I am creating a LIST in SharePoint using PowerShell via a CSV file. I am able to create the list as well as add items successfully, although I need to validate that the item (row) that I add to the list does not already exist in the list, prior to updating the list.
In the code I am not able to get $ItemExist correctly. It always returns a Null value. ($MaxItems currently has a value of 2 as there are 2 items in the list "list_DLs").
(I have already checked all other posts on the site for the same issue and did not find a fix)
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $AdminName, $Pass
$Path_SpFiles = "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI"
Add-Type -path "$Path_SpFiles\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -path "$Path_SpFiles\Microsoft.SharePoint.Client.dll"
# ------- Connect to SharePoint Site and fetch List Items ----------------
[Net.ServicePointManager]::SecurityProtocol = 'TLS11','TLS12','ssl3'
$site = "https://xyz.sharepoint.com/sites/mco"
$context = New-Object Microsoft.SharePoint.Client.ClientContext($site)
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($AdminName, $Pass)
$context.Credentials = $credentials
$ListName="list_DLs"
$list = $context.Web.Lists.GetByTitle($ListName)
$query = [Microsoft.SharePoint.Client.CamlQuery]::CreateAllItemsQuery(5000)
$items = $list.GetItems($query)
$context.Load($items)
$context.ExecuteQuery()
$MaxItems = $items.count
$SourceFile = "C:\Temp\list_DLs.csv"
$CSVData = Import-CSV -path $SourceFile
foreach ($row in $CSVData)
{
#----------------------------------------------
#Check if the item has previously been added
if ($MaxItems -ne 0)
{
$ItemExist = $items | where{$_.Title -eq $row.PrimarySmtpAddress}
if($ItemExist -ne $null) {Continue}
}
#----------------------------------------------
$ListItemInfo = New-Object Microsoft.SharePoint.Client.ListItemCreationInformation
$Item = $list.AddItem($ListItemInfo)
$Item["Title"] = $row.PrimarySmtpAddress
$Item.Update()
$Context.ExecuteQuery()
Break
}
I know that the $items in being returned correctly, because if I run this snippet of code to iterate through the items I am able to see them correctly. I am just not able to get $ItemExist to work correctly
ForEach ($item in $items)
{
$b = $item["Title"]
$b
Break
}
You can use a CAML query to check if the item is already in the list.
CAML query:
$caml="
<View>
<Query>
<Where><Eq><FieldRef Name='Title' /><Value Type='Text'>1</Value></Eq></Where>
</Query>
</View>
"
$ItemExist = Get-PnPListItem -List $targetList -Query $caml
My test result:
I'm using MongoDb v3.0.3 and want to create a user in a database with admin privileges using powershell. I hook into the C# driver but I don't get very far:
$pathToMongoDbCSharpDriver = "F:\Work\...\mongocsharpdriver.1.9.2\lib\net35"
Add-Type -Path "$pathToMongoDbCSharpDriver\MongoDB.Bson.dll"
Add-Type -Path "$pathToMongoDbCSharpDriver\MongoDB.Driver.dll"
$client = New-Object -TypeName MongoDB.Driver.MongoClient -ArgumentList "mongodb://localhost:30000"
$server = $client.GetServer()
$databaseName = "Dev"
$collectionName = "Settings"
$database = $server.GetDatabase($databaseName)
$collection = $database.GetCollection($collectionName)
$credentials = New-Object -TypeName MongoDB.Driver.MongoCredential("Admin", "password", $true);
$user = New-Object -TypeName MongoDB.Driver.MongoUser($credentials, $false)
$credentials fails because argument 1 it is not a MongoIdentity and I can't find any information about how to create one of these. Any help would be gratefully received
I use all the parameters in the argument list. The following works fine for me:
$Client = New-Object -TypeName MongoDB.Driver.MongoClient -ArgumentList "mongodb://dbuser:dbpass#localhost:27017/test"
I am working on a function that will insert a row into a SQL database. It is basically a simple change log to help me track what is changed on my various SQL instances. As part of this, I want to have the following parameters:
Timestamp
Server
Instance
Change
I've got the Timestamp, Change, and Server all figured out, but the Instance is giving me some trouble. The Server parameter is dynamic, as it pulls a list of SQL servers from my inventory. I then want the value of that parameter to be used in another dynamic parameter, which pulls a list of the instances that are on that server (also from my inventory). Here is what I have for the dynamic portion:
