Is There a Best Practice Naming Convention for MySQL Tables and Columns?

Is There a Comprehensive Naming Convention for MySQL?

While various naming practices exist, achieving consistency is paramount in database design. Your proposed conventions provide a solid foundation.

Table Naming:

• Stick to lowercase with underscores for word separation.
• Use singular names (e.g., "foo" instead of "foos").
• Consider adding a suffix for tables containing multiple records of the same type (e.g., "foo_list" or "foo_instances").

Primary Key Naming:

• Employ a self-incrementing primary key.
• Use the convention "tablename_id" (e.g., "foo_id" or "foo_bar_id").

Foreign Key Naming:

• Copy the column name from the referenced table (e.g., "foo_id" in "foo_bar" for a foreign key referencing the primary key of "foo").
• Consider adding a numbered suffix to accommodate multiple references (e.g., "foo_id_1" or "foo_id_2").

Referential Integrity Enforcement:

• Use the syntax "tablename_fk_columnname" (e.g., "foo_bar_foo_id" in the "foo_bar" table).

Additional Considerations:

• Provide consistent index naming, such as "foo_bar_idx1" or "foo_idx1."
• Use singular rather than plural forms for column and table names.
• Maintain consistency throughout all aspects of database naming to ensure organization and ease of maintenance.
