I am pretty new to SQL and need some help with a query. I am trying the find the MAX TradeCodeID using the following query. It is not returning the data I need. It is pretty much returning t.
select distinct
t.useremployeeid,
max(t.usertradeID),
t.Projectfullname,
t.userfirstname + ' '+ t.userlastname as GreatestPM
from
(select distinct
users.UserTradeId, UserEmployeeID, UserFirstName, UserLastName,
ProjectFullName, ProjectManager,
max(ScheduleDate) as LastDate
from
schedules
left outer join
users on ScheduleUserID = UserID
left outer join
Phases on SchedulePhaseID = PhaseID
left outer join
Projects on phases.ProjectID = projects.ProjectID
left outer join
UserTrades on UserTrades.UserTradeID = Users.UserTradeID
where
users.useractive = 1
and users.useremployeeid <> 0
and users.usertradeid between 21 and 24
and projectfullname is not null
group by
users.UserTradeid, UserEmployeeID, UserFirstName, UserLastName,
ProjectFullName, ProjectManager
having
max(scheduledate) > getdate() ) t
group by
t.projectfullname, t.userfirstname,t.userlastname, UserEmployeeID
order by
t.projectfullname
From the following data set:
useremployeeid UserTradeID Projectfullname GreatestPM

In my DB there are three tables. I am trying to figure out how to List the school name, class name and teacher's name. Sort the records by class name within school name. I have a query but it is not working. How can I list the school name, class name and teacher's name and sort record by class name within school name?
SELECT c.class_name FROM class c INNER JOIN teacher t WHERE t.teacher_id = c.teacher_id INNER JOIN school s WHERE t.school_id = s.school_id;

You can use the join to get what you want. This will give the all schools with the teachers and there classes.
SELECT DISTINCT
sc.SCHOOL_NAME,
teach.FIRST_NAME,
teach.LAST_NAME ,
cs.CLASS_NAME
FROM
school sc JOIN teacher teach
ON sc.SCHOOL_ID = teach.SCHOOL_ID
JOIN class cs ON cs.TEACHER_ID = teach.TEACHER_ID
ORDER BY
sc.SCHOOL_NAME,cs.CLASS_NAME
SELECT t.FIRST_NAME +' '+t.LAST_NAME, s.SCHOOL_NAME, c.class_name
FROM class c
INNER JOIN teacher t
ON t.teacher_id = c.teacher_id
INNER JOIN school s
ON t.school_id = s.school_id
ORDER BY s.SCHOOL_NAME,c.CLASS_NAME
Please help me come up with a solution for the situation being explained below:
ID name address age hobby GPA
---------------------------------------------------------
101 James 100 Garfield St 21 reading 3.13
101 James 100 Garfield St 21 writing 2.63
101 James 100 Garfield St 21 running 3.81
109 Tom 19 Lily Ave 19 dating 3.54
109 Tom 20 Lily Ave 19 climbing 2.76
109 Tom 21 Lily Ave 19 watching 3.91
I want to copy the set of rows with the same ID (eg. 101) and assign each set a State abbreviation(s) by running a single sql query. For instance: adding states CA, NJ, and DE to rows with an ID of 101, the result set is expected to look like this:
ID name address age hobby GPA state
-----------------------------------------------------------------------
101 James 100 Garfield St 21 reading 3.13 CA
101 James 100 Garfield St 21 writing 2.63 CA
101 James 100 Garfield St 21 running 3.81 CA
101 James 100 Garfield St 21 reading 3.13 NJ
101 James 100 Garfield St 21 writing 2.63 NJ
101 James 100 Garfield St 21 running 3.81 NJ
101 James 100 Garfield St 21 reading 3.13 DE
101 James 100 Garfield St 21 writing 2.63 DE
101 James 100 Garfield St 21 running 3.81 DE
Please keep in mind that everything else remains the same way as they were before the addition of the state abbreviations. Also assume I have more than three states to add and integrate to the query, say, I have all 50 states. Thank you for your time and effort in advance!
This should produce that result set:
select x.*, y.st
from tbl x
join
(select 'CA' as st union all
select 'NJ' union all
select 'DE') y
where x.id = 101
Create a new table with IDs and States
ID ST
101 CA
101 NJ
101 DE
109 ..
then join that on your table
SELECT t.*, s.st
FROM tbl t
JOIN states s ON t.id = s.id
I am trying to return the country, golfer name, golfer age, and average drive for the golfers with the highest average drive from each country.
However I am getting a result set with duplicates of the same country. What am I doing wrong? here is my code:
select distinct country, name, age, avgdrive
from pga.golfers S1
inner join
(select max(avgdrive) as MaxDrive
from pga.golfers
group by country) S2
on S1.avgdrive = s2.MaxDrive
order by avgdrive;
These are some of the results I've been getting back, I should only be getting 15 rows, but instead I'm getting 20:
COUN NAME AGE AVGDRIVE
---- ------------------------------ ---------- ----------

