查了下手册，错误代码2634的相关信息如下：
2634 Existing ERROR table(s) or Incorrect use of
%TVMID in Fast Load operation.
Explanation: This error occurs if the table/error table(s) specified either;
(a) existed before the start of the Fast Load, or
(b) did not indicate that it was involved in this specific Fast Load.
Notes: This error means either that the user has referenced existing tables for the ERRORFILES in a Fast Load that is not restarting, or that incorrect tables were
referenced in a restart of a Fast Load.
Remedy: If this is not a restart of a previous Fast Load, delete the referenced error files. If this is a restart, correct the Begin Loading Statement so that the error files are those specified for the original Fast Load.
我们很明显地可以看出，这个错误的原因是我们在不是restarting的fastload中，ERRORFILES引用了已经存在的表。
解决办法：
在fastload开始之前加入以下语句删除errorfiles所指定的表：
DROP TABLE error_1; /* error table ,internal to fast load utility needed to be defined */
DROP TABLE error_2; /* error table ,internal to fast load utility needed to be defined */
总结：
BEGIN LOADING stu_fl
ERRORFILES error_1, error_2;
1. 在一个不是restarting的fastload中，如果errorfiles指定的表已经存在，就会报2634的错；
2. 如果fastload的过程中不出错，error_1, error_2是不会自动生成的；
3. 我们可以select * from error_1；查看相关的错误信息；
