dax 两列有 isKey=true

Question

我在 Microsoft 表格模型中创建日期 table。

来源 code 是：

{
    "name": "Дата",
    "dataCategory": "Time",
    "columns": [
      {
        "name": "DateID",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "DateID",
        "sourceProviderType": "Integer"
      },
      {
        "name": "FullDateAlternateKey",
        "dataType": "dateTime",
        "isHidden": true,
        "isKey": true,
        "sourceColumn": "FullDateAlternateKey",
        "formatString": "General Date",
        "sourceProviderType": "DBDate"
      },
      {
        "name": "DayNumberOfWeek",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "DayNumberOfWeek",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "DayNameOfWeek",
        "dataType": "string",
        "isHidden": true,
        "sourceColumn": "DayNameOfWeek",
        "sourceProviderType": "WChar"
      },
      {
        "name": "DayNumberOfMonth",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "DayNumberOfMonth",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "DayNumberOfYear",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "DayNumberOfYear",
        "sourceProviderType": "SmallInt"
      },
      {
        "name": "Неделя",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "WeekNumberOfYear",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "Месяц",
        "dataType": "string",
        "isHidden": true,
        "sourceColumn": "MonthName",
        "sourceProviderType": "WChar"
      },
      {
        "name": "MonthNumberOfYear",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "MonthNumberOfYear",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "Квартал",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "CalendarQuarter",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "Год",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "CalendarYear",
        "sourceProviderType": "SmallInt"
      },
      {
        "name": "Полугодие",
        "dataType": "int64",
        "isHidden": true,
        "sourceColumn": "CalendarSemester",
        "sourceProviderType": "UnsignedTinyInt"
      },
      {
        "name": "IsWeekend",
        "dataType": "boolean",
        "isHidden": true,
        "sourceColumn": "IsWeekend",
        "formatString": "\"TRUE\";\"TRUE\";\"FALSE\"",
        "sourceProviderType": "Boolean"
      }
    ],
    "partitions": [
      {
        "name": "Дата",
        "source": {
          "query": "SELECT [dbo].[DimDate].* FROM [dbo].[DimDate]",
          "dataSource": "SqlServer MS-SQL2MSSQLTEST GoodWillDW"
        },
        "annotations": [
          {
            "name": "QueryEditorSerialization",
            "value": "<?xml version=\"1.0\" encoding=\"UTF-16\"?><Gemini xmlns=\"QueryEditorSerialization\"><AnnotationContent><![CDATA[<RSQueryCommandText>SELECT [dbo].[DimDate].* FROM [dbo].[DimDate]</RSQueryCommandText><RSQueryCommandType>Text</RSQueryCommandType><RSQueryDesignState></RSQueryDesignState>]]></AnnotationContent></Gemini>"
          }
        ]
      }
    ]
}

尝试在服务器上部署解决方案并出现错误无法部署metadata。

Reason: Failed to save modifications to the server. Error returned: 'The table 'Дата' has two columns with the IsKey property set to True.

但在代码中似乎有一个 isKey 属性！！！！！！这个表格模型是怎么回事？？？它在哪里找到两列？？？？

Answer 1

所有 table 都有一个固有的特殊 "RowNumber" 列，默认情况下其 IsKey 属性设置为 true。有时，根据您部署更改的方式，这将与在 table.

的另一列上将 IsKey 设置为 true 发生冲突。

通常，在 createOrReplace TMSL 操作中编写 table 脚本可以解决问题：

{   
  "createOrReplace": {
    "object": {
      "database": "MyDatabase",
      "table": "Дата"
    }, 
    "table": {
      "name": "Дата",
      "dataCategory": "Time",
      "columns": [
        ...
        {
          "name": "FullDateAlternateKey",
          "dataType": "dateTime",
          "isHidden": true,
          "isKey": true,
          "sourceColumn": "FullDateAlternateKey",
          "formatString": "General Date",
          "sourceProviderType": "DBDate"
        }
        ...
      ]
    }
  }
}

如果还是不行，先尝试删除table。

dax 两列有 isKey=true

dax two columns has isKey=true
