Output :
400
Example-2 :
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
