Troubleshooting
Even when using robust database tools, you may occasionally encounter errors while interacting with your data. Understanding what these errors mean and how to address them helps you keep your application running smoothly.
This guide covers the most common error types you might see and provides steps to resolve them.
We categorize errors based on their origin. Identifying the specific error type is the first step toward a quick fix.

When a "Query Error" occurs, the system indicates that it could not successfully execute a command against your database. This is often due to a mismatch between what you requested and how your database expects the data to be formatted.
Examine the command text provided in the error details. Ensure that your syntax matches the requirements of your specific database type.
Verify that the values you are passing—such as ID numbers, strings, or dates—match the expected format for your database tables.
Look for the underlying error message included with the failure. It often contains the specific reason the database rejected the command, such as a connection timeout or a missing table reference.
Tip
If you are unsure why a query is failing, try running a simpler version of the command to isolate the issue.
A "Rollback" error occurs when you have initiated a group of database actions (a transaction) but they were cancelled before being saved to the database. This is a intentional safety feature used to keep your data consistent; if one part of a multi-step task fails, the system reverses all changes to ensure the database stays in a clean, accurate state.
Important
A TransactionRollbackError is not always a sign of a bug; it often means your code successfully prevented an incomplete or invalid data update.
If you encounter an error you cannot explain, follow this simple workflow to diagnose the problem.
Warning
Always ensure you have a backup of your data before performing large-scale troubleshooting or complex manual data operations.
Note
If the error persists after verifying your inputs, ensure your database connection is active and that your user account has the necessary permissions to perform the requested actions.
