Decimal”,结果的系数由值的系数位数构成; 科学记数法用于绝对值小于“1e-6”的值和最低有效位的位值大于1的值,否则使用定点记数法。< /><br />无论精度如何,正负无穷大,正负零和nans 分别被格式化为inf、-inf、0、-0和nan`。 G' 一般格式。 与'g' 相同,但如果数字太大则切换到 'E'。
https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_date-format 里面有1个%f,但是是6位的,如果毫秒只需要3位,再套一层substring,效果如下: 上图也顺便给了另1个小技巧:默认情况下now()和current_timestamp()函数,只精确到秒,如果需要到毫秒,传入3或6这样的精度值即可。
