Fore.NET Syntax

DataDomain: Prognoz.Platform.Interop.Dal.DbDataDomain;

Description

The DataDomain property determines data type used to store multibyte information in attribute.

Comments

If the DataDomain property is set to DbDataDomain.Memo and the IRdsAttribute.DataType property is set to DbDataType.String, the attribute has the Long Text type.

Consider the following constraints on working with the Long Text attribute:

If Oracle or Teradata DBMS is used, it is not available to search by this attribute value.
Attributes of this type are supported only for table MDM dictionaries and composite table MDM dictionaries.
These attributes cannot be included into a unique and nonunique indexes.
These attributes may be sampled and saved slower than standard text attributes.

DataDomain can be set to DbDataDomain.Memo or to DbDataDomain.None for table MDM dictionaries or for composite table MDM dictionaries.
