Supabase is an open-source backend-as-a-service that provides developers with a suite of tools to build applications quickly. It offers a real-time database, authentication, storage, and more, all built on top of PostgreSQL. Supabase aims to simplify the development process by providing a scalable and secure backend infrastructure.
When working with Supabase Database, you might encounter an error code 22025, which indicates an 'Invalid escape sequence error in a LIKE pattern.' This error typically arises when executing SQL queries that involve pattern matching using the LIKE operator.
Developers often use the LIKE operator to search for patterns within text fields. However, if the escape sequences within the pattern are not correctly formatted, it can lead to this error.
The error code 22025 is specific to PostgreSQL, which is the underlying database engine for Supabase. This error occurs when the escape sequence in a LIKE pattern is not valid. For example, using a backslash (\) without specifying an escape character can trigger this error.
In SQL, the LIKE operator is used for pattern matching. Special characters like % and _ are used as wildcards. To include these characters literally in a pattern, an escape character must be defined. If the escape sequence is incorrect, PostgreSQL will raise an error.
To resolve the 22025 error, follow these steps:
Review the SQL query that triggered the error. Look for the LIKE clause and identify any escape sequences used.
Ensure that the escape sequence is correctly formatted. If you need to use a backslash, specify an escape character using the ESCAPE keyword. For example:
SELECT * FROM table_name WHERE column_name LIKE '%\_%' ESCAPE '\';
In this example, the backslash is used as an escape character to treat the underscore as a literal character.
After correcting the escape sequence, execute the query again to ensure that the error is resolved. Verify that the query returns the expected results.
For more information on using the LIKE operator and escape sequences in PostgreSQL, refer to the official PostgreSQL documentation.
