：http://www.sybase.com/detail?id=1009726
也可到CSDN下载：http://download.csdn.net/source/2697077
有jConnect6.05和jConnect5.5两种。jConnect6.05中包含jconn3.jar包，jConnect5.5中包含jconn2.jar包。建议最新的Sybase驱动jconn3.jar。不过我的这个例子很简单，两者都可以用。
下载：jconn3.jar ，下载：jconn2.jar
第二步：设置环境变量CLASSPATH
将下载下来的jconn2.jar或jconn3.jar放到目录D:\sybase\Shared\lib下。将环境变量CLASSPATH设置为：D:\sybase\Shared\lib\jconn2.jar
set CLASSPATH=.;d:\sybase\shared\lib\jconn2.jar; (注意：第一个“.”，这个代表当前目录。)
第三步：编写一段简单的java程序。
下面的这段程序用jconn2.jar连接Sybase ASE15.0.3数据库并提取master数据库中的用户表的ID和name两列信息。
Sybase ASE数据库的ip地址为：192.168.0.168，端口：5000。登录sa的密码为：sybase
执行：select id,name,crdate from dbo.sysobjects where type='U' 这条语句返回当前数据库（这在url中指定！）中的用户表的id和name列。
import java.sql.*;
import java.util.*;public class Conn2ASE {
public static void main(String[] args) {
try {
Class.forName("com.sybase.jdbc2.jdbc.SybDriver").newInstance();
String url = "jdbc:sybase:Tds:192.168.0.168:5000/master";// 数据库名
Properties sysProps = System.getProperties();
sysProps.put("user", "sa"); // 设置数据库访问用户名
sysProps.put("password", "sybase"); // 密码
Connection conn = DriverManager.getConnection(url, sysProps);
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
String sql = "select id,name,crdate from dbo.sysobjects where type='U'"; // 表
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
System.out.println("oject_id:"+rs.getString(1)+",oject_name:"+rs.getString(2)); // 取得第二列的值
}
rs.close();
stmt.close();
conn.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
将上面这段代码保存到：d:\sybase\shared\demo\Conn2ASE.java
第四步：编译java源文件为class文件
Java编译器javac.exe的版本为：1.5.0_15
javac.exe Conn2ASE.java
C:\Documents and Settings\Administrator>cd /d d:\sybase\shared\demo
D:\sybase\Shared\demo>set CLASSPATH=.;d:\sybase\shared\lib\jconn2.jar;
D:\sybase\Shared\demo>D:\sybase\WorkSpace\JDK1.5.0_15\bin\javac.exe Conn2ASE.jav
a
D:\sybase\Shared\demo>dir
驱动器 D 中的卷没有标签。
卷的序列号是 24C3-2A76
D:\sybase\Shared\demo 的目录
2010-09-15 17:08 <DIR> .
2010-09-15 17:08 <DIR> ..
2010-09-15 17:08 1,683 Conn2ASE.class
2010-09-15 17:02 1,107 Conn2ASE.java
2 个文件 2,790 字节
2 个目录 18,468,270,080 可用字节
第五步：执行java程序连接Sybase ASE数据库，并显示查询结果
java程序的版本也是：1.5.0_15
java Conn2ASE
D:\sybase\Shared\demo>java Conn2ASE
