Public NotInheritable Class UserDefinedType
    Inherits ScriptSchemaObjectBase
    Implements IObjectPermission, ICreatable, IDroppable, IExtendedProperties, _
    IScriptable

[EvaluationModeAttribute(AutomatedPolicyEvaluationMode.CheckOnSchedule)] 
[PhysicalFacetAttribute] 
public sealed class UserDefinedType : ScriptSchemaObjectBase, IObjectPermission, ICreatable, IDroppable, 
    IExtendedProperties, IScriptable

[EvaluationModeAttribute(AutomatedPolicyEvaluationMode::CheckOnSchedule)] 
[PhysicalFacetAttribute] 
public ref class UserDefinedType sealed : public ScriptSchemaObjectBase, IObjectPermission, ICreatable, IDroppable, 
    IExtendedProperties, IScriptable

/** @attribute EvaluationModeAttribute(AutomatedPolicyEvaluationMode.CheckOnSchedule) */ 
/** @attribute PhysicalFacetAttribute() */ 
public final class UserDefinedType extends ScriptSchemaObjectBase implements IObjectPermission, ICreatable, 
    IDroppable, IExtendedProperties, IScriptable

Remarks

To get UserDefinedType object permissions, users can be a member of the public fixed server role.

To set UserDefinedType object permissions, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.

To create a alias data type, users must have CREATE TYPE permission in the parent database and ALTER permission on specified schema. If an assembly is specified, users must either own the assembly or have REFERENCES permission on it.

To drop a alias data type, users must have CONTROL permission on the type and ALTER permission on the specified schema.

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
