SQL Query Builder

This tool provides a visual model for building SQL queries by selecting tables, configuring joins, and choosing result columns. Users map schemas and relationships without writing SQL, while the generator translates the model into ANSI SQL statements. It supports common clauses such as SELECT, FROM, JOIN, WHERE, GROUP BY, HAVING, ORDER BY, and LIMIT, including nested subqueries and derived expressions. Automatic aliasing prevents collisions, and dialect-aware rules ensure syntax compatibility for PostgreSQL, MySQL, SQL Server, or ANSI SQL. The approach emphasizes correctness and reusability, with a structured export that can be applied in various data projects.\n\nWorkflow-agnostic design: you define a schema context, connect tables through keys, add fields, set filters, and specify aggregations. The tool produces a SQL string and a machine-readable query tree, enabling automation and auditing within data pipelines. Export options include plain SQL and JSON representations that can feed ETL processes or BI tooling. Key differentiators include robust subquery support, consistent alias management, and safe export formats that preserve intent across dialects and environments.\n\nIntended users include developers, DBAs, and data analysts seeking safer, faster query prototyping. Use cases cover exploratory data analysis, reporting, and data integration testing. The tool reduces syntax errors, accelerates iteration, and improves reproducibility by standardizing query construction and export formats across teams.
