> The clickhouse provides a similar function `mapExtractKeyLike `, and DuckDB has the same function to get the value with the corresponding key. @alamb Thank you -- I found it now [map_extract(map, key)](https://duckdb.org/docs/sql/functions/map.html#map_extractmap-key) Description: Alias of `element_at`. Return a list containing the value for a given key or an empty list if the key is not contained in the map. The type of the key provided in the second parameter must match the type of the map's keys else an error is returned. Example ```sql map_extract(map([100, 5], [42, 43]), 100) ``` *Result*: `[42]` -- This is an automated message from the Apache Git Service.
