问题: 当我使用部署向导部署表格模型时。工作正常。但是我们的问题是我们有20个数据源,并且在部署时,我们需要提供20次凭据,因为它要求每个数据源都提供凭据。这是非常痛苦的。这就是为什么我们要自动化部署。
方法: 我遵循了本文https://notesfromthelifeboat.com/post/analysis-services-1-deployment/,并且当我刷新模型时,能够无错误地部署表格模型。失败并显示以下错误
无法将修改保存到服务器。返回错误:'OLE DB或ODBC错误:
The credentials provided for the File source are invalid. (Source at \\share\acaidatatempshare\data\lumeneventpropertiesexport.tsv.).
OLE DB or ODBC error: The command has been canceled..
OLE DB or ODBC error: The command has been canceled..
OLE DB or ODBC error: The command has been canceled..
我的数据源是tsv文件,下面是model.bim文件的数据源部分。如您所见,它没有将凭据的密码保存在model.bim,asdatabase或xmla文件中。

如何在部署过程中以编程方式传递数据源的凭据?
答案 0 :(得分:1)
不幸的是,在部署模型时,结构化(也称为Power Query)数据源凭据不会保留。我前一段时间在产品团队中报告这是一个错误,但尚未得到答复。如果可以的话,请考虑改用旧版(即提供程序)数据源,因为这些数据源可保留部署之间的凭据。
或者,您可以使用TMSL "createOrReplace" script以编程方式应用密码。创建脚本等最简单的方法是,连接到SSMS中的Analysis Services,右键单击连接(也就是数据源),然后选择“脚本连接为”>“创建或替换为”>“新建查询编辑器”窗口”。在生成的脚本中,确保正确设置了密码:
{
"createOrReplace": {
"object": {
"database": [...] ,
"dataSource": "File/\\\\Share\\AcaiDataTempShare\\Data\\LumenEventPropertiesExport tsv"
},
"dataSource": {
[...]
"credential": {
"AuthenticationKind": "Windows",
"kind": "File",
"path": "\\\\Share\\acaidatatempshare\\data\\lumeneventpropertiesexport.tsv",
"Username": "domain\\username",
"Password": "<<< YOUR PASSWORD HERE >>>"
},
[...]
}
然后,您可以在部署管道中调用此脚本,例如使用PowerShell Invoke-AsCmd cmdlet。

这是我最终创建的最终脚本。
