更改Mysql列的值

Question

I have two question

at first:

we have Table user with column usergroupid ". I want to find all "2" values in this column and change to "1"

and second question:

How can I do change the value only for id's 100 > end, not do the change for first 100 id's

User id's Column name userid

Answer 1

Assuming userid are sequential and starts from 1, if you want to update usergroupid from 2 to 1 to the greater than 100 id you can try this

UPDATE user
SET usergroupid = 1
WHERE usergroupid = 2
AND userid > 100
