sql-server - 意外 token 'UpdateOptions.ExpandFull'

Question

基于https://learn.microsoft.com/en-us/bi-reference/tom/add-a-data-source-to-tabular-model-analysis-services-amo-tom

我正在尝试更新数据库连接字符串更改:

Import-Module SqlServer

$newConnectionString = "Connection Timeout=60;User Id=SOME_NEW_ID;Data Source=10.10.19.10;Persist Security Info=True;Session Character Set=UTF8"

 $svr = new-Object Microsoft.AnalysisServices.Tabular.Server
$svr.Connect("server1.domain.com")

$svr.databases[1].model.datasources[0].ConnectionString = $newConnectionString
$svr.Databases[1].model.datasources[0].Update(UpdateOptions.ExpandFull)

但我收到错误:

Unexpected token 'UpdateOptions.ExpandFull' in expression or statement.

如果我定期更新():

$svr.Databases[1].model.datasources[0].Update()

我明白了:

Method invocation failed because [Microsoft.AnalysisServices.Tabular.ProviderDataSource] does not contain a method named 'Update'

如果我尝试SaveChanges():

$svr.Databases[1].Model.SaveChanges()

我收到此错误:

The following exception occurred while retrieving member "SaveChanges": "Encountered an invalid type for a default value."

如果我尝试ExpandFull

$svr.Databases[1].model.datasources[0].Update(ExpandFull)

我明白了

Unexpected token 'ExpandFull' in expression or statement.

Answer 1

错误是您指定更新枚举的方式。

您直接使用 .NET 类型，并且必须了解/知道给定枚举所属的位置。在本例中，UpdateOptions 位于 Microsoft.AnalysisServices 命名空间中

已更新

Import-Module SqlServer

$newConnectionString = "Connection Timeout=60;User Id=SOME_NEW_ID;Data Source=10.10.19.10;Persist Security Info=True;Session Character Set=UTF8"

$svr = new-Object Microsoft.AnalysisServices.Tabular.Server
$svr.Connect("server1.domain.com")

$svr.databases[1].model.datasources[0].ConnectionString = $newConnectionString
$svr.Databases[1].Update([Microsoft.AnalysisServices.UpdateOptions]::ExpandFull)
