Return the name and email of every user on the enterprise plan

Part of WHERE Clause and Comparison Operators in SQL

The problem

Streamhub's account management team is preparing for quarterly enterprise renewal discussions and needs a current subscriber list.

Write a query to return the name and email of every user on the enterprise plan.

Assumptions:

  • The users table contains every registered Streamhub user.
  • The plan column records each user's subscription tier; enterprise customers have plan set to 'enterprise'.

Output:

  • One row per enterprise user, with columns name and email.

The shape

A string-equality filter on plan scopes the user table down to the one tier that matters for the renewal call. Every other plan — free, starter, pro — drops out before the result is shaped.

Clause by clause

  • SELECT name, email returns the two columns the account management team needs to schedule renewal outreach. Both come straight from the users table; no calculation, no transformation.
  • FROM users is the source — every registered Streamhub user, across every plan.
  • WHERE plan = 'enterprise' keeps only rows whose plan value is exactly the string 'enterprise'. The single quotes are required because the value is text; the comparison is case-sensitive, so 'Enterprise' or 'ENTERPRISE' would not match this filter against this column.

Why filter and not return all plans

The users table contains every plan tier mixed together. Without WHERE, the result would be the entire user base, which is the wrong scope for a renewal conversation about the enterprise tier specifically. A query that returns more rows than the business question asked about isn't "safer" — it's wrong in a different direction. The output goes into a renewal-prep deck; free-plan users in that list create work for the team to filter them out by hand.

The same shape recurs for any plan-tier analysis: swap the literal for 'pro', 'starter', or 'free' and the rest of the query stays the same. The structure is constant; the parameter changes.

You practiced filtering on a tier or category column to scope a query to one segment. Plan-tier filters are the everyday shape for any analysis split by subscription level.

Stop guessing whether you actually know it.

SQLMaxx tracks every concept and shows you what you've mastered and what's still shaky. Your skills fill in one concept at a time, so 'I think I get joins' becomes something you can prove.

Spaced review

Learn it once. Keep it for good.

Most of what you learn this week fades by next week. So when a concept comes due for review, SQLMaxx hands you a fresh problem to solve from a blank editor, not a flashcard to re-read. A research-backed spaced-repetition algorithm (FSRS) times each return for right before you'd forget, so your SQL is still there months later, when the interview or the job actually needs it.

Practice, feedback, mastery, review. That's the loop that turns reading into real skill.
