SQL Insert Batch Optimizer

Why Use Batch Inserts?

Executing thousands of individual INSERT statements is one of the most common performance bottlenecks in database operations. Each single INSERT requires a complete round-trip to the database server: connection overhead, query parsing, execution planning, and transaction commits. This process can take 10-50ms per statement, meaning 10,000 individual inserts could take 100-500 seconds!

Batch inserts solve this by combining multiple value sets into a single INSERT statement. Instead of 10,000 round-trips, you make just 100 (with batch size of 100). This reduces network overhead, allows the database to optimize execution plans, and can improve performance by 10-50x. Modern databases like MySQL, PostgreSQL, and SQL Server are specifically optimized for batch operations.

How to Use the Tool

1. Paste your individual INSERT statements into the left editor. Copy them directly from your scripts or logs.
2. Adjust the batch size according to your database limits (100 is safe for most engines).
3. Click Convert to generate optimized batches.
4. Use the Copy button to grab the output and run it in your environment.

Tip: if your tables include optional columns, ensure every INSERT keeps the same column order before converting.
