You can use count(1). Let us first see the syntax −
select count(1) from yourTableName;
Let us first create a table −
mysql> create table DemoTable ( StudentName varchar(100) ); Query OK, 0 rows affected (0.84 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(StudentName) values('John Smith'); Query OK, 1 row affected (0.24 sec) mysql> insert into DemoTable(StudentName) values('Chris Brown'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(StudentName) values('David Miller'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable(StudentName) values('Carol Taylor'); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+--------------+ | StudentName | +--------------+ | John Smith | | Chris Brown | | David Miller | | Carol Taylor | +--------------+ 4 rows in set (0.00 sec)
Following is the query to get number of rows in a table without using count(*) −
mysql> select count(1) from DemoTable;
Output
+----------+ | count(1) | +----------+ | 4 | +----------+ 1 row in set (0.03 sec)
