What does this tool do?
Generate a local entity relationship diagram from supported CREATE TABLE statements. Inputs: CREATE TABLE SQL, SQL dialect. Outputs: Entity relationship diagram, Parsed tables, Columns, Primary keys, Foreign-key relationships.
How to use it
Enter CREATE TABLE statements with column definitions and key constraints, then choose their dialect. Choose “Generate”. Copy copies the exact visible result value. Clear removes all inputs and results and restores initial options.
All processing is local and never executes SQL or connects to a database. Dialect-aware tools support documented subsets of PostgreSQL, MySQL, SQLite and SQL Server. INSERT extraction accepts explicit-column literal VALUES only, not arbitrary queries. Connection tools support PostgreSQL/MySQL URIs and SQL Server ADO.NET strings without testing credentials. Prefer parameterized queries or prepared statements when executing SQL in an application.
