mysql selecting data from a table - mysql

I have an Users Table with a staff column and a remove column.
I don't want to show Users that have the remove column with the value of 1
SELECT *
FROM Users
WHERE
Users.staff = 1
AND Users.remove != 1
I don't get an error but my code doesn't work.
this is the schema
CREATE TABLE `Users` (
`userId` int(11) unsigned NOT NULL AUTO_INCREMENT,
`fullName` varchar(50) DEFAULT NULL,
`firstName` varchar(25) NOT NULL DEFAULT '',
`lastName` varchar(25) NOT NULL DEFAULT '',

`city` varchar(25) DEFAULT NULL,
`state` char(2) DEFAULT NULL,

) ENGINE=InnoDB AUTO_INCREMENT=20 DEFAULT CHARSET=latin1;

both work for me Boss.
create table users
( staff int not null,
remove int not null
);
insert users (staff,remove) values (1,0);
insert users (staff,remove) values (1,1);
insert users (staff,remove) values (2,0);
insert users (staff,remove) values (2,1);
SELECT *
FROM Users
WHERE
Users.staff = 1
AND Users.remove != 1
SELECT *
FROM Users
WHERE
Users.staff = 1
AND Users.remove <> 1
Edit due to nullability:
SELECT * FROM Users
WHERE staff=1
and remove <> 1 or remove is null
SELECT * FROM Users
WHERE staff=1
and remove is not null

MySQL find a row when the sum of points become bigger than number

I have such sql query
SELECT *,(p.datetime-u.createtime)/86400 as result
FROM tbl_user_points p
Inner join tbl_users u ON u.id=p.user_id
GROUP BY p.user_id
HAVING SUM(p.points) > 100
order by SUM(p.points)
i need to find the datetime( the row in table tbl_user_points), when each users reached.
For more information Here the schemata of table

tbl_user_points
id | user_id|action|description|points| datetime

2257 2 2 Second visit 15 1383354553
2258 2 3 Winner 25 1383360211
tbl_user simple,for example
id=1,createtime=1313000000
id=2,createtime=1313000001
for HAVING SUM(p.points) > 15
output should be
user_id datetime
1 1383354853
2 1383354553
Use CASE syntax. Check this link:
http://dev.mysql.com/doc/refman/5.0/en/case.html.
You can achieve it by using statements like this:
Select X, case when y>100 then desired_row when y<100 then desired_row end as 'desired_row' from your_table where column=your_condition order by 1
Here you're conditioning the select clause by as many cases or conditions you requiere.

Mysql query failed after adding category table

MySQL IN Statement Hang

What I'm attempting to accomplish is return a SELECT statement of ALL duplicates in a table within given filters.
I'm attempting to run the following query but every time I run it my server locks up and it never completes the query. I have no idea what is causing this and some help would be greatly appreciated on either how to fix this or to accomplish my goal in another manner.

Have you tried joining rather than using a subquery?
SELECT rf.*
FROM red_flags rf
inner join red_flags rf2
on (rf2.customer_number = rf.customer_number)
group by rf2.customer_number
having count(rf2.customer_number) >1
I figured it out, I had a poorly formed date filter that was causing it to break when querying with an IN for some reason.
leads.date >= now() - INTERVAL 30 DAY
