Question

您好，我正在尝试整理一个脚本，以在表格数据模型中创建多个分区。我一次可以做一个，但是以下消息似乎是错误的倍数。无法识别的JSON属性：分区。检查路径“ create.partitions”

我正在使用以下（匿名）生成的脚本。

{
    "create": {
        "parentObject": {
            "database": "MY_TABULAR",
            "table": "MY_TABLE"
        },
        "partitions": [{
            "name": "MY_TABLE 12 2018-09",
            "source": {
                "query": "SELECT * FROM [Fact].[MY_TABLE] WHERE PlanKey = 12 AND dateKey BETWEEN 20180901 AND 20180930",
                "dataSource": "MY_DW"
            }
        },
        {
            "name": "MY_TABLE 12 2018-10",
            "source": {
                "query": "SELECT * FROM [Fact].[MY_TABLE] WHERE PlanKey = 12 AND dateKey BETWEEN 20181001 AND 20181031",
                "dataSource": "MY_DW"
            }
        },
        {
            "name": "MY_TABLE 12 2018-11",
            "source": {
                "query": "SELECT * FROM [Fact].[MY_TABLE] WHERE PlanKey = 12 AND dateKey BETWEEN 20181101 AND 20181130",
                "dataSource": "MY_DW"
            }
        }]
    }
}

据我从参考文献中可以看出，这是正确的，但SSMS似乎并不喜欢它。

您可以通过使用<system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="http://localhost:4200" /> <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS,PUT,DELETE,PATCH" /> <add name="Access-Control-Allow-Headers" value="Content-Type, X-Requested-With" /> <add name="Access-Control-Allow-Credentials" value="true" /> </customHeader></httpProtocol></system.webServer>命令执行多个将创建分区的Sequence命令来执行此操作。 CreateOrReplace命令的确具有可选的Sequence属性，但是只有刷新操作并行运行（每个MSDN）。下面的示例对此进行了详细说明。
