mssql2000如何利用JDBC连接两个数据库……在线等
我现在有条SQL语句select count(1) from changjie.dbo.Sm_deliver_backup a
where a.itemid=998806
and a.[time] > = 20070616000000 and a.[time] < 20070616240000
and substring(CONVERT (varchar(50),usernumber),0,8) in
(select number from shike.dbo.[sm_分省市号码段] where 省= '福建 ')
我想利用JDBC连接changjie和Shike这两个数据库,JDBC该如何编写。
我现在JDBC是这样的
public ConnectJdbc()//利用构造方法设置数据库驱动程序和连接好数据库
{
try
{
Class.forName(DriverName);
}catch(
ClassNotFoundException e)
{
e.printStackTrace();
System.out.println( "数据库驱动程序加载异常! "+e);
}
try
{
conn=DriverManager.getConnection( "jdbc:microsoft:sqlserver://192.168.2.139:1433;DatabaseName=changjie;User=sa;Password=63586500 ");
}catch(
SQLException e)
{
e.printStackTrace();
System.out.println( "数据库连接程序加载异常! "+e);
}
}
这只能连上changjie数据库,想要同时连上changjie和Shike两个数据库该怎么写这个JDBC?
------解决方案--------------------conn1=DriverManager.getConnection( "jdbc:microsoft:sqlserver://192.168.2.139:1433;DatabaseName=changjie;User=sa;Password=63586500 ");
conn2=DriverManager.getConnection( "jdbc:microsoft:sqlserver://192.168.2.139:1433;DatabaseName=changjie;User=sa;Password=63586500 ");
conn1和conn2 用的时候分开用;我没用过,你试以下吧
------解决方案--------------------conn=DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs;User=sa;Password=sa ");
------解决方案--------------------还有别的答案没有啊?
---------------------------------
答案是:没有!
