Hey Marty 

Thanks for reaching out! You can import a SQL script once you are in a document by adding the ERD shape library to your doc and then selecting "Import." I recommend checking out this help center article for more information. Please let me know if you have any other questions! 

You have to have a working database for LucidChart to import the "code" and generate diagram from the query provided by LucidChart. I don't have a working database - I just have SQL code for generating one. Is there no way to import this code into LucidChart to generate the ERD?

Hi Herman

Thanks for your post. Unfortunately what you're describing is not currently possible. In order to create an ERD in Lucidchart you need to run one of the provided queries in a supported DBMS to generate individual diagram shapes from your database schema.
