FAQ: Frequently Asked Questions

  • Can I join multiple tables?

    Yes, you can generate JOIN clauses and link multiple tables using the "Add Join" button.
  • Does it support complex subqueries?

    Currently, it focuses on basic SELECT, JOIN, and WHERE clause generation. For advanced subqueries or window functions, please manually adjust the generated SQL.
  • Do I need to connect a database beforehand?

    No, this tool is an editor for building SQL strings and does not connect to any actual database. It runs entirely in your browser for maximum security.
  • Which SQL dialect is supported?

    It outputs standard ANSI SQL. The generated queries are compatible with most major relational databases like MySQL, PostgreSQL, and SQL Server.
