Getting the first & Second highest number record from a table
How to get the second highest mark of a class? We will use two sql commands limit and order by along with the select command to get the second highest record in a table. We will use our student table where each student mark is stored in a field. We will try to get the name and other details of a student who secured second highest mark.
Why second highest why not the first highest or the highest mark? That is because it is easy to get highest by using SQL Max command and using limit and order by also we can get the highest mark. After reading this tutorial you can generate that query or see the end of this tutorial to get the highest mark query.
By using order by command we can display the records in the order by marks. By adding the command DESC we can get the records starting from highest to lowest records. So we will get first record of the highest mark and then the second highest mark. We know we can restrict the number of display by using limit command so we will use this limit command to get one record starting from first. So this will return us the second record after the first record. That is if we add the limit command and start from 1 and ask to return 1 record then we will get the second highest mark student. ( not the first or the highest mark ).
Here is the sql command to get the second highest mark of class six students.
SELECT * FROM `student` WHERE class='Six' ORDER BY mark DESC LIMIT 1,1
Output is here
id
name
class
mark
12
Recky
Six
94
Limit command will pick up one record staring after the first record so we will get the second highest. If we want to get the first record or the highest mark student then we have to start from 0 record and display one. Like this
SELECT * FROM `student` where class='Six' ORDER BY mark desc LIMIT 0,1
id
name
class
mark
33
Kenn Rein
Six
96
You can see the only difference between above two SQL commands is the use of starting record mark in limit command. In first case it is 1 and in second case it is set to 0
Displaying top 3 records only
As you can see by using order by and limit command we can display recordes in different orders, now we will try to display the top three records from the top or first three highest marks. Here is the query.
SELECT * FROM `student` WHERE class='Six' ORDER BY mark DESC LIMIT 0,3
Output of this query is here.
id
name
class
mark
33
Kenn Rein
Six
96
12
Recky
Six
94
11
Ronald
Six
89
This way we can display any record, it can be fifth or 12th record from top. If we change the order by command to start in ascending order by changing the DESC to ASC ( or removing it , by default it is ASC ) we can get the lowest to highest and get the records from lowest ( last ) mark.
SELECT * FROM `student` where class = 'Six' ORDER BY mark ASC LIMIT 0,1
Try to find out the second lowest mark of class six now
Here it is
id
name
class
mark
17
Tumyu
Six
54
PHP Code
You can use the same PHP code used for SELECT query by replacing SQL only.
select sal, count, rownum from (select sal , count(sal) count from salary group by sal order by sal desc) where rownum in (1,2,3)

Hi, I need a sql query:- My Requirement is as follows:-
I am working on a project which will take input from the user, & based on the inputs it will give the records.
For Eg:- I need to generate 5 sets of 20 questions . Each set of questions will contain 5 Java Ques, 8 DataBase, 5 .Net, 2 Subjective Questions. So, i am able to get the data from table all the 100 ques(5 X 20). Now before sending it to the user , i need to order the data .
The conditions are as follows:-
First 20 questions will belong to set 1, next 20 questions will belong to set2 and so on .....
So, i need to shuffle the data so that every 20 questions from top will contain 5 Java Ques, 8 DataBase, 5 .Net, 2 Subjective Questions. And the questions should be in arranged in random order. i.e. if the 1st ques is from JAVA , then 2nd ques should not be from JAVA, it should be from other subject. So, two subjects should not be together.

You can sue start date and end date by using date between query , then add AND to it and give maximum price and minimum price.
SELECT * FROM dt_tb WHERE dt BETWEEN '2014-4-2' AND '2014-4-18' and price BETWEEN max_price and min_price
