What does the slash mean in a MySQL query?

The slash means division ( /) in MySQL query. This can be used to divide two numbers. Here, we will see an example to divide numbers from two columns and display result in a new column.

Let us first create a table −

mysql> create table DemoTable719 (    FirstNumber int,    SecondNumber int ); Query OK, 0 rows affected (0.57 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable719 values(20,10); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable719 values(500,50); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable719 values(400,20); Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable719;

This will produce the following output -

+-------------+--------------+ | FirstNumber | SecondNumber | +-------------+--------------+ | 20 | 10 | | 500 | 50 | | 400 | 20 | +-------------+--------------+ 3 rows in set (0.00 sec)

Following is the query to perform division with slash in MySQL −

mysql> select *,FirstNumber/SecondNumber AS Result from DemoTable719;

This will produce the following output -

+-------------+--------------+---------+ | FirstNumber | SecondNumber | Result | +-------------+--------------+---------+ | 20 | 10 | 2.0000 | | 500 | 50 | 10.0000 | | 400 | 20 | 20.0000 | +-------------+--------------+---------+ 3 rows in set (0.00 sec)
