Pass SQl Query parameter for Powershell Script

Hi,

I have following parameters being passed from SQL Stored procedure to Powershell.

----------PowerShell Start

 param

(

      [string] $server = "SQL2",

     [string] $database  = ("Utils"),

    [string] $query ="Select * from xPM_Extract",

    [string] $extractFile = "C:\temp\csv2  export.csv"

)

Write-Host $server

Write-Host $database

Write-Host $query

Write-Host $extractFile

----------PowerShell END

Problem is that parameters for $query & $extractFile are cutoff at first encounter of space. I call my SP as

Exec usp_MYPS_Export2CSV 'Utils','Select * From Customers','C:\temp\csv2 out.csv'

Translates to

EXEC xp_cmdshell 'PowerShell -Command"C:\Util\PSScripts\SQL_Export2CSV2.ps1 -Server SQL3 -database Test -query Select * From Customers -extractFile "C:\temp\csv2  out.csv"'

Output from Powersehll is Shown below after executing above statement from SSMS.

SQL3

Test

Select

C:\temp\csv2

------------output Ends here

I want to see output as below.

SQL3

Test

Select * from xPM_Extract

C:\temp\csv2  export.csv

 Please notice that Query is trimmed at Select and Output file name is trimmed at csv2.

 How to pass parameters with space in them?

Thanks.
