SQL to MongoDB Cheat Sheet
| SQL | MongoDB |
|---|---|
| SELECT * FROM users | db.users.find({}) |
| WHERE age > 25 | { age: { $gt: 25 } } |
| WHERE status IN ("a", "b") | { status: { $in: ["a", "b"] } } |
| WHERE name LIKE "%john%" | { name: { $regex: /.*john.*/i } } |
| ORDER BY name ASC | .sort({ name: 1 }) |
| LIMIT 10 | .limit(10) |
| INSERT INTO t (a) VALUES (1) | db.t.insertOne({ a: 1 }) |
| UPDATE t SET a = 1 WHERE ... | db.t.updateMany({...}, { $set: { a: 1 } }) |
| DELETE FROM t WHERE ... | db.t.deleteMany({...}) |

Frequently Asked Questions
How does SQL to MongoDB conversion work?
This tool parses SQL queries and maps them to equivalent MongoDB operations. SELECT becomes find(), INSERT becomes insertOne(), UPDATE becomes updateMany() with $set, and DELETE becomes deleteMany(). WHERE clauses are converted to MongoDB query filters using operators like $gt, $lt, $in, $regex, etc.
Does this tool support SQL JOIN operations?
MongoDB uses a different data model than relational databases. SQL JOINs are typically handled through MongoDB's $lookup aggregation stage, embedded documents, or application-level joins. This tool converts basic queries; for complex JOINs, consider restructuring your data model for MongoDB.
What SQL WHERE operators are supported?
The converter supports: comparison operators (=, !=, <>, >, <, >=, <=), IN, BETWEEN, LIKE (converted to $regex), IS NULL, IS NOT NULL, AND, and OR. These are mapped to their MongoDB equivalents ($eq, $ne, $gt, $lt, $gte, $lte, $in, $regex, etc.).
Is the converted MongoDB query production-ready?
The converted query provides a solid starting point but may need adjustments for production use. Consider adding indexes for query performance, using proper data types (ObjectId, Date, etc.), and following MongoDB best practices for your specific use case.
