SQL Server 中“CREATE TABLE table AS”中的“分发选项”错误

Question

我在使用 CREATE TABLE AS 时遇到了问题。我在数据库中创建了三个表。我打算根据策略编号加入表，并根据加入的数据创建一个新表。

CREATE TABLE [dbo].[New_Customer_Segmentation_Data] AS 
( 
SELECT *
FROM [dbo].[CustomerSegmentation_updated]
INNER JOIN [dbo].[DimLapse]
ON [dbo].[CustomerSegmentation_updated].[PolicyNumber] = [dbo].[DimLapse].[Policy Number] 
INNER JOIN [dbo].[dimclaim]
ON [dbo].[DimLapse].[Policy Number]  = [dbo].[dimclaim].[POLICYNUMBER]
)

它返回错误“'Distribution' 选项必须在“CREATE TABLE AS SELECT”和“CREATE MATERIALIZED VIEW”语句中明确指定。” 谁能指导我解决这个错误？

正如错误消息所说，您必须使用 CTAS 指定 Distributed table design 选项，例如来自文档：

CREATE TABLE [dbo].[FactInternetSales_new]
WITH
(
 DISTRIBUTION = ROUND_ROBIN
 ,CLUSTERED COLUMNSTORE INDEX
)
AS
SELECT  *
FROM    [dbo].[FactInternetSales];

CREATE TABLE AS SELECT
