Foreign Key Lookup On Tumblr Whether you’re debugging a database issue, migrating schema, or documenting relationships, knowing how to list foreign keys for a table or column is critical. in this guide, we’ll explore **four detailed methods** to retrieve foreign key information in mysql, using built in tools like `information schema` and `show` commands. The foreign key constraint is a key used to link two tables together. a foreign key is a field (or collection of fields) in one table that refers to the primary key in another table.
