Get total in the last row of MySQL result?
To get total in the last row of MySQL result, use the following syntax −
( SELECT yourColumnName1, yourColumnName2, yourColumnName3, . . N FROM yourTableName ) UNION ( SELECT "yourMessage" AS anyAliasName1, SUM(yourColumnName1) AS anyAliasName2, SUM(yourColumnName2) AS anyAliasName3, . . N FROM yourTableName );
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table ProductDemo -> ( -> ProductId varchar(10), -> ProductQuantity int, -> ProductValue int -> ); Query OK, 0 rows affected (0.63 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into ProductDemo values('Product-1',10,300);
Query OK, 1 row affected (0.10 sec)
mysql> insert into ProductDemo values('Product-2',5,200);
Query OK, 1 row affected (0.17 sec)
mysql> insert into ProductDemo values('Product-3',7,340);
Query OK, 1 row affected (0.13 sec)
mysql> insert into ProductDemo values('Product-4',20,500);
Query OK, 1 row affected (0.10 sec)
mysql> insert into ProductDemo values('Product-5',30,1000);
Query OK, 1 row affected (0.42 sec)
Display all records from the table using a select statement. The query is as follows −
mysql> select *from ProductDemo;
The following is the output −
+-----------+-----------------+--------------+ | ProductId | ProductQuantity | ProductValue | +-----------+-----------------+--------------+ | Product-1 | 10 | 300 | | Product-2 | 5 | 200 | | Product-3 | 7 | 340 | | Product-4 | 20 | 500 | | Product-5 | 30 | 1000 | +-----------+-----------------+--------------+ 5 rows in set (0.00 sec)
Here is the query to get total in the last row of MySQL result −
mysql> (SELECT ProductId, -> ProductQuantity, -> ProductValue -> FROM ProductDemo) -> UNION -> (SELECT "Total" AS ProductName, -> SUM(ProductQuantity) AS TotalQuantity, -> SUM(ProductValue) AS TotalValue -> FROM ProductDemo);
Output
+-----------+-----------------+--------------+ | ProductId | ProductQuantity | ProductValue | +-----------+-----------------+--------------+ | Product-1 | 10 | 300 | | Product-2 | 5 | 200 | | Product-3 | 7 | 340 | | Product-4 | 20 | 500 | | Product-5 | 30 | 1000 | | Total | 72 | 2340 | +-----------+-----------------+--------------+ 6 rows in set (0.00 sec)
