Customer Lifetime Value Query AI Prompt
Customer Lifetime Value Query is a advanced 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 should be comprehensive, methodical, and suitable for expert review or production-style work.
Prompt text
Write a SQL query to calculate customer lifetime value (LTV) from the transactions table {{table_name}} in {{database_type}}.
The query should compute per customer:
- First purchase date and most recent purchase date
- Total number of orders
- Total revenue
- Average order value
- Purchase frequency (orders per month since first purchase)
- Predicted LTV using the formula: avg_order_value × purchase_frequency × customer_lifespan_months
Also segment customers into LTV tiers: Top 10%, Mid 40%, Bottom 50%.
Return one row per customer with all metrics and the LTV tier label.
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.
