NL2SQL ENGINE

Natural Language to SQL:Ask Your DatabaseQuestions in Plain English

No SQL syntax needed. Just ask questions naturally,
and UnifySQL's NL2SQL engine generates precise, optimized queries from your schema context.

NL2SQLCapabilities

More than just text conversion -- a true database conversation engine

Schema Intelligence

The AI deeply understands your database schema -- tables, columns, relationships, foreign keys, and indexes -- before generating any query.

Conversation Mode

Ask follow-up questions naturally. The AI remembers context from previous queries so you can refine results conversationally.

Automatic Join Detection

No need to specify JOINs. The AI detects relationships between tables and automatically constructs the correct join paths.

Multi-Turn Queries

Build complex analyses step by step. Start simple and progressively add filters, aggregations, and transformations through conversation.

How SchemaIntelligence Works

The secret behind enterprise-grade NL2SQL accuracy

1

Introspects Your Schema

Automatically scans all tables, columns, data types, constraints, and relationships in your database.

2

Learns Naming Conventions

Understands your team's naming patterns so 'users' and 'customers' are correctly mapped to your actual table names.

3

Maps Relationships

Builds a graph of foreign keys and implicit relationships to determine the optimal join paths.

4

Optimizes for Your Engine

Generates dialect-specific SQL with engine-optimized functions, syntax, and performance hints.

Built ForEvery Role

Natural language queries empower your entire team

Data Analysts

Ask complex business questions without writing a single line of SQL. Get instant answers with visualizations.

EXAMPLE QUERY

"What was our monthly revenue trend by product category for the last 6 months?"

Product Managers

Query user behavior and product metrics directly. No more waiting for engineering to pull data.

EXAMPLE QUERY

"How many users completed onboarding this week vs last week?"

Backend Engineers

Speed up debugging and data exploration. Quickly find records, check data integrity, and explore schemas.

EXAMPLE QUERY

"Show me all orders with status 'pending' that were created more than 24 hours ago"

Frequently Asked Questions

Everything most teams ask before getting started.

Natural Language to SQL (NL2SQL) is an AI technology that converts questions written in plain English into SQL queries. Instead of learning SQL syntax, you simply describe what data you need -- like asking a question to a colleague -- and the AI generates the correct SQL query automatically.

Academic NL2SQL benchmarks test on generic, well-known schemas. UnifySQL's NL2SQL is schema-aware -- it connects to your actual database, learns your specific tables, relationships, and naming conventions. This real-world context produces significantly higher accuracy than benchmark-trained models on your production data.

Yes. UnifySQL supports multi-turn conversational queries. You can ask an initial question, then refine results with follow-ups like 'now filter that by region' or 'show me the same data but grouped by month.' The AI maintains full context throughout the conversation.

Absolutely. UnifySQL's NL2SQL automatically detects table relationships and generates multi-table JOINs, subqueries, CTEs, window functions, and complex aggregations. You don't need to specify how tables connect -- the AI figures out the optimal join path from your schema.

Yes. UnifySQL processes queries locally and only sends schema metadata (table and column names) to the AI engine -- never your actual data. All connections are encrypted, and enterprise plans support on-premise AI deployment for maximum security.

UnifySQL's natural language to SQL feature supports PostgreSQL, MySQL, Microsoft SQL Server, MariaDB, MongoDB, and Cassandra. The AI generates dialect-specific syntax optimized for each database engine.
