How to Verify Primary and Foreign Key Constraints on Tables in MySQL

As you're trying to establish primary and foreign key relationships between tables, you'll want to confirm these constraints have been set correctly. To do this, you can use the convenient MySQL command:

SHOW CREATE TABLE table_name;

For instance, to inspect the constraints on the "practices" and "cred_insurances" tables within your "credentialing1" database, you would execute the following commands:

SHOW CREATE TABLE practices;
SHOW CREATE TABLE cred_insurances;

The output of these commands will provide you with the SQL statements required to recreate the tables, including details on all columns, data types, and importantly for your purpose, constraint information. This includes not only primary and foreign key constraints but also information on table type, character set, and other settings.

With this command, you can easily verify the constraints you intended to establish, ensuring the integrity of your database relationships.
