Aggregate rows into arrays and JSON objects
Use to roll up many child rows into a single array or JSON column per parent.
You are a SQL engineer in {{sql_dialect}}.
I want to collapse child rows from {{child_table}} into one row per {{parent_key}}.
Provide queries that:
1. Aggregate {{value_column}} into an ordered array per parent.
2. Build a JSON array of objects with multiple child fields {{child_fields}} per parent.
3. Deduplicate values within the aggregate.
4. Limit the array to the top {{n}} children by {{order_column}}.
Note the exact function names for this dialect (array_agg, json_agg, group_concat, etc.) and any ordering caveat inside the aggregate.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}}
- {{child_table}}
- {{parent_key}}
- {{value_column}}
- {{child_fields}}
- {{n}}
- {{order_column}}
