Syntax error Show row with zero value after addition in MySQL?

Show row with zero value after addition in MySQL?

For this, you can use an aggregate function SUM() along with the condition. Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Status varchar(20)
   -> );
Query OK, 0 rows affected (1.22 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('active');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('active');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('active');
Query OK, 1 row affected (0.30 sec)
mysql> insert into DemoTable values('active');
Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+--------+
| Status |
+--------+
| active |
| active |
| active |
| active |
+--------+
4 rows in set (0.00 sec)

Here is the query to display row with zero value −

mysql> select
   -> sum(Status='active') as 'CountOfActive',
   -> sum(Status='inactive') as 'CountOfInActive'
   -> from DemoTable;

This will produce the following output. Here, for status inactive none of the records are in the table, therefore 0 would be visible −

+---------------+-----------------+
| CountOfActive | CountOfInActive |
+---------------+-----------------+
|             4 |               0 |
+---------------+-----------------+
1 row in set (0.30 sec)
