Note that we have to maintain same number of columns while using UNION query. Like we do in MS Excel we can display sum of all columns and the sum of all total subject marks by using UNION. LEAST(social,science,math) as min FROM student_sum idĭisplaying sum of all columns at last row We can list starting from highest mark to lowest mark by using Order By Query.įrom student_sum GROUP BY id ORDER BY Total DESC Displaying highest & lowest mark in all subjects of each student SELECT id,name,GREATEST(social,science,math) as max, Listing all columns along with aggregate functions like sum(), max() using over() with partition → Displaying from Highest to lowest SELECT id,name,class, social, math, science, Note that id is unique value column in our table. Now we will try to display all marks and sum of them for each student by using group by. Query to display percentage value using 2 decimal places.įORMAT((( social + science + math)/(95*3) * 100),2) AS percentageįROM `student_sum` Sum of the row data of each record The above percentage data is having four decimal places, we can format these numbers by using ROUND Sql command. (( social + science + math)/(95*3) * 100) AS percentage SELECT id, name, class,( social + science + math) as Total, SELECT name, (( social + science + math)/(95*3) * 100) AS percentageįROM `student_sum` Displaying Total Mark with Percentageīoth total mark and percentage we can display like this So to get the percentage mark of each student we have to multiply 95 with 3 ( for three subjects ) and then divide that from the total and multiply with 100 here is the query. Let us assume the full mark in each subject is 95. We can add various other sql commands like where clause etc. SELECT sum(social + math + science ) as total So the sum is to be collected in all three columns. Now we will try to get sum of marks of all students in all subjects. SQL file for betweeen query sql_between.Related Tutorial MySQL SUM MySQL Max MySQL Min MySQL AvgĪs you can see the above sum is sum of marks of each student. Selecting records between two date ranges Are there any alternatives to using the "BETWEEN" operator in SQL for achieving similar functionality?.Is the "BETWEEN" operator inclusive or exclusive in SQL?

If yes, provide an example.What is the syntax for using the "BETWEEN" operator in SQL?.How does the "BETWEEN" operator work in SQL?.What is the purpose of the "BETWEEN" operator in SQL?.Here is the sample code in PHP to to get data using between query.Įcho "$row$row$row$row" We can create a comparative statement in a grid view by using SQL IF and between command How many number of students have secured mark between 60 and 75 in each class by using GROUP BY SELECT class, COUNT(id) as no FROM `student` WHERE mark BETWEEN 60 AND 75 GROUP BY class class SELECT * FROM `student`WHERE mark BETWEEN 60 and 75 AND class IN('Four','Seven') idĭisplaying from limited class using NOT IN SELECT * FROM `student`WHERE mark BETWEEN 60 and 75 AND class NOT IN('Four','Seven') id SELECT * FROM `student`WHERE mark BETWEEN 60 and 75 AND class ='Four' id We will restrict the students of class four only By default it is from lowest range to highest range. SELECT * FROM `student`WHERE mark BETWEEN 60 and 75 order by mark descīy using DESC we are getting results from highest to lowest. Using order by we can change the above display and show from highest to lowest. SELECT count(*) FROM student WHERE mark BETWEEN 60 and 75 7 Using NOT SELECT * FROM `student`WHERE mark NOT BETWEEN 50 and 100 How many records are there within this limit ( USE count() )? So the records between 60 and 75 will be displayed ( NOT BETWEEN 75 and 60 ) ![]() Note that we have to first start with lower limit and then upper limit. You can see we have all the records between 60 and 75 ( both inclusive). SELECT * FROM `student`WHERE mark BETWEEN 60 and 75 id So we will get all the records within these limits and note that Say for our mark column upper limit is 75 and lower limit isĦ0. On this table we will apply our BETWEEN command to get all the records ![]() We will apply here BETWEEN command to a numeric field and see how the records are ![]() SQL BETWEEN to get rows within a range with all other commands
