Connect to SQL Server Database from PowerShell

问题

I have looked around online for a while now and found many similar problems but for some reason I can't seem to get this working.

I am just trying to connect to a SQL server database and output the query results to a file - See PowerShell script below. What I am uncertain about is how to integrate the User ID and Password into the connection string.

$SQLServer = "aaaa.database.windows.net"
$SQLDBName = "Database"
$uid ="john"
$pwd = "pwd123"
$SqlQuery = "SELECT * from table;"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True; User ID = $uid; Password = $pwd;"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)

$DataSet.Tables[0] | out-file "C:\Scripts\xxxx.csv"

The following error message is received:

Exception calling "Fill" with "1" argument(s): "Windows logins are not supported in this version of SQL Server."

回答1:

Change Integrated security to false in the connection string.

You can check/verify this by opening up the SQL management studio with the username/password you have and see if you can connect/open the database from there. NOTE! Could be a firewall issue as well.

回答2:

Integrated Security and User ID \ Password authentication are mutually exclusive. To connect to SQL Server as the user running the code, remove User ID and Password from your connection string:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;"

To connect with specific credentials, remove Integrated Security:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; User ID = $uid; Password = $pwd;"

# database Intraction

$SQLServer = "YourServerName" #use Server\Instance for named SQL instances!
$SQLDBName = "YourDBName"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; 
User ID= YourUserID; Password= YourPassword" 
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = 'StoredProcName'
$SqlCmd.Connection = $SqlConnection 
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd 
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet) 
$SqlConnection.Close() 

#End :database Intraction
clear

回答4:

Assuming you can use integrated security, you can remove the user id and pass:

$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;"

回答5:

The answer are as below for Window authentication

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"
