Code:
-- This SQL query selects the first name and last name of employees whose last name contains the letter 'C' after the second position.
SELECT
first_name, last_name -- Selecting the first name and last name from the employees table.
FROM
employees -- Specifies the table from which data is being retrieved, in this case, it's the 'employees' table.
WHERE
INSTR(last_name,'C') > 2; -- Filters the rows where the letter 'C' is found in the last name after the second position.
Explanation:
- The SELECT statement retrieves the first name and last name from the specified table (employees).
- The WHERE clause filters the rows based on a condition.
- The INSTR() function is used to find the position of the first occurrence of the letter 'C' in the last_name.
- The condition INSTR(last_name,'C') > 2 ensures that the letter 'C' is found after the second position in the last name.
- Rows meeting this condition are selected for output.
Sample Output:
first_name last_name Neena Kochhar Nandita Sarchand Peter Tucker
