Minimum value in a numeric field can be collected by applying MIN sql command.
We will try MIN sql command and how to use it in our tables. But the best way to use MIN command is to apply it in a numeric
field. Here is our table with all the records.
Here minimum mark of each class is displayed. Since we have two
class in our table so the sql command has returned two class with lowest mark in
each of them. We have to use Group
By clause if we ask for the query to return any other field name other than
the min. Otherwise system will generate error.
Getting all the details of the record having minimum ( min ) data
Among the students who got the minimum mark? This is done by using SQL Sub query. Like this .
SELECT * FROM `student` WHERE mark=(select min(mark) from student)
