RPAD in PostgreSQL

In PostgreSQL, the RPAD function doesn't exist. However, you can achieve the same result using a combination of string functions, such as LENGTH, CONCAT, and REPEAT. Here's an example of how to pad a string to the right in PostgreSQL:

SELECT 

    CONCAT(employee_name, REPEAT('*', 15 - LENGTH(employee_name))) AS padded_name

FROM 

    employees;

In this query:

- LENGTH(employee_name) calculates the length of the original employee_name.

- REPEAT('*', 15 - LENGTH(employee_name)) generates a string of asterisks (*) repeated enough times to fill the remaining characters needed to reach a total length of 15 characters, subtracting the length of the original employee_name.

- CONCAT(employee_name, REPEAT('*', 15 - LENGTH(employee_name))) concatenates the original employee_name with the generated padding string.

This query will pad each employee_name with asterisks (*) to make them 15 characters long.
