Enhance SQL Model Error Messages With Context And Guidance

by ADMIN 59 views

Summary

When a SQL model fails to build in Rill due to syntax or reference errors, the error messages shown to users are often minimal and lack actionable context. This makes troubleshooting difficult, especially for new users or those unfamiliar with DuckDB SQL. The current error messages do not indicate the exact line or position of the error, lack suggestions for common SQL mistakes, and do not link to relevant documentation.

Problem Description

Currently, when a SQL model contains an error (e.g., missing comma, invalid reference), the error message is generic and does not provide sufficient information to help users debug the issue. The error message does not indicate the exact line or position of the error, which makes it difficult for users to identify the problematic code. Additionally, the error message lacks suggestions for common SQL mistakes, which can lead to frustration and a longer debugging time. Furthermore, the error message does not link to relevant documentation, such as Rill or DuckDB SQL guides, which can provide users with the necessary information to resolve the issue.

Current Error Message

When a SQL model contains an error, the error message is displayed as follows:

Error: SQL model failed to build due to syntax error

This error message does not provide any information about the exact line or position of the error, making it difficult for users to identify the problematic code.

Steps to Reproduce

To reproduce the issue, follow these steps:

  1. Initialize a new Rill project using the command rill init --project my-project.
  2. Add a data source to the project.
  3. Create a SQL model with a syntax error (e.g., SELECT id name FROM my_table - missing comma).
  4. Run rill start to build the project.

Observed Behavior

When you run rill start to build the project, the error message is displayed as follows:

Error: SQL model failed to build due to syntax error

The error message does not indicate the exact line or position of the error, making it difficult for users to identify the problematic code.

Expected Behavior

The expected behavior is that the error message should indicate the exact line or position of the error, suggest possible fixes for common SQL errors, and link to relevant documentation.

Suggested Solution

To improve the error handling in Rill, we suggest the following changes:

Improve Error Handling in SQL Parser

Improve the error handling in the SQL parser to capture and display line numbers and code context. This will enable users to identify the exact line or position of the error and provide a clear understanding of the problematic code.

Add Logic to Recognize and Suggest Fixes for Frequent SQL Mistakes

Add logic to recognize and suggest fixes for frequent SQL mistakes, such as missing commas, mistyped keywords, and invalid references. This will help users to quickly identify and resolve common SQL errors.

Provide Direct Links to Rill and DuckDB Documentation

Provide direct links to Rill project errors docs and DuckDB SQL syntax documentation. This will enable users to quickly access relevant documentation and resolve the issue.

Show Highlighted Snippet of SQL Code Around the Error

Show a highlighted snippet of the SQL code around the error. This will enable users to quickly identify the problematic and understand the context of the error.

Impact

The suggested solution will have a significant impact on the user experience of Rill. With improved error handling, users will be able to quickly identify and resolve common SQL errors, reducing the debugging time and increasing the productivity. Additionally, the suggested solution will provide better onboarding for new users and those less familiar with SQL or DuckDB, reducing the basic support requests.

Faster, Easier Debugging

The suggested solution will enable users to quickly identify and resolve common SQL errors, reducing the debugging time and increasing the productivity.

Better Onboarding for New Users

The suggested solution will provide better onboarding for new users and those less familiar with SQL or DuckDB, reducing the basic support requests.

Fewer Basic Support Requests

The suggested solution will reduce the basic support requests by providing users with the necessary information to resolve common SQL errors.

Conclusion

In conclusion, the current error messages in Rill are minimal and lack actionable context, making troubleshooting difficult for users. The suggested solution will improve the error handling in Rill, providing users with the necessary information to quickly identify and resolve common SQL errors. With improved error handling, users will be able to quickly identify and resolve common SQL errors, reducing the debugging time and increasing the productivity. Additionally, the suggested solution will provide better onboarding for new users and those less familiar with SQL or DuckDB, reducing the basic support requests.

Frequently Asked Questions
