SQL Queries

Question

Table: Salary

 

+————-+———-+

| Column Name | Type     |

+————-+———-+

| id          | int      |

| name        | varchar  |

| sex         | ENUM     |

| salary      | int      |

+————-+———-+

id is the primary key for this table.

The sex column is ENUM value of type (‘m’, ‘f’).

The table contains information about an employee.

 

Write an SQL query to swap all ‘f’ and ‘m’ values (i.e., change all ‘f’ values to ‘m’ and vice versa) with a single update statement and no intermediate temp table(s).

Note that you must write a single update statement, DO NOT write any select statement for this problem
