Supabase is an open-source backend-as-a-service that provides developers with a powerful and scalable database solution. It is built on top of PostgreSQL, offering real-time capabilities, authentication, and a RESTful API, making it an excellent choice for modern web applications.
When working with Supabase Database, you might encounter an error message stating: "Invalid row count in result fetch clause." This error typically arises when executing a SQL query that includes a FETCH clause.
During query execution, the database returns an error, preventing the retrieval of the expected results. This can disrupt application functionality, especially if the query is critical to data processing or user interactions.
The error code 2201X is associated with an invalid row count in the FETCH clause of a SQL query. The FETCH clause is used to limit the number of rows returned by a query, similar to the LIMIT clause in other SQL dialects. However, it requires a valid integer value to specify the number of rows to fetch.
To resolve the error code 2201X, follow these steps:
Examine the SQL query to ensure the FETCH clause is correctly specified. The syntax should be:
SELECT column1, column2 FROM table_name FETCH FIRST n ROWS ONLY;
Replace n with a positive integer value.
Ensure that the row count specified in the FETCH clause is a positive integer. Avoid using non-numeric values or negative numbers.
After making corrections, execute the query again to verify that it runs without errors. Use a SQL client or Supabase's query editor for testing.
