問(wèn)題：根據(jù)唯一字段編碼修改其它字段，修改部分?jǐn)?shù)據(jù)，數(shù)量在上萬(wàn)條數(shù)據(jù)，數(shù)據(jù)大，一開(kāi)始就卡死了！笨辦法，一條一條修改不知可年可月啊。其他方法個(gè)人原因?qū)嵲谑菬o(wú)能為力。如下：

百度結(jié)果：百度了一下，很多解決方案，有的寫的很粗糙，完全不理解，也許自己水平問(wèn)題。有的是自己真的看不懂，個(gè)人水平跟不上。
解決方案：最后的解決辦法，還是老辦法，就是新建一張臨時(shí)表（表B：a_2017 ），把所修改的唯一字段編碼和修改后的數(shù)據(jù)放在B表。sql大體如下（原表A：ka02_new ，唯一字段aka060 ，修改的字段分別為aka065 和aka166 ）：
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);
