Chapter 21. MySQL Workbench Schema Validation Plugins
(Commercial Version)
MySQL Workbench provides validation modules so that you can test your models before implementing them.
The validation plugins are accessed from the MODEL menu option. One plugin performs general validation for any Relational Database
Management System (RDMS) and the other is MySQL-specific. Beneath these menu items are a number of specific validation
tests. Running any one of these tests opens an output window docked at the bottom of the application. Warning messages are displayed
on the left side of this window and the tests performed are displayed on the right.
The tasks performed by the validation modules are outlined in what follows.
21.1. General Validation
The types of validation and examples that violate validation are listed in what follows:
• Empty Content validation
• A table with no columns
• A routine or view with no SQL code defined
• A routine group containing no routines
• A table, view, or routine not referenced by at least one role
• A user with no privileges
• Objects such as tables that do not appear on at least one EER Diagram
• Table Efficiency Validation
• A table with no primary key
• A primary key that does not use an integer-based data type
• A foreign key that refers to a column with a different data type
• Duplicated Identifiers Validation
• Duplicate object names
• Duplicate role or user names
• Duplicate index or routine names
• Consistency Validation
• Use of the same column with columns of differing data types
• Logic Validation
• A foreign key that refers to a column other than the primary key in the source table
• Any object that is object is either read- or write-only by role definition
• Placeholder objects left over from reverse engineering
21.2. MySQL-Specific Validation
The types of MySQL-specific validation and examples that violate validation are listed in the following.
• Integrity Violation
• An object name longer than the maximum allowed
