我是用的是idea自带的database
加入数据的行数

比如,添加国家的时候,数据很多,uuid如何自动生成呢
利用excel,在函数输入栏粘贴下面的函数表达式:
=CONCATENATE(IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)),IF(RANDBETWEEN(1,2)=1,CHAR(RANDBETWEEN(0,9)+48),CHAR(RANDBETWEEN(0,5)+97)))

此时出现了一条uuid
生成多条的时候,需要用到

鼠标放到箭头位置,会出现+号,往下拖,就可以出现多条

我们将此列数据粘贴到数据库

就可以在数据库直接生成uuid啦,
输好数据后右击点submit,才可以生效哦。

本文介绍了如何使用IDEA内置数据库工具批量生成UUID。通过在Excel中利用复杂的函数表达式生成随机字符串,形如UUID,然后复制到数据库中。只需将公式拖动即可创建多条UUID,最后提交到数据库完成数据录入。
