1.本地电脑的powershell安装所需的模块：

安装的时候网速会很慢，可以下载v2安装提高模块的安装速度，压缩包有视频教程
链接：百度云
=========================================================
模块的安装步骤：
1.管理员运行powershell

2.命令：Set-ExecutionPolicy
（这是修改powershell的执行策略）
ExecutionPolicy: Unrestricted

3. Get-ExecutionPolicy -list
   查看修改后的执行策略

4.根据以下的链接教程开始安装，安装模块如果提示不受信任的库 填写 Y继续

Install-Module -Name Az.AnalysisServices
安装Azure AnalysisServices 的模块

Install-Module -Name SqlServer -AllowClobber
注意：安装sqlserver模块后，
出现问题可以去C:\Program Files\WindowsPowerShell\Modules删除SqlServer文件夹，
再一次执行安装以下命令

Install-Module -Name SqlServer -AllowClobber

5.Get-Module SqlServer -ListAvailable
查看sqlserver模块的版本

6. Import-Module SqlServer
   导入模块不报错就代表成功一半

7.Invoke-ProcessASDatabase -Server "as地址"
不报错就ok了

8.测试 Invoke-ASCmd -Server:as地址 -Query:xmla脚本

=========================================================

2.相关命令语法链接：

Invoke-ProcessASDatabase

Invoke-ProcessASDatabase -Server "l\l2019"  -DatabaseName "test-1"  -RefreshType "Full"

Invoke-ASCmd命令

刷新分区：

$query1 = '{
    "refresh": {
      "type": "full",
      "objects": [
        {
          "database": "test_part",
          "table": "part_tabel",
          "partition": "Partition1"
        }
      ]
    }
  }'
  $query_all = '{
    "refresh": {
      "type": "full",
      "objects": [
        {
          "database": "test_part",
          "table": "part_tabel",
          "partition": "Partition1"
        },
        {
          "database": "test_part",
          "table": "part_tabel",
          "partition": "Partition2"
        }
      ]
    }
  }'
  $ETL_date_day =(get-date).adddays(-2)| get-date -format "dd"

$query=if ($ETL_date_day -eq "01") {$query_all} else {$query1}
Invoke-ASCmd -Server:l\l2019 -Query:$query
  

创建分区：

创建分区的xmls的语句可以从ssms获得

注意：单引号的拼接以及双引号的转义

原句：[Query="select * from [dbo].[part_1] where date>=' " &x2&" ' "]

$query='{
  "createOrReplace": {
    "object": {
      "database": "test_part",
      "table": "part_tabel",
      "partition": "Partition8"
    },
    "partition": {
      "name": "Partition8",
      "source": {
        "type": "m",
        "expression": [
          "let",
          "    x1=Date.AddMonths(Date.AddDays(DateTime.LocalNow(), -2),-3),//etl date",
          "    x2=Date.ToText(#date(Date.Year(x1),Date.Month(x1),1)),   //4 month ago",
          "",
          "    all = Sql.Database(\"l\\l2019\", ",
          "            \"test\",",
          "             [Query=\"select  * from [dbo].[part_1] where date>='+"'"+'\"&x2&\"'+"'"+'\"])",
          "    ",
          "in",
          "    all"
        ]
      },
      "annotations": [
        {
          "name": "QueryEditorSerialization",
          "value": [
            "<?xml version=\"1.0\" encoding=\"UTF-16\"?><Gemini xmlns=\"QueryEditorSerialization\"><AnnotationContent><![CDATA[<RSQueryCommandText>let",
            "    x1=Date.AddMonths(Date.AddDays(DateTime.LocalNow(), -2),-3),//etl date",
            "    x2=Date.ToText(#date(Date.Year(x1),Date.Month(x1),1)),   //4 month ago",
            "",
            "    all = Sql.Database(\"l\\l2019\", ",
            "            \"test\",",
            "             [Query=\"select  * from [dbo].[part_1] where date>='+"'"+'\"&x2&\"'+"'"+'\"])",
            "    ",
            "in",
            "    all</RSQueryCommandText><RSQueryCommandType>Text</RSQueryCommandType><RSQueryDesignState></RSQueryDesignState>]]></AnnotationContent></Gemini>"
          ]
        }
      ]
    }
  }
}
'
  Invoke-ASCmd -Server:l\l2019 -Query:$query

#annotations这段不能去掉，避免其他错误

Invoke-Sqlcmd

Invoke-Sqlcmd创建视图

$query="create view [dbo].[1_test_fact_201912] as select * from [dbo].[fact_201912]"
Invoke-Sqlcmd -Query $query -ServerInstance "云端或本地数据库的地址" -Database "test_databse" -Username "admin" -Password "mypassword"

在vscode运行powershell脚本，而脚本里面有中文，需要当前脚本的编码与电脑的powershell的编码一致，否则vscode无法运行此脚本。
右击powershell的顶部，查看编码

查看vscode的编码
