在PowerShell中存儲並重新使用sql連接字符串

有沒有一種方法可以保存sql連接的詳細信息並在同一個腳本中重新使用它們。我寫了下面的內容，將3個sql表的內容導出到同一個數據庫中。它的工作原理，但它重新使用一個代碼的負載，我不知道如何減少它。在PowerShell中存儲並重新使用sql連接字符串

我試過聲明所有的連接信息，然後說明它現在的完整代碼的位置，但只輸出第一個表3次。

我也試過說過一次在開始時再次沒有工作。

#agent_lookup 

$server = "test" 
$database = "MI_Lookups" 
$query = "EXEC [dbo].[proc_update_new_agents] 
      SELECT [l].agent_key AS 'Agent_Key' 
        ,ISNULL([l].agent_name,'') AS 'Agent_Name' 
        ,ISNULL([l].agent_name_1,'') AS 'Agent_Name_1' 
        ,ISNULL([l].agent_type,'') AS 'Agent_Type' 
      FROM [dbo].[agent_test] AS [l] 
      ORDER by [l].agent_key asc" 

$connection = New-Object System.Data.SqlClient.SqlConnection("Data Source=$server;Integrated Security=SSPI;Initial Catalog=$database;") 
$command = New-Object System.Data.SqlClient.SqlCommand($query, $connection) 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter($command) 
$DataSet = New-Object System.Data.DataSet 

$SqlAdapter.Fill($DataSet) 
$DataSet.Tables[0] | Export-Csv $saveloaction\"Agent_Lookup.csv" 
$connection.Close() 

#organisation_lookup 

$server = "test" 
$database = "MI_Lookups" 
$query = "EXEC [dbo].[proc_update_new_organisations] 
      SELECT [l].organisation_key AS 'Organisation_Key' 
        ,ISNULL([l].broker_name,'') AS 'Broker_Name' 
        ,ISNULL([l].team_member,'') AS 'Team_Member' 
        ,ISNULL([l].team_leader,'') AS 'Team_Leader'

      ORDER BY [l].organisation_key asc" 

$connection = New-Object System.Data.SqlClient.SqlConnection("Data Source=$server;Integrated Security=SSPI;Initial Catalog=$database;") 
$command = New-Object System.Data.SqlClient.SqlCommand($query, $connection) 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter($command) 
$DataSet = New-Object System.Data.DataSet 

$SqlAdapter.Fill($DataSet) 
$DataSet.Tables[0] | Export-Csv $saveloaction\"Organisation_Lookup.csv" 
$connection.Close() 

#insurer_lookup 

$server = "test" 
$database = "MI_Lookups" 
$query = "EXEC [dbo].[proc_update_new_insurers] 
      SELECT [l].insurer_key AS 'Insurer_Key' 
        ,ISNULL([l].insurer_name,'') AS 'Insurer_Name' 
        ,ISNULL([l].insurer_name_1,'') AS 'Insurer_Name_1' 
        ,ISNULL([l].team_member,'') AS 'Team_Member' 
        ,ISNULL([l].team_leader,'') AS 'Team_Leader' 
      FROM [dbo].[insurer_test] AS [l] 
      ORDER BY [l].insurer_key asc" 

$connection = New-Object System.Data.SqlClient.SqlConnection("Data Source=$server;Integrated Security=SSPI;Initial Catalog=$database;") 
$command = New-Object System.Data.SqlClient.SqlCommand($query, $connection) 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter($command) 
$DataSet = New-Object System.Data.DataSet 

$SqlAdapter.Fill($DataSet) 
$DataSet.Tables[0] | Export-Csv $saveloaction\"Insurer_Lookup.csv" 
$connection.Close()

這似乎是合乎邏輯的我只需要編寫一次的連接信息，但我是新來的PowerShell和努力，使這個簡單，我敢肯定，也是應該的。以上是基本相同的腳本重複三次與不同的表引用。

一如既往的感謝。

我會用一個函數來處理查詢的執行。這樣你只需要改變查詢和存儲輸出的地方。

請注意，我已將數據庫詳細信息作爲全局變量。如果您只使用這一個腳本，這很好，但如果此腳本正在調用或被其他腳本調用，則最好避免。

function Query-ToCsv($query, $csvLocation) { 

    try { 
     $command = New-Object System.Data.SqlClient.SqlCommand($query, $connection) 
     $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter($command) 
     $DataSet = New-Object System.Data.DataSet 
     $SqlAdapter.Fill($DataSet) 
     $DataSet.Tables[0] | Export-Csv $csvLocation 
    } 
    catch { 
     Write-Warning "Exception: " + $_.Exception.Message 
    } 
}

請注意，這是未經測試（顯然，因爲我沒有訪問到你的數據庫），但應該讓你在正確的方向前進。

天才！我能夠完美地實現這一點。我甚至設法在腳本的另一個元素中重新使用try/catch，並將結果附加到日誌文件中。謝謝。 – chris1982 2015-03-04 09:11:22

您可以簡單地重新使用連接對象。我已經編輯了你的代碼來做到這一點，但我沒有運行它 - 對不起，如果我做了一些不好的編輯，但它的主旨應該是正確的。
