Your question is Date Format Conversion in SQL. Start with the requirements and the one table on the right.

Run and submit as often as you like. When you're ready, talk me through your approach or go straight to the code.

You need to log in / sign up to run or submit.

Problem

Mphasis reporting teams need service dates displayed consistently in client-facing operational reports. The source values are stored as PostgreSQL DATE values, which normally display as YYYY-MM-DD.

Write a SQL query against the service_requests table that converts each request_date to the MM/DD/YYYY format using PostgreSQL's built-in TO_CHAR function.

Requirements

  1. Return the request identifier and the formatted date.
  2. Preserve rows where request_date is NULL, returning NULL for the formatted value, and order the results by request_id.
