RPAD in Greenplum

In Greenplum, there isn't a built-in RPAD function like in some other SQL databases. However, you can achieve the same functionality using the LPAD function by padding characters to the left and then reversing the result. Here's how you can do it with an example:

Suppose you have a table employees with a column employee_name, and you want to pad each name to a length of 15 characters with asterisks (*) to the right:

SELECT 

    REVERSE(SUBSTRING(REVERSE(LPAD(employee_name, 15, '*')), 1, 15)) AS padded_name

FROM 

    employees;

In this query:

- LPAD(employee_name, 15, '*') pads each employee_name to the left with asterisks (*) to a total length of 15 characters.

- REVERSE reverses the padded string.

- SUBSTRING extracts the last 15 characters of the reversed padded string.

- REVERSE reverses the result again to get the original order.

This query will produce a result where each employee_name is padded with asterisks (*) to a length of 15 characters.
