GuidMetadata

Metadata for a Dataverse unique identifier (GUID) column.

GuidMetadata Class

Properties

Name
Type
Default
Description
ColumnNamestring
The logical name of the column in Dataverse (e.g. 'firstname', 'emailaddress1').
ColumnTypeColumnType
Uniqueidentifier
Returns Uniqueidentifier.
DerivedFromColumnstring?
The logical name of the column this one takes its value from, or null when the column stands on its own. Dataverse creates companion columns that republish another column's value under a second name: the …name / …yominame partners of a lookup, the label partner of a choice, and the base-currency twin of every money column, which carries the same amount converted to the organization's base currency. The platform reports the link on two different properties — AttributeOf for the companions, CalculationOf for the base-currency twin — and this is both of them, resolved to one. Column security reads it: withholding a column has to withhold whatever republishes it, or denying creditlimit still ships creditlimit_base with the real amount in it. See TableMetadata.ResolveValueSourceColumn, which follows the chain to its root.
Descriptionstring?
The localized description of the column, or null if no description is configured.
DisplayNamestring
The localized display name of the column as configured in Dataverse.
IsValidForCreatebool
False
Indicates whether this column can be set when creating a new record.
IsValidForUpdatebool
False
Indicates whether this column can be modified when updating an existing record.
RequiredLevelRequiredLevel
None
The required level of the column (None, SystemRequired, ApplicationRequired, or Recommended).
SourceTypeColumnSourceType
Simple
Whether the column is stored as it was written, or computed by the platform from other columns. See Models.ColumnSourceType — a computed column does not report which columns feed it, so ColumnMetadataBase.DerivedFromColumn is null for one even though its value may well be derived.
