Model Verification

Features and Tools > Tools > Model Verification

Toad Data Modeler allows you to verify your models. You can choose the items you want to verify, find out what errors and flaws your model contains and use quick fixes to resolve any issues.

To verify your model

  1. Select  Model Menu | Verify Model... (also CTRL+F9).
  2. On the Model Objects tab you can mark items for verification. Select either entire object group types or single objects.
  3. On the Verification Settings tab select the rules that should be part of the verification. To save the settings, click Save & Verify.
  4. The result of the Model Verification is shown in Verification Log, which is displayed automatically. To display the log manually, select Windows Menu | Verification Log. Objects that did not pass the verification are also marked by error/warning icons in Model Explorer.

Model Verification Form

Model Objects tab - lists all objects and object group types in your model. Checked object are those that will be verified.

Verification Settings tab - Here you can enable/disable rules that should be considered during verification. Use the buttons on the top of the form to check/uncheck all errors/warnings/hints at once.

Rules are database dependent, the following screenshot shows rules for Microsoft SQL Server 2012.

Verification Log

Verify Model results are displayed in Verification Log.

Toad Data Modeleroffers Quick Fixes - recommended solutions for problems and issues found by Model Verification. Quick Fixes are accessible for problematic objects both in Verification Log and Physical Model Explorer, in right-click menu.

The Verification Log toolbar contains several buttons:

Button Option Description
Tree View Switches Verification Log to tree view where the problem description, affected objects and quick fix suggestion can be all seen. Note that you cannot ignore messages or remove them from ignored in this view.
Show Errors/Warnings/Hints When enabled, Errors/Warnings/Hints are shown in Verification Log.
Ignore Message Marks the selected message as ignored.
Remove Message from Ignored Removes the selected message from ignored list.
Show Ignored Messages

Shows/hides ignored messages.

Verify Form Displays Model Verification dialog.
Verify Verifies model using the last saved settings.
Save Verification Log Saves all verification messages (including the ignored ones) to a CSV file.

On Form Verification

Errors, warning and hints can be displayed directly in the Object Properties form, at the bottom. Every time you make changes to the object and confirm, the object is verified and all issues are displayed at the bottom, similar to the screenshot below. Quick Fixes are not available in this mode.

On Form Verification can be enabled/disabled in Settings Menu | Options | Model . You can also decide what kind of verification messages should be shown - errors/warning/hints.

Syntax Validity

SQL Preview tab now highlights errors in SQL script syntax.

  • Check Syntax Validity to perform syntax checks in SQL Preview for the following objects:
    • Procedure, Function, View, Materialized View
    • User Data Type, Package (Oracle only)
  • Options are available in Options | Model | Physical Model | Verification | SQL Syntax Options
  • Syntax Validity check is supported for the following databases:
    • IBM DB2 LUW, IBM DB2 z/OS, Microsoft Azure SQL Database, Microsoft SQL Server, MySQL, Oracle, PostgreSQL, SAP Anywhere, SAP ASE, SAP IQ, Teradata


Model Verification can be configured for each specific database. Go to Settings Menu | Options | Model | Physical Model | *Target Database*.

In the Verificator frame you can enable/disable verification rules or change their category, e.g. Empty Object can be shown as an error instead of warning.

Syntax validity check may be disabled in Settings | Options | Model | Physical Model | <database> | Syntax Validity checkbox


Refactoring Utility

Features and Tools > Tools > Refactoring Utility

Toad Data Modeler provides you with a tool that is able to refactor all references to an object when you change its name. For example, let's say you've changed name of an entity. Usually, you would have to go through the rest of the model and change the name in all the places where it is referenced. Refactoring Utility is able to do this automatically, saving your time.

Note: The utility refactors text properties only (e.g. AfterScript, BeforeScript, SQL tab, text Views...)

To open Refactoring Utility

Go to Tools Menu | Refactoring Utility.

  • In section Previously Renamed Object (top-right), you can find objects that were renamed.
  • In section Objects to Modify, you can find objects and properties that contain old names.
  • In section Current Code, the body of SQL code is shown.
  • Use buttons Previous Term and Next Term to move between names in the same code.
  • Section Preview of Modified Code displays a preview of refactored code. You can click any of the highlighted names and select old or new name or use the icons in middle column to reject suggested changes.

Schema/Owner/Database Assignment

Features and Tools > Tools > Schema/Owner/Database Assignment

This tool allows you to assign or remove schema/owner/database to/from multiple object groups in your model at once.

To assign a schema/owner to your model

Select Tools | Schema/Owner Assignment.

Option Description

Select Schema/Owner/Database

Contains existing Schemas/Owners/Users in your model.

Select --None-- from the list to remove the existing schema from objects you mark in the Select types of objects section.

Assign to objects where value is not defined

Assigns schema/owner to objects, which have none assigned yet.

Confirm before assignment checkbox

Confirmation dialog for each object where schema is being assigned/removed will be displayed.

Select types of objects area

Mark objects which should be assigned a Schema/Owner.

Infer Relationships

Features and Tools > Tools > Infer Relationships

This feature tries to map Primary Keys or Alternate Keys to identically named attributes in other entities.


  • Mapping is performed between key and non-key attributes. In other words, if identically named attributes are part of primary key in various tables, e.g. ID column in table Customer and ID column in table Order, the two ID columns will not be mapped and no relationship will be created.
  • Names must be identical and data type must be the same, including parameters.
  • Non-identifying relationships are created by default. In case you need an identifying relationship, edit the automatically added relationship and change its type to identifying manually.

To run the Infer Relationship function

Select Tools | Infer Relationship.

Note: Relationships created this way will be marked with a To-Do task prompting you to check whether the relationship has been created correctly.


Model with no relationships. See the Customer ID column in tables Customer and Order Record.
In table Film there is an alternate key with two columns Title and Director. Identically named columns are in table Customer Rating.

Run the Infer Relationship function and see the result:

Infer Relationships and Reverse Engineering

The same tool can be used automatically during reverse engineering.

Create a new connection or edit an existing stored connection and check the Infer Relationships checkbox to activate this feature.
