关于恢复数据库SQL2000出现的问题！！高手帮忙解决下 谢谢
我用的是JSP+JAVABEAN实现恢复这个功能，但有时候能够恢复   有时候却提示错误：][SQL   Server]未能找到存储过程   'kill51 '

高手帮忙解决下   谢谢

JAVABEAN里代码为：
public   void   cut(String   datebasename)throws   Exception
                {
                      Connection   con=DriverManager.getConnection( "jdbc:odbc:sun1 ", "sa ", " ");
                      Statement   stmt=con.createStatement();
                      ResultSet   rs=null;
                      rs=stmt.executeQuery( "select   spid   from   sysprocesses   where   dbid=db_id( ' "+datebasename+ " ') ");
                      while(rs.next())
                          {
                          stmt.execute( "kill "   +   rs.getInt( "spid "));
                          }
              }
    public   void   rdata(String   datebasename,String   bakfile)throws   Exception
          {
                Connection   con=DriverManager.getConnection( "jdbc:odbc:sun1 ", "sa ", " ");
                Statement   stmt=con.createStatement();
                stmt.executeUpdate( "restore   database   "+datebasename+ "   from   disk= ' "+bakfile+ " ' ");
              }

[解决办法]
Statement stmt=con.createStatement();
Statement stmt2=con.createStatement();
ResultSet rs=null;
rs=stmt.executeQuery( "select spid from sysprocesses where dbid=db_id( ' "+datebasename+ " ') ");
while(rs.next())
{
stmt2.execute( "kill " + rs.getInt( "spid "));
}
