How do I connect to a SQL Server 2008 database in Java with JDBC?
我有一个需要连接到MS SQL数据库的程序。但它没有连接。
这是我的代码：
DB db = new DB();
db.dbConnect("jdbc:jtds:sqlserver://WEBAPRTestSPXAMRProdSQL.Traxtech.com/WEBAPRTest_SPXAMRProd","ralph.caballes","*****"); //<-- i think the error is here
class DB
{
public void dbConnect(String db_connect_string, String db_userid, String db_password){
Connection con = null;
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection(db_connect_string, db_userid, db_password);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
请帮忙。
