I have :CREATE TABLE [dbo].[Fact]( [Id_Fact] [int] IDENTITY(1,1) NOT NULL, [Id_Elem] [int] NULL, [Id_Store] [int] NULL, CONSTRAINT [PK_H_Movimientos] PRIMARY KEY CLUSTERED ( [Id_Mov] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOCREATE TABLE [dbo].[Dim_Store]( [Id_Store] [int] IDENTITY(1,1) NOT NULL, [Name] [varchar](50) NULL, CONSTRAINT [PK_Dim_Store] PRIMARY KEY CLUSTERED ( [Id_Store] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOCREATE TABLE [dbo].[Dim_Elem]( [Id_Elem] [int] IDENTITY(1,1) NOT NULL, [Name] [varchar](50) NULL, CONSTRAINT [PK_Dim_Elem] PRIMARY KEY CLUSTERED ( [Id_Elem] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOA Fact table an two dimensions, the data in dimensions is:INSERT INTO [dbo].[Dim_Elem] ([Name]) VALUES ('Elem 1'), ('Elem 2'), ('Elem 3')GoINSERT INTO [dbo].[Dim_Store] ([Name]) VALUES ('AI'), ('AII'), ('AIII')Goinsert into [dbo].[Fact]([Id_Elem], [Id_Store]) values (1, 2),(2, 1),(1, NULL),(3, 2),(3, 3)how to make this SQL Query:select a.Id_Store, count(distinct a.Id_Elem)from Fact a inner join (select Id_Elem, max(Id_Fact) as Id_Fact from Factgroup by Id_Elem) x on a.Id_Elem = x.Id_Elem and a.Id_Fact = x.Id_Fact and a.Id_Store is not nullgroup by a.Id_Storein MDX QueryThanks
