106. From the following table, write a SQL query to find those employees whose name is six characters in length and the third character must be 'R'. Return complete information about the employees.

Sample table: employees

Sample Solution:

SELECT *
FROM employees
WHERE length(emp_name)=6
  AND emp_name LIKE '__R%';

Sample Output:

 emp_id | emp_name | job_name | manager_id | hire_date  | salary  | commission | dep_id
--------+----------+----------+------------+------------+---------+------------+--------
  69324 | MARKER   | CLERK    |      67832 | 1992-01-23 | 1400.00 |            |   1001
(1 row)

Explanation:

The said query in SQL that selects all columns of employees whose names have a length of 6 characters and start with any two characters, followed by the letter 'R' from the 'employees' table.

With the WHERE clause, the length() function will check if the emp_name has exactly 6 characters, and the LIKE operator will match any two characters following 'R'.
