How do I convert SQL to Rails ActiveRecord?

Simply paste your SQL query into our converter tool and click 'Convert to ActiveRecord'. The tool will instantly generate the equivalent Rails ActiveRecord code. Our converter supports all major SQL operations including SELECT, INSERT, UPDATE, DELETE, JOINs, and subqueries.

Is the SQL to ActiveRecord converter free?

Yes, our SQL to ActiveRecord converter is 100% free to use. No sign-up, registration, or credit card required. You can convert unlimited SQL queries to ActiveRecord code instantly.

What SQL queries are supported?

We support all major SQL operations: SELECT queries with WHERE clauses, JOIN operations (INNER, LEFT, RIGHT), INSERT statements, UPDATE operations, DELETE queries, subqueries, aggregate functions (COUNT, SUM, AVG), GROUP BY, ORDER BY, and complex conditional logic.

How accurate is the SQL to ActiveRecord conversion?

Our converter handles most common SQL patterns with high accuracy. For complex queries involving advanced SQL features, we recommend reviewing and testing the generated ActiveRecord code. The tool is continuously improved based on user feedback.

Can I convert PostgreSQL, MySQL, and SQLite queries?

Yes, our converter works with SQL from PostgreSQL, MySQL, SQLite, and other standard SQL databases. ActiveRecord provides database-agnostic query methods that work across different database systems.

Do I need to install anything to use the converter?

No installation required! Our SQL to ActiveRecord converter is a web-based tool that works directly in your browser. Just visit our website, paste your SQL query, and get instant results.

How do I handle complex JOINs in ActiveRecord?

ActiveRecord provides several methods for JOINs: use .joins() for INNER JOINs, .left_joins() for LEFT JOINs, and leverage Rails associations whenever possible. Our converter automatically translates JOIN syntax to the appropriate ActiveRecord methods.

What if my converted ActiveRecord code doesn't work?

First, ensure your Rails models and associations are properly set up. Check that column names match your database schema. For complex queries, you may need to adjust the generated code. Visit our guide for detailed examples and troubleshooting tips.

How do I convert INSERT statements to ActiveRecord?

INSERT statements are converted to ActiveRecord create or new methods. Single inserts become Model.create(attributes), while bulk inserts use Model.insert_all(array_of_attributes). Our converter handles both single and batch operations automatically.

Can I convert UPDATE and DELETE queries?

Yes! UPDATE queries become Model.where(conditions).update_all(changes) or Model.update(id, attributes). DELETE queries are converted to Model.where(conditions).delete_all or Model.destroy(id) depending on the SQL pattern.

What about aggregate functions like COUNT, SUM, AVG?

Aggregate functions are fully supported. COUNT(*) becomes Model.count, SUM(column) becomes Model.sum(:column), AVG(column) becomes Model.average(:column). GROUP BY clauses are converted to .group(:column) chaining.

How are subqueries handled in the conversion?

Subqueries are converted to ActiveRecord's where with subquery syntax or leveraging associations. Complex subqueries might use .where('EXISTS (?)' subquery) or .joins() with nested queries depending on the SQL structure.
