Get multiple count in a single MySQL query for specific column values

For this, you can use aggregate function sum() along with parameter value for specific column. Let us first create a table −

mysql> create table DemoTable1790      (      Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,      Name varchar(20),      Score int      ); Query OK, 0 rows affected (0.94 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1790(Name,Score) values('Chris',45); Query OK, 1 row affected (0.38 sec) mysql> insert into DemoTable1790(Name,Score) values('David',55); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1790(Name,Score) values('David',98); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1790(Name,Score) values('Chris',91); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1790(Name,Score) values('Mike',99); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1790(Name,Score) values('Carol',55); Query OK, 1 row affected (0.35 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1790;

This will produce the following output −

+----+-------+-------+ | Id | Name  | Score | +----+-------+-------+ |  1 | Chris |    45 | |  2 | David |    55 | |  3 | David |    98 | |  4 | Chris |    91 | |  5 | Mike  |    99 | |  6 | Carol |    55 | +----+-------+-------+ 6 rows in set (0.00 sec)

Here is the query to get multiple counts in a single MySQL query −

mysql> select sum(Name='Chris'),sum(Score=55) from DemoTable1790;

This will produce the following output −

+-------------------+---------------+ | sum(Name='Chris') | sum(Score=55) | +-------------------+---------------+ |                 2 |             2 | +-------------------+---------------+ 1 row in set (0.00 sec)
