  • Run SELECT queries for data analysis
  • Execute DDL/DML in read-write mode
  • Support for parameterized queries
  • Multi-statement execution with transaction support

​
AI-Powered Prompts

Built-in prompts help AI assistants:
  • Generate optimized SQL queries
  • Explain database elements and relationships
  • Suggest schema improvements
  • Debug complex queries

​
Security Features

  • Read-only Mode: Restrict operations to SELECT queries only
