Supabase is an open-source backend-as-a-service that provides developers with a suite of tools to build applications quickly. It offers a PostgreSQL database, authentication, storage, and real-time subscriptions, making it a powerful choice for modern web and mobile applications.
When working with Supabase Database, you might encounter an error with the code 2201W. This error typically manifests as an invalid row count in the result offset clause, disrupting the execution of your SQL queries.
Developers often observe this issue when attempting to paginate results using the OFFSET clause in SQL queries. The error message might look something like this:
ERROR: 2201W: Invalid row count in result offset clause
The error code 2201W indicates a problem with the OFFSET clause in your SQL query. The OFFSET clause is used to skip a specified number of rows before starting to return rows from the query. This is particularly useful for pagination.
To resolve the 2201W error, follow these steps:
Ensure that the OFFSET value is a non-negative integer. For example, if your query is:
SELECT * FROM users ORDER BY id OFFSET -5;
Change it to:
SELECT * FROM users ORDER BY id OFFSET 5;
Double-check the syntax of your SQL query. Ensure that the OFFSET clause is correctly placed and follows the ORDER BY clause. A valid query should look like this:
SELECT * FROM users ORDER BY id LIMIT 10 OFFSET 5;
Ensure that the OFFSET value is an integer. If you're dynamically generating this value, verify that the variable is correctly cast to an integer.

By following these steps, you should be able to resolve the 2201W error and ensure your queries execute correctly.