T&T Stephen Ames 41 285.8

You are missing a join condition:
select s1.country, s1.name, s1.age, s1.avgdrive
from pga.golfers S1 inner join
(select country, max(avgdrive) as MaxDrive
from pga.golfers
group by country
) S2
on S1.avgdrive = s2.MaxDrive and s1.country = s2.country
order by s1.avgdrive;
Your problem is that some people in one country have the same average as the best in another country.
DISTINCT eliminated duplicate rows, not values in some fields.
To get a list of countries with ages, names, and max drives, you would need to group the whole select by country.
I have a SQL Server table with the following fields and sample data:
ID Name Address Age
23052-PF Peter Timbuktu 25
23052-D1 Jane Paris 22
23052-D2 David London 24
23050-PF Sam Beijing 22
23051-PF Nancy NYC 26
23051-D1 Carson Cali 22
23056-PF Grace LA 28
23056-D1 Smith Boston 23
23056-D2 Mark Adelaide 26
23056-D3 Hose Mexico 25
23056-D4 Mandy Victoria 24
Each ID with -PF is unique in the table.
Each ID with the -Dx is related to the same ID with the -PF.
Each ID with -PF may have 0 or more IDs with -Dx.
The maximum number of -Dx rows for a given -PF is 9.
i.e. an ID 11111-PF can have 11111-D1, 11111-D2, 11111-D3 up to 11111-D9.
Output expected for above sample data:
ID ID (without suffix) PF_Name PF_Address PF_Age D_Name D_Address D_Age
23052-PF 23052 Peter Timbuktu 25 Jane Paris 22
23052-PF 23052 Peter Timbuktu 25 David London 24
23050-PF 23050 Sam Beijing 22 NULL NULL NULL
23051-PF 23051 Nancy NYC 26 Carson Cali 22
23056-PF 23056 Grace LA 28 Smith Boston 23
23056-PF 23056 Grace LA 28 Mark Adelaide 26
23056-PF 23056 Grace LA 28 Hose Mexico 25
23056-PF 23056 Grace LA 28 Mandy Victoria 24
I need to be able to join the -PF and -Dx as above.
If a -PF has 0 Dx rows, then D_Name, D_Address and D_Age columns in the output should return NULL.
If a -PF has one or more Dx rows, then PF_Name, PF_Address and PF_Age should repeat for each row in the output and D_Name, D_Address and D_Age should contain the values from each related Dx row.
Need to use MSSQL.
Query should not use views or create additional tables.
Thanks for all your help!

I have database table that I am after some SQL for (Which is defeating me so far!)
Imagine there are 192 Athletic Clubs who all take part in 12 Track Meets per season.
So that is 2304 individual performances per season (for example in the 100Metres)
I would like to find the top 48 (unique) individual performances from the table, these 48 athletes are then going to take part in the end of season World Championships.
So imagine the 2 fastest times are both set by "John Smith", but he can only be entered once in the world champs. So i would then look for the next fastest time not set by "John Smith"... so on and so until I have 48 unique athletes..
hope that makes sense.
thanks in advance if anyone can help
PS
I did have a nice screen shot created that would explain it much better. but as a newish user i cannot post images.
I'll try a copy and paste version instead...
