Hi all

Below is my table
and data

SQL

CREATE TABLE car_uploads(
  location int(3),          -- Location ID
  item varchar(12),         -- Part ID
  quantity int(4)           -- Qty uploaded
);

INSERT INTO car_uploads (location, item, quantity) VALUES(001,'RED CAR',1);
INSERT INTO car_uploads (location, item, quantity) VALUES(002,'RED CAR',3);
INSERT INTO car_uploads (location, item, quantity) VALUES(003,'BLUE CAR',5);
INSERT INTO car_uploads (location, item, quantity) VALUES(002,'BLUE CAR',2);
INSERT INTO car_uploads (location, item, quantity) VALUES(001,'RED CAR',2);
INSERT INTO car_uploads (location, item, quantity) VALUES(002,'RED CAR',5);

below is the code where i am getting the sum of quantity column

SQL

SELECT item,
       SUM(CASE WHEN location = 1 THEN quantity ELSE 0 END) location_001,
       SUM(CASE WHEN location = 2 THEN quantity ELSE 0 END) location_002,
       SUM(CASE WHEN location = 3 THEN quantity ELSE 0 END) location_003,
       SUM(quantity) total,       
  FROM car_uploads
 GROUP BY item,total

now i want the sum of the total (i.e. sum(quantity) as grandtotal.

please tell how to get that..

You can use COMPUTE after your statement eg COMPUTE(SUM(Quantity)) after your group by line

You can also nest this inside another query eg

SQL

Select sum(Quantity) from(SELECT item,
       SUM(CASE WHEN location = 1 THEN quantity ELSE 0 END) location_001,
       SUM(CASE WHEN location = 2 THEN quantity ELSE 0 END) location_002,
       SUM(CASE WHEN location = 3 THEN quantity ELSE 0 END) location_003,
       SUM(quantity) total,       
  FROM car_uploads
 GROUP BY item,total) X

It's giving below error

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM car_uploads GROUP BY item,total) X' at line 6: Select sum(Quantity) from(SELECT item, SUM(CASE WHEN location = 1 THEN quantity ELSE 0 END) location_001, SUM(CASE WHEN location = 2 THEN quantity ELSE 0 END) location_002, SUM(CASE WHEN location = 3 THEN quantity ELSE 0 END) location_003, SUM(quantity) total, FROM car_uploads GROUP BY item,total) X

Well next time you might consider telling us you are using MySQL - the above answer is for MSSQL.
