1293 - Incorrect table definition; there can be only oneTIMESTAMP column with CURRENT_TIMESTAMP

一个表中出现多个timestamp并设置其中一个为current_timestamp的时候经常会遇到
1293 - Incorrect table definition; there can be only oneTIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATEclause
原因是当你给一个timestamp设置为on updatecurrent_timestamp的时候，其他的timestamp字段需要显式设定default值
但是如果你有两个timestamp字段，但是只把第一个设定为current_timestamp而第二个没有设定默认值，mysql也能成功建表,但是反过来就不行…
N.B:红色的解释是网上的，实际上on updatecurrent_timestamp（在navicat中文版中为“刷新当前时间戳计时”选项）只能设置一个，或者不设置都可以，不能同时设置2个及以上。
