I want to update all records in my database table with a fixed value for pwDays
and an increasing value in pWDate
.
My current statement:
update [POSUSER] set passDays = '60', passChangeDate = '2017-01-01 00:00:00'
But I do not want all users to have to reset their passwords on the same day. So I would like to increment the passChangeDate
by 1 day for every 10 to 20 users, is there a "simplistic" way to do this in a single SQL statement?
(All users must have a new passChangedDate
, but no more than 20 users must have the same date.)
The table has a primary key field that is a integer value. (USERID
)
Note I want to only increase the date after every +/-10% users.
Best Answer
Since you have a primary key
userid
, you can do it with a query like :This query will work the same with any type of primary key (numeric or not) or any set of unique columns. But if there is no way to build a unique identifier of a row, the query won't work and you'll have to make your update another way.
