PostgresDB 20000: Case Not Found

What is PostgresDB 20000: Case Not Found

Verify the query syntax: Ensure that your query is correctly written and that you're querying the right table and column names. Typographical errors or referencing non-existent tables or columns can lead to issues. Example: SELECT * FROM your_table_name;Check if the case (row) actually exists: Use a SELECT statement to check if the data you're looking for is present in the database.Example: SELECT * FROM your_table WHERE case_id = 'your_case_id';Review database logs for errors: Look for any related error messages that might have occurred around the time you encountered the "Case Not Found" error. This can provide clues on what went wrong.Command: SELECT * FROM pg_catalog.pg_logs WHERE log_time >= 'your_error_time';Examine the application code: If applicable, review the part of your application code that generates the query. There might be conditions where the case ID is not correctly passed or constructed in the query.If you suspect the issue might be related to data inconsistency or corruption, consider running a data integrity check.Command: REINDEX TABLE your_table_name; Note: Use with caution and ideally during low-traffic periods, as it may impact database performance.Check connection parameters: Ensure that your database connection parameters (host, database name, credentials) are correct and that you're connecting to the expected database.If using stored procedures or functions that might generate this error, review their definitions to ensure they are correctly implemented.Example: SELECT prosrc FROM pg_proc WHERE proname = 'your_procedure_name';Ensure that your database user has the correct permissions to access the data it's trying to query.Command: SELECT grantee, privilege_type FROM information_schema.role_table_grants WHERE table_name='your_table_name';Check if there's any trigger or rule that might be intercepting the operation and causing the error.Command to check triggers: SELECT * FROM pg_trigger WHERE tgrelid = 'your_table_name'::regclass;Finally, if none of the above steps help, consider restoring the data from a backup if the missing case is critical and supposed to exist. Ensure to follow proper procedures to avoid data loss. Note: This step should be considered carefully, especially if you're not experienced with database administration.
