在SQL Server中使用存儲過程的代碼

先在SQL Server中創建存儲過程如下：
CREATE PROCEDURE InsertOrtho
(@ChildID varchar(10) out,
@date datetime out,
@therapistID varchar(10) out,
@clinicID integer out,
@skeletal varchar(1) out,
@angleClass varchar(1) out,
@deflection varchar(1) out,
@OrthoNotes varchar(200) out)
AS
BEGIN
INSERT INTO tblPatIEntOrtho VALUES
(@ChildID, @date, @TherapistID, @ClinicID, @Skeletal, @angleClass, @deflection, @OrthoNotes)
RETURN
END

這是一個向數據庫插入的存儲過程，所有的參數都是輸出的，在Java裡可以這樣調用這個存儲過程，程序如下：
前面數據庫的連接我就不寫了
public boolean InsertOrtho(Ortho ortho, String childID)
{
boolean success = true;

try
{
CallableStatement stmt = con.prepareCall("{call InsertOrtho(?, ?, ?, ?, ?, ?, ?, ?)}");
stmt.registerOutParameter(1, Java.sql.Types.VARCHAR);
stmt.registerOutParameter(2, Java.sql.Types.TIMESTAMP);
stmt.registerOutParameter(3, Java.sql.Types.VARCHAR);
stmt.registerOutParameter(4, Java.sql.Types.INTEGER);
stmt.registerOutParameter(5, Java.sql.Types.VARCHAR);
stmt.registerOutParameter(6, Java.sql.Types.VARCHAR);
stmt.registerOutParameter(7, Java.sql.Types.VARCHAR);
stmt.registerOutParameter(8, Java.sql.Types.VARCHAR);

stmt.setString(1, childID);
stmt.setObject(2, ortho.GetDate());
stmt.setString(3, ortho.GetTherapistID());
stmt.setInt(4, ortho.GetClinicID());
stmt.setString(5,
