Cohort Retention Analysis AI Prompt
Cohort Retention Analysis is a intermediate template for sql. This prompt is meant to generate production-usable SQL for analytical tasks. It gives the AI enough direction to build a query that is not only correct, but also readable, structured, and adapted to the database engine or business question. Use it when you want a query you can review, run, and modify with minimal rework. It is structured as a reusable template, so placeholders can be filled in for a specific table, metric, or business context. The requested output can include more technical detail, prioritization, and interpretation while still staying practical.
Prompt text
Write a SQL cohort retention analysis using the table {{table_name}} in {{database_type}}.
Definitions:
- Cohort: the month of a user's first {{cohort_event}} recorded in {{date_column}}
- Retention: whether the user performed {{retention_event}} in each subsequent month
The query should:
1. Define cohorts using a CTE that finds each user's first event month
2. Join back to activity data to find which months each user was active
3. Calculate cohort size and retention count per month offset (0, 1, 2, ... N)
4. Return a cohort × month offset matrix with retention percentages
Include comments on each CTE. Database: {{database_type}}.When to use this prompt
Use case 02
When you need SQL that follows a clear analytical structure with comments.
Use case 03
When you are working across different databases and need engine-specific wording.
Use case 04
When you want a reusable query pattern for profiling, retention, funnels, or forecasting inputs.
What the AI should return
The AI should return a complete SQL query or query set that is ready to review and adapt. It should use comments, readable CTE names, and clear formatting so the logic is easy to follow. If assumptions are required, they should be stated briefly before or after the query. The result should be practical enough that an analyst can copy it into their SQL editor with minimal cleanup.
