This dialog box allows you to create and edit properties.
To call Property Editor, use one of the following options:
| • | In the Model Explorer window or in the diagram right-click the required class or complex type to call its context menu, and in the Add submenu select New Property. |
| • | In the Model Explorer window or in the diagram select the required class or complex type and press ALT+P. |
| • | In the Model Explorer window or in the diagram right-click an existing property and in its context menu select Edit. |
The following options are available:
Name - set the property name here.
Type - set the property type. Acceptable values are: Binary, Boolean, Byte, DateTime, DateTimeOffset, Decimal, Double, Guid, Int16, Int32, Int64, SByte, Single, String, Time.
Nullable - select to make the property nullable.
Entity Key - select to include the property to entity key. Not available for complex type properties.
Concurrency check - select to enable concurrency check for the property. The auto-generated SQL statement compares the original value that was queried from the database to the current value in the data store. If there are any conflicts, an exception is thrown.
Store Generated - determines if the column needs a value during insert and update operations, or it is autogenerated. Can accept the following values:
None - It is not a server generated property. This is the default value.
Identity - a value is generated on insert and remains unchanged on update.
