How to resolve the issue of the PL/SQL query results no…
In PL/SQL, if the query results are not displayed, it may be due to a few reasons:
- Database connection issue: Make sure you have successfully connected to the database and have permission to execute queries.
- Error in query: Check if your query is correct by executing it independently in an SQL development tool to confirm if it can return results properly.
- Data volume issue: If the query returns a large amount of data, it may result in incomplete or slow display of results, adding conditions to limit the returned data may help.
- Database transaction issue: If a query is in progress and has not been committed or rolled back, it may result in the query results not showing up temporarily. You can try committing or rolling back the current transaction.
- Display issue: sometimes the search results may be hidden or displayed in a different window, you can try checking other windows or refreshing the interface.
If none of the above solutions work, consider re-connecting to the database or restarting the PL/SQL development tool, which may be helpful. If the issue persists, it is recommended to contact the database administrator or technical support for further troubleshooting and resolution.
