Question

如何读取带有长字符串的.sql文件，如下所示，并执行下面演示的powershell命令。问题是它需要一行＆＃34;

  $Q = Get-Content C:\Charms\t-sql\AdUserCreation.sql   
    $CH=Get-SqlServerData -SqlServerInstanceName "server" -DbName "mydatabase" -SqlQuery $Q

$ SqlQuery类

该文件看起来像这样

SELECT  DISTINCT
p.PersonId AS EmployeeIdentification,
Si.SiteInitials,            
LOWER((LEFT(p.FirstName,1) + p.SurName)) AS UserName,
p.FirstName,
p.SurName As Lastname,
p.SurName + ', ' + p.FirstName + ' (MSH)@DSH' AS DisplayName,
A.[Address1],
A.City,
'CA' AS CA,
A.PostalCode As ZipCode,
'%ProfilesFolder%\%USERNAME%\' AS ProfilePath, 
'DSH' AS Department,
LOWER((LEFT(p.FirstName,1) + p.SurName)) AS SamAccountName,
 (CASE WHEN charindex('-', rtrim(ltrim(p.SurName))) > 0 THEN LOWER(LEFT(rtrim(ltrim(p.FirstName)), 
                         1)) + LOWER(SUBSTRING(p.SurName, CHARINDEX('-', p.SurName) + 1, LEN(p.SurName))) + '@dsh.ca.gov' WHEN charindex(' ', rtrim(ltrim(p.SurName))) 
                         > 0 THEN LOWER(LEFT(ltrim(rtrim(p.FirstName)), 1)) + LOWER(SUBSTRING(p.SurName, CHARINDEX(' ', p.Surname) + 1, LEN(p.SurName))) 
                         + '@dsh.ca.gov' ELSE LOWER(LEFT(ltrim(rtrim(p.FirstName)), 1) + rtrim(ltrim(p.SurName))) + '@dsh.ca.gov' END) AS UserPrincipalName,
class.ClassificationNumber AS ClassCode,
class.ClassificationTitle  AS JobTitle,
p.PersonId AS EmployeeIdentification,
'Created Date : ' + CAST(GETDATE() AS varchar(100)) AS MyDescription

FROM                    dbo.Person AS p INNER JOIN
                         dbo.Staff AS s ON p.PersonId = s.PersonId INNER JOIN
                         dbo.Employee AS e ON s.StaffId = e.StaffId INNER JOIN
                         dbo.EmployeePosition AS ep ON e.EmployeeId = ep.EmployeeId 


ect...

Answer 1

这是一个文件（c:\temp\abc.txt）

AA
BB
CC

使用简单Get-Content给出

PS C:\Temp> $a = Get-Content C:\temp\abc.txt
PS C:\Temp> $a.GetType()
IsPublic IsSerial Name                                     BaseType                                                                                                       
-------- -------- ----                                     --------                                                                                                       
True     True     Object[]                                 System.Array

所以你可以试试这个：

PS C:\Temp> $a = Get-Content C:\temp\abc.txt -Raw
PS C:\Temp> $a.GetType()
IsPublic IsSerial Name                                     BaseType                                                                                                       
-------- -------- ----                                     --------                                                                                                       
True     True     String                                   System.Object

或者

PS C:\Temp> $a = Get-Content C:\temp\abc.txt | out-string
PS C:\Temp> $a.GetType()
IsPublic IsSerial Name                                     BaseType                                                                                                       
-------- -------- ----                                     --------                                                                                                       
True     True     String                                   System.Object

Answer 2

所有建议都未能运行。我是这样做的

$query = @"

SELECT TOP 1 * 
FROM PERSON

"@



 Function Get-SqlServerData
 {
  #required paramaters
  param(
        [string]  $SqlServerInstanceName,
        [string]  $DbName,
        [string]  $SqlQuery
        )
        $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
        $SqlCmd        = New-Object System.Data.SqlClient.SqlCommand
        $SqlAdapter    = New-Object System.Data.SqlClient.SqlDataAdapter
        $DataSet       = New-Object System.Data.DataSet

        $SqlConnection.ConnectionString ="Server = $SqlServerInstanceName ; Database = $DbName; Integrated Security = True"
        $SqlCmd.CommandText = $SqlQuery
        $SqlCmd.Connection = $SqlConnection
        $SqlAdapter.SelectCommand = $SqlCmd
        $SqlAdapter.Fill($DataSet)
        $SqlConnection.Close();
        Return $DataSet.Tables[0]  
 }


$data=Get-SqlServerData -SqlServerInstanceName "myseever" -DbName "mydatabasename" -SqlQuery $query

powershell需要执行的非常长的查询

该文件看起来像这样
