參數

• input
  型別：System.Data.SqlTypes.SqlString
  String representation of SqlHierarchyId node.

傳回值

型別：Microsoft.SqlServer.Types.SqlHierarchyId
SqlHierarchyId representing the node described canonically.

備註

Called implicitly when a conversion from a string type to SqlHierarchyId data type occurs.

Acts as the opposite of ToString.

An exception is raised if Parsereceives a value that is not a valid string representation of a SqlHierarchyId.

This member is static.

範例

DECLARE @StringValue AS nvarchar(4000), @hierarchyidValue AS hierarchyid
SET @StringValue = '/1/1/3/'
SET @hierarchyidValue = 0x5ADE

SELECT hierarchyid::Parse(@StringValue) AS hierarchyidRepresentation,
 @hierarchyidValue.ToString() AS StringRepresentation ;
GO
