根据类型编号获取父类名称
-- =============================================
CREATE FUNCTION [dbo].[FN_getParentTypeNameByTypeID]
(
@TypeID INT
)
RETURNS NVARCHAR(100)
AS
BEGIN
DECLARE @parentTypename NVARCHAR(100)
SELECT @parentTypename=TypeName FROM BioProType
WHERE TypeID=(SELECT ParentTypeID FROM dbo.BioProType WHERE
TypeID=@TypeID)
RETURN @parentTypename
END
1.管理页面实现产品类型列表显示（分页）。
