How to use
- Paste a LINQ query expression into the input box.
- Click Convert to generate a SQL draft.
- Review and adjust joins, provider-specific functions, and null semantics before production use.
Use cases
- Quickly inspect how a LINQ filter maps to SQL predicates.
- Draft SQL for debugging and query-plan analysis.
- Teach core differences between expression chains and SQL clauses.
Limitations and caveats
- Conversion is approximate and optimized for common query shapes.
- Complex joins, grouping, aggregates, and provider-specific functions may need manual refinement.
FAQ
Is the output production-ready SQL?
Treat it as a draft for diagnostics or learning. Complex query semantics still require review.
Does this converter execute my query?
No. It only transforms text and does not connect to a database.
