SQL to MongoDB Query Converter

What is this SQL to MongoDB Converter?

This tool helps you translate your standard SQL (Structured Query Language) queries into the equivalent query syntax used by MongoDB, a popular NoSQL document database. It is designed for developers transitioning or working with both relational databases and MongoDB.

Enter your SQL query in the input box, and the corresponding MongoDB query will be generated below. Thanks to an advanced SQL parser, this tool can now handle more complex queries including basic aggregations and varied WHERE clauses.

Why Convert SQL to MongoDB?

• Learning MongoDB: Understand how familiar SQL concepts map to MongoDB's query language.
• Migration Projects: Get a starting point when migrating applications from SQL databases to MongoDB.
• Quick Snippets: Generate MongoDB query equivalents for common SQL operations quickly.

Supported SQL Operations (Enhanced)

This converter leverages an SQL parsing library to support a broader range of SQL operations:

• SELECT fields FROM table WHERE conditions ORDER BY field LIMIT n OFFSET m
• SELECT COUNT(*), SUM(field), AVG(field), MIN(field), MAX(field) FROM table GROUP BY field1, field2 HAVING conditions
• INSERT INTO table (field1, field2) VALUES (value1, value2), (value3, value4)
• UPDATE table SET field1 = value1 WHERE conditions
• DELETE FROM table WHERE conditions

Supported Operators: =, != (<>), >, >=, <, <=, IN, NOT IN, LIKE (con % e _), IS NULL, IS NOT NULL.

Logical Operators: AND, OR, parentesi () per raggruppare le condizioni. NOT ha un supporto limitato.

Limitations: Complex JOIN operations (which require $lookup in MongoDB and often a schema redesign understanding), most subqueries, window functions, common table expressions (CTEs), and database-specific SQL functions or procedures are generally not supported or have very limited translation. For these, manual translation to the MongoDB Aggregation Framework or application logic is recommended.
