问题:根据唯一字段编码修改其它字段,修改部分数据,数量在上万条数据,数据大,一开始就卡死了!笨办法,一条一条修改不知可年可月啊。其他方法个人原因实在是无能为力。如下:
sql;">
update ka02_new set aka065=1,aka166=1 where aka060='X-P02CA-A010-A001-2V';
update ka02_new set aka065=1,aka166=1 where aka060='X-P02CA-A010-A001-2W';

百度结果:百度了一下,很多解决方案,有的写的很粗糙,完全不理解,也许自己水平问题。有的是自己真的看不懂,个人水平跟不上。
解决方案:最后的解决办法,还是老办法,就是新建一张临时表(表B:a_2017 ),把所修改的唯一字段编码和修改后的数据放在B表。sql大体如下(原表A:ka02_new ,唯一字段aka060 ,修改的字段分别为aka065 和aka166 ):
sql;">
update ka02_new b
set b.aka065 =
(SELECT a.aka065 FROM a_2017 a WHERE a.aka060 = b.aka060),b.aka166 =
(SELECT a.aka166 FROM a_2017 a WHERE a.aka060 = b.aka060)
WHERE b.aka060 in (SELECT a.aka060 FROM a_2017 a);
