我试过通过JDBC连接到teredata DB.我正在使用jar的’terajdbc4.jar’和’tdgssconfig.jar’,但我得到了一个ClassNotFoundException和NoClassDefFoundError,因为找不到某种com.ncr.teradata.jtdgss.TdgssManager.
请帮我找一个解决方案.我提供了我的代码片段,后跟错误日志.
用户名和密码是正确的,因为使用该ID通过UNIX连接到teradata DB.
public class HelloTeradataJDBC {
public static void main(String[] args) throws Exception {
String url="jdbc:teradata://10.10.***.**/DBS_PORT= 1025/DATABASE= ******/TMODE=ANSI,CHARSET=UTF8";
try{
Class.forName("com.ncr.teradata.TeraDriver");
Connection conn=DriverManager.getConnection(url, "*****", "******");
//Connection conn=DriverManager.getConnection(connurl, "javauser1", "password1");
String query="select * from xi.san_emp";
PreparedStatement stmt=conn.prepareStatement(query);
ResultSet rs=stmt.executeQuery();
while(rs.next()) {
String col1=rs.getString(1);
System.out.println("col1="+col1);
}
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}
错误:

最佳答案 这会奏效.驱动程序名称是com.teradata.jdbc.TeraDriver而不是com.ncr.teradata.TeraDriver,我认为这是日期.
Class.forName("com.teradata.jdbc.TeraDriver");
conn = DriverManager.getConnection("jdbc:teradata://"+servername+"/databasename="+this.username+",user="+this.username+",password="+this.password);
