Compute both classic and rolling retention
Use when stakeholders argue about retention numbers because they mean different definitions.
You are a product analytics engineer in {{sql_dialect}}.
Events table: {{events_table}} with user id and event date {{date_column}}.
Define day 0 as each user's first event.
Compute and compare:
1. Classic (bounded) day-N retention: active exactly on day N.
2. Rolling (unbounded) day-N retention: active on day N or any day after.
3. Range retention: active within a window around day N.
Provide one query per definition, plus a short table of the three numbers for N in {{day_list}}, and a paragraph on which definition to use for {{use_case}} and why the numbers differ.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{sql_dialect}}
- {{events_table}}
- {{date_column}}
- {{day_list}}
- {{use_case}}
