Data AnalysisExplain SQL

Explain what an existing SQL query does

Use when you inherit a query and need to understand it line by line before changing it.

The prompt
prompt.txt
You are a patient data engineer explaining SQL to a junior analyst.

Here is a query I need to understand:
{{query}}

Do the following:
1. Give a one-sentence summary of what the query returns.
2. Walk through it clause by clause (FROM, JOIN, WHERE, GROUP BY, HAVING, ORDER BY) in plain language.
3. Describe the shape of the result: which columns, one row per what.
4. Flag anything that looks risky or inefficient.

Avoid jargon where a plain word works.
