You can use a subquery like this :
SELECT * FROM Category WHERE Sid = 3 AND Bid = 0
AND Name NOT IN (SELECT Name FROM Category WHERE Sid = 3 AND Bid = 8)

I need to find the sum of the names and then choose the bigger.
I need to show that the max name is John smith because it's 4 times.
I guess you need the most repeated name. You may try below query -
SELECT writer, COUNT(*)
FROM YOUR_TABLE
GROUP BY writer
ORDER BY COUNT(writer) DESC
LIMIT 1;

student(sID,sNAME,sCLASS);
result(sID,subMARKS);
Actually, in MS-ACCESS, i am trying to this with equi join but getting wrong result. i'm writting my query like
SELECT stud.sID
, stud.sNAME
, stud.sCLASS
, result.sID
FROM student
, result
WHERE(SELECT MAX(subMARKS) FROM result)
It should display Ali record only because he is having maximum marks. but i am getting this kind of output as shown in picture below.
sID sNAME sCLASS
1 Ali BSC
2 Ahmad FSC
3 Asgar ICS
4 Akram BSC
SELECT T1.SID, T1.sname FROM student T1
LEFT JOIN resultT2 ON t1.sid=t2.sid
WHERE t2.submarks = (SELECT Max(submarks) FROM result);

I have a table called 'list' that is like this:
system item1 exception
------------------------
A John 1
A Sarah 0
A Tim 1
A Blake 0
B Nikki 1
B Rick 0
C Jimbo 1
I am trying to build a query and I'm so terrible at it and I'm stuck. I want to return all rows unconditionally UNLESS system = 'A'. If system = 'A' then only return the rows where exception is true.
Thanks for your time.
What about this?
SELECT * FROM table WHERE system != 'A' OR exception = 1
SQL FIDDLE DEMO
select *
from list
where (system = 'A' and exception = 1)
or system <> 'A'
You can group conditions in the WHERE clause by enclosing each block in ()

I'm working on an IPN for PayPal, and I need to know how to select a certain amount of rows where sold='false'
The following should work:
SELECT * FROM your_table WHERE sold='false' LIMIT 10
select * from table where sold='false' limit 10
OR
select * from table where sold='false' limit M,N
this query fetches data starts from Mth row to N number of records
.
select top 10 * from table where sold='false'

I have this table, answers:

I want to create a view in phpMyAdmin that can display the question number, the total number of answers to that question and the number of right answers to that question.
I would like it to look like:
question
total answers
right answers
1
3
2
2
4
3
Could anyone help me to make this view? How do I create the query? I have tried something about count(*) where rightAnswer=1, but I cannot get it to count BOTH the total number of answers and the number of answers of each question.
try something like this:
select question,count(*),sum(rightAnswer)
from TABLE
group by question
order by question
select question, count(*) as total_answers, sum(rightAnswer) as right_answers
from your_table
group by question
order by question
Using ms sql syntax:
SELECT Question, totalAnswers.Total, rightAnswers.correct
FROM answers AS a
INNER JOIN (
SELECT Question, COUNT(rightanswer) AS correct
FROM answers
WHERE rightanswer = 1
GROUP BY Question
) rightAnswers
ON a.Question = rightAnswers.QUestion
INNER JOIN (
SELECT Question, COUNT(rightanswer) AS total
FROM answers
GROUP BY Question
) totalAnswers
ON a.Question = rightAnswers.QUestion
