- Name
-
Schema
- Attributes list
- Comment
- Permission
- Foreign Server combobox

Attribute
The Collation combobox is available for:
- Data Type— Text, Character varying(x), Character(x), Varchar
-
User Data Type— Base type with selected Collatable checkbox
-
Dictionary Type—if correct Data Type or User Data Type is selected (see above)

- CREATE/DROP/ALTER are not supported

User Data Type—Composite Type
COLLATE collation definition can be used for every attribute to set its Collation. To set Collation, manually write COLLATE collation expression in Composite Type tab right after "attributename datatypename" definition (see the screenshot above). Toad Data Modeler will load it during RE.
No attribute is necessary for Composite Type.
Index
It is possible to set Collation of every column/attribute of the table.
To set Collation
- Select the Generate Expression checkbox.
- In the Expression box, write e.g "atr1 COLLATE collname DESC, atr2".
Toad Data Modeler loads this index as an expression during RE.
Relationship
Not Valid checkbox—option when you add a constraint of a foreign key.
