Please help me out with the following issue. want to convert row data into the columns based on value of "PeriodNum" column max column will up to period8... there are multiple teachers in the table...below is just sample of 2 teachers.
Sample of data:

I brought the data into a table in SQL Server and was able to pivot to the results you were looking for.
SELECT ID
, TeacherName
,[1] as Period1
,[2] as Period2
,[3] as Period3
,[4] as Period4
,[5] as Period5
,[6] as Period6
,[7] as Period7
,[8] as Period8
FROM
(SELECT ID, TeacherName, peridonum, course_name
FROM teacher) src
PIVOT
(MAX(course_name) FOR peridonum in ([1],[2],[3],[4],[5],[6],[7],[8])
) pvt

Imagine the following table:
result_id student subject grade
1 Anne A 63
2 Anne B 63
3 Bob A 89
4 Bob B 51
5 Carla A 70
6 Carla B 70
7 Carla C 68
8 Dylan B 75
9 Dylan C 54
I would like to return the entries where a student got the exact same grade for subject A and B. So the ideal output would be:
result_id student subject grade
1 Anne A 63
2 Anne B 63
5 Carla A 70
6 Carla B 70
Can this even be achieved with queries? Struggling to find information about it.
A bit complicated but I hope easy to read.
select * from the_table
where student in
(
with t as
(
select student, count(*) cnt, min(grade) mig, max(grade) mag
from the_table
where subject in ('A', 'B') group by student
)
select student from t where mig = mag and cnt = 2
)
and subject in ('A', 'B')
order by student, subject;
result_id
student
subject
grade
1
Anne
A
63
2
Anne
B
63
5
Carla
A
70
6
Carla

This is a simplified version of the tables but I have a table called NAME with 2 columns, names (strings) and classes (strings)

NOTE: All names and classes actually have a numerical ID associated with them, used actual names for illustration.
I want to pair up unique people taking the same class, with the output table looking something like this.
name1
name2
class
Joe

Mat 12
Joe
James
Mat 12
Hector

Mat 12

Worth noting is that the output table should have unique pairs and a person shouldn't be paired with themselves (so don't want outcome like this)
name1
name2
class
Joe
Hector
Mat 12
Hector
Joe
Mat 12
Joe
Joe

I've tried something along the lines of
SELECT NAME.names as name1, NAME.names as name2, NAME.classes as c1, COUNT(*) as pa
FROM NAME
JOIN NAME
ON name1.c1 = name2.c1
GROUP BY name1, name2
ORDER BY c1
But doesn't work.
You may achieve this using a join and comparison based on the index/name
Query #1
SELECT
n1.name as name1,
n2.name as name2,
n1.classes
FROM
NAME n1
INNER JOIN
NAME n2 ON n1.classes=n2.classes AND n1.index < n2.index;

I want to Student Table 1 ---> ID,Name,Surname and Student Table 2 --> School Number,Class Number and ClassBranch joın.But joın is not successful.Class Branch A and B removed and D,F is adding.
First table ID,Name,Surname (3 columns) and Second table School Number,Class Number,Class Branch join.
Where conditions:
Removed column --> 4 - A AND 5 - B
Adding column --> 4- D AND 5- F
How can I write query?
Now that you've completely changed the original tables, this should be a simple JOIN.
SELECT t2.id, t1.name, t1.surname, t2.SchoolNumber, t2.ClassNumber, t2.ClassBranch
FROM Student1 AS t1
JOIN Student2 AS t2 ON t1.name = t2.name AND t1.surname = t2.surname
DEMO
To get those results?
1) The complicated way. By joining them.
SELECT
s2.ID,
s1.Name, s1.Surname,
s2."School Number", s2."Class Number", s2.ClassBranch
FROM Student1 AS s1
JOIN Student2 AS s2 ON (s2.Name = s1.Name AND s2.Surname = s1.Surname)
WHERE s1."Class Number" IN (4, 5);
2) The simple way, select only from the 2nd table
SELECT *
FROM Student2
WHERE "Class Number" IN (4, 5);

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

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!
