In Databricks SQL, you can select the top row of a result set using the LIMIT clause.

Example:

SELECT *
FROM your_table
ORDER BY some_column
LIMIT 1;

This query will:

1. Select all columns (*) from your_table.
2. Order the results based on some_column (replace with the actual column you want to order by).
3. Limit the output to only the first row after ordering.

Key points:

• If you don’t use ORDER BY, the result might be non-deterministic, as there’s no guaranteed order of rows in a table.
• The LIMIT clause is often used in combination with ORDER BY to get the highest or lowest value based on a specific column.
