大家好，在这里向你们请教一个问题。
有一个A表，里面有140W的数据，现在对部分 ‘过期’ 数据要做备份，我将它分成两部分导出，一部分是过期的（old），一部分是要继续留下的(new)
因为考虑到方便，在清表后，将"一部分是要继续留下的(new)"数据重新Load进表里。
首先:
<code>
export to td_fm_unites_20110531_olddata.txt of del select * from tbl where time<'20110531';
export to td_fm_unites_20110531_newdata.txt of del select * from tbl where time>'20110531';
</code>
Export完成后，
<code>
[db2inst1@itcc db2databak]$ wc -l td_fm_unites_20110531_newdata.txt
939817 td_fm_unites_20110531_newdata.txt
[db2inst1@itcc db2databak]$ wc -l td_fm_unites_20110531_olddata.txt
457457 td_fm_unites_20110531_olddata.txt
</code>
然后， 我创建一个空文件 del.del
<code>
load from del.del of del
insert into tbl;
<code>
将 tbl表里面的数据清空。
此时,将td_fm_unites_20110531_newdata的数据Load到表里
load from td_fm_unites_20110531_newdata.txt of del
insert into tbl;
但是Load后，发现数据少了很多。
db2 => load from td_fm_unites_20110531_newdata.txt of del
db2 (cont.) => insert into td_fm_unites;
load from td_fm_unites_20110531_newdata.txt of del insert into td_fm_unites
