i have the following search and replace sql:

update jos_lmusers
set group_id = "GROUP_ID"
where users_id = "USER_ID"

I'm able to use this to update one single field for which I have entered a user id. but i would like to update multiple fields, how do I add more user ids to this code. would it be something like this??

update jos_lmusers
set group_id = "group_id"
where users_id = "user_id-1","user_id-2"

your input would be most appreciated!!

You can search on multiple id's using an IN statement.

Alternatively you would have to use OR statements.

users_id = "user1" OR users_id = "users2"
update jos_lmusers
set group_id = "GROUP_ID"
where users_id IN ("user_id-1","user_id-2")

Open in new window

You want the "IN" operator:

update jos_lmusers
set group_id = "group_id"
where users_id IN ("user_id-1","user_id-2")

oh, and you probably want to use single quotes there instead of double quotes

For MySQL, you may be able to use ANY keyword as well:

WHERE users_id = ANY("user_id-1","user_id-2")

But IN works on other platforms as well.

I thought so to petiex, but I thought maybe I just don't use MySQL enough. :)
Figured it was allowed since ` is the column identifier instead of ".  Still think it is a good idea to use ' as again it is common on other platforms of SQL like IN versus ANY.

Anyway, good luck.

OK you kind of ask about updating multiple fields and also adding more users...

Add fields into the update by seperating with a comma, and use the IN clasue in the where statement, and encapsulate your literams with a single comma :

update jos_lmusers
set group_id = 'group_id', other_field = 'Other'
where users_id IN ('user_id-1','user_id-2')

 and if you want to make it conditional, then use a case statement

update jos_lmusers
set group_id = 'group_id', other_field = case when users_id = 'user_id-2' then 'Other_2' else 'Other_1' end
where users_id IN ('user_id-1','user_id-2')

Hope that covers it all off for you...

@ost87 - interesting - why did you give it to petiex when mwvisa had also (previously) posted the same code ? Just interested that's all.

:( Wasn't even a simultaneous post, I typed in more text and posted 2 MINs ahead.

Just glad you got the answer you were looking for.  Hopefully you saw that all three of us think you should go with single quotes (') for string literals in MySQL.
