Invoke-Sqlcmd not working in SQL

问题

Im using the following command in SQL Powershell to generate csv of data returned by SQL.

Invoke-Sqlcmd -Query "myp" -ServerInstance "." | Export-Csv -Path "d:\data\MyDatabaseSizes.csv" -NoTypeInformation

The above command works perfectly fine in SQL Power Shell. but when I tried to run in from SQL using the following code

DECLARE @cmd varchar(1000)
SET @cmd = 'Invoke-Sqlcmd -Query "myp" -ServerInstance "." | Export-Csv -Path "d:\data\MyDatabaseSizes.csv" -NoTypeInformation'
EXEC xp_cmdshell @cmd

it give error that

'Invoke-Sqlcmd' is not recognized as an internal or external command,

Anyone please help me in running the command from SQL.

Thanks

xp_cmdmshell executes Windows shell commands, not PowerShell commands. You can of course call PowerShell from within the Windows shell, for example like this:

DECLARE @cmd varchar(1000)
SET @cmd = 'Invoke-Sqlcmd -Query ''myp'' -ServerInstance ''.'' ^| Export-Csv -Path ''d:\data\MyDatabaseSizes.csv'' -NoTypeInformation'
EXEC xp_cmdshell 'powershell.exe -c "' + @cmd + '"'

Note that:

I have replaced the double quotes in the PowerShell command with single quotes (escaped for SQL) so I can use double quotes in the Windows command. If you need double quotes in the PowerShell, you're better off having the PowerShell script in a file to avoid all this
You may also need more parameters (e.g. to set the execution policy). This MSDN page has more help on PowerShell command line switches
Pipe characters in command line arguments need to be escaped with ^
