product_1 VARCHAR(10),
product_2 VARCHAR(10),
price int

Using MIN() function and finding the minimum value of the stated float values.

CREATE TABLE floats
(  
user_id int IDENTITY(100, 2) NOT NULL,
float_val float
);
INSERT floats(float_val)  
VALUES (3.5);

INSERT floats(float_val)  
VALUES (2.1);

INSERT floats(float_val)  
VALUES (6.3);

INSERT floats(float_val)  
VALUES (9.0);

INSERT floats(float_val)  
VALUES (7.0);

SELECT MIN(float_val) FROM floats;

Output :

2

Example-3 :

Using MIN() function and getting the output where MRP is greater than the minimum of all the MRP’s.

CREATE TABLE package
(  
user_id int IDENTITY(100, 4) NOT NULL,  
item VARCHAR(10),
mrp int  
);
INSERT package(item, mrp)  
VALUES ('book1', 3);

INSERT package(item, mrp)  
VALUES ('book2', 350);

INSERT package(item, mrp)  
VALUES ('book3', 400);

SELECT * FROM package
WHERE mrp > (SELECT MIN(mrp) FROM package);

Output :

  | user_id  | item     | mrp
--------------------------------
1 | 100      | book2    | 350
--------------------------------
2 | 104      | book3    | 400

Example-4 :

Using MIN() function and getting the minimum value of all the (MRP-sales price) values.

CREATE TABLE package
(  
user_id int IDENTITY(100, 4) NOT NULL,  
item VARCHAR(10),
mrp int,
sp int
);
INSERT package(item, mrp, sp)  
VALUES ('book1', 250, 240);

INSERT package(item, mrp, sp)  
VALUES ('book2', 350, 320);

INSERT package(item, mrp, sp)  
VALUES ('book3', 400, 350);

SELECT MIN(mrp-sp) FROM package;

Output :

10
