Generate ER Diagram from SELECT Queries (JOIN Analysis Tool)
SELECT 쿼리에서 ER 다이어그램 자동 생성 (JOIN 분석 도구)
Why it matters
A browser-based tool called SQL2ER generates ER diagrams directly from SELECT queries by analyzing JOIN and ON clauses, without requiring CREATE TABLE statements or any installation. It extracts table relationships from join conditions like table1.column = table2.column and visualizes them, making it useful for understanding legacy systems, code reviews, and debugging complex queries.
