示例Java程序调用Teradata存储过程

我想从Java程序调用Teradata存储过程，任何人都可以使用示例java程序吗？示例Java程序调用Teradata存储过程

由于受到一些限制，我无法在Teradata内部创建一些UDF函数，因此我在Teradata中开发了这些函数作为存储过程。

现在，我需要使用Java程序调用这些过程。

朋友，这是我的java程序，

public static String executeme(String x,String y) throws SQLException, ClassNotFoundException 
{ 
    System.out.println(" Message: 2 "); 
    String connectionString = "jdbc:teradata://192.168.0.0/xyz,tmode=ANSI,charset=UTF8,DBS_PORT=1025,DATABASE=xyz"; 
    String user = "xyz"; 
    String passwd = "xxx"; 
    System.out.println(" Message: 3 after url " +x); 
    String sCall = "{CALL "+x+"(?,?)}"; 
    System.out.println(" Message: after call str " +sCall); 
    String result = null; 

    try 
    { 
     Class.forName("com.teradata.jdbc.TeraDriver"); 

     Connection con = DriverManager.getConnection(connectionString, user, passwd); 
     System.out.println(" Message: after con "+con ); 
     CallableStatement cStmt = con.prepareCall(sCall); 
     cStmt.setString(1, y); 
     cStmt.registerOutParameter(2, Types.VARCHAR);   
     result = cStmt.getString(2); 

     return result; 


    }  
    catch(ClassNotFoundException e) 
    { 
     System.out.println(" Message: " + e); 
     return e.toString();  
    } 



} 
public static void main(String[] args) throws SQLException, ClassNotFoundException { 
    // TODO Auto-generated method stub 

    String outs=null; 
    System.out.println(" Message: 1 "); 
    outs = testing.executeme("sample_name", "ABCD"); 
    System.out.println(outs); 
}

但是，运行该程序时，我得到的错误：

Message: 1 
Message: 2 
Message: 3 after url ment_f_swithin 
Message: after con [email protected]

我试着使用所有3种模式ANSI，TERA ，BTET。而我依然得到相同的错误，请指点我请

Connection conn1; 

<... connect conn1 ...> 

conn1.createStatement().execute("call proc_test()");

就不是这一行：

String connectionString = "jdbc:teradata://192.168.0.0/xyz,tmode=ANSI,charset=UTF8,DBS_PORT=1025,DATABASE=xyz";

我变成

String connectionString = "jdbc:teradata://192.168.0.0/tmode=ANSI,charset=UTF8";
