The Problem: Importing CSV Files into SQLite
[[See Video to Reveal this Text or Code Snippet]]
However, upon executing this command, you may encounter an error stating:

This can be frustrating, especially when you successfully run the same command in the SQLite command line interface.
Understanding the Issue
Effect of Auto-Commit Mode
Additionally, it's essential to note that SQLite operates in auto-commit mode by default. This means that attempting a single insert per row can be remarkably slow. Each insertion is treated as a separate transaction, which can lead to a significant performance bottleneck, particularly with large datasets.
Enhancing Bulk Insert Performance
Use Batch Inserts
Instead of inserting one row at a time, you can batch your inserts. For example, rather than conducting individual inserts, you can use a single statement to insert multiple rows simultaneously. Here’s an example of how you might structure a batch insert:

Transaction Management
By wrapping your inserts within a transaction, you can enhance performance further. Here’s a simple example of how to implement that:

This approach allows you to group multiple insert operations, leading to improved performance.
Conclusion
By adopting these practices, you'll not only resolve the immediate problem but will also be better equipped to manage large CSV data imports in the future. Happy coding!