DynamicParam {
if (!(Get-Module sqlps)){ Pop-Location; Import-Module sqlps -DisableNameChecking; Push-Location }
$inventoryinstance = 'ServerName'
$newparams = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary
$server_query = 'SELECT [Name] FROM [ServerInventory].[dbo].[Servers] WHERE [TypeID] = 1 ORDER BY [Name]'
$servers = Invoke-Sqlcmd -serverinstance $inventoryinstance -query $server_query -connectiontimeout 5
# Populate array
$serverlist = #()
foreach ($servername in $servers.Name) {
$serverlist += $servername
}
$attributes = New-Object System.Management.Automation.ParameterAttribute
$attributes.ParameterSetName = "__AllParameterSets"
$attributes.Position = 1
$attributes.Mandatory = $true
$attributes.HelpMessage = "The server the change was made on"
# Server list parameter setup
if ($serverlist){ $servervalidationset = New-Object System.Management.Automation.ValidateSetAttribute -ArgumentList $serverlist }
$serverattributes = New-Object -Type System.Collections.ObjectModel.Collection[System.Attribute]
$serverattributes.Add($attributes)
if ($serverlist){ $serverattributes.Add($servervalidationset) }
$serverob = New-Object -Type System.Management.Automation.RuntimeDefinedParameter("Server", [String], $serverattributes)
$newparams.Add("Server", $serverob)
$instance_query = "SELECT [Name] FROM [ServerInventory].[dbo].[SQLInstances] WHERE [ServerID] = (SELECT [ServerID] FROM [ServerInventory].[dbo].[Servers] WHERE [Name] = '$($PSBoundParameters.Server)')"
$instances = Invoke-Sqlcmd -serverinstance $inventoryinstance -query $instance_query -connectiontimeout 5
# Populate array
$instancelist = #()
foreach ($instancename in $instances.Name) {
$instancelist += $instancename
}
$attributes = New-Object System.Management.Automation.ParameterAttribute
$attributes.ParameterSetName = "__AllParameterSets"
$attributes.Position = 2
$attributes.Mandatory = $false
$attributes.HelpMessage = "The instance the change was made on, do not specify for server-level changes"
# Server list parameter setup
if ($instancelist){ $instancevalidationset = New-Object System.Management.Automation.ValidateSetAttribute -ArgumentList $instancelist }
$instanceattributes = New-Object -Type System.Collections.ObjectModel.Collection[System.Attribute]
$instanceattributes.Add($attributes)
if ($instancelist){ $instanceattributes.Add($instancevalidationset) }
$instanceob = New-Object -Type System.Management.Automation.RuntimeDefinedParameter("Instance", [String], $instanceattributes)
$newparams.Add("Instance", $instanceob)
return $newparams
}
Everything seems to be working, except the value for the instance variable doesn't autocomplete. Is it possible to use the value of one dynamic parameter to generate another?
I have a pretty straight-forward function for grabbing SQL results:
function RunSqlCommand($sql)
{
$connection = $null
$command = $null
try
{
$connectionString = "data source=localhost; integrated security=true"
$connection = New-Object System.Data.SqlClient.SqlConnection($connectionString)
$command = $connection.CreateCommand()
$command.CommandText = $sql
$adapter = New-Object System.Data.SqlClient.SqlDataAdapter($command)
$dataSet = New-Object System.Data.DataSet
$adapter.Fill($dataSet)
$results = $dataSet.Tables | Select-Object -ExpandProperty "Rows"
return $results
}
finally
{
if ($command -ne $null) { $command.Dispose() }
if ($connection -ne $null) { $connection.Dispose() }
}
}
Whenever there are no results, the $results variable is $null. However, when I inspect the return value in the calling method, it magically becomes 0.
Is PowerShell doing something behind the scenes? I really do want to return $null to represent "no results".
$adapter.Fill() returns the number of rows added or refreshed in the dataset.
To fix, you can do this:
[void]$adapter.Fill($dataSet)
or
$adapter.Fill($dataset) | out-null
Is there a way to execute an arbitrary query on a SQL Server using Powershell on my local machine?
For others who need to do this with just stock .NET and PowerShell (no additional SQL tools installed) here is the function that I use:
function Invoke-SQL {
param(
[string] $dataSource = ".\SQLEXPRESS",
[string] $database = "MasterData",
[string] $sqlCommand = $(throw "Please specify a query.")
)
$connectionString = "Data Source=$dataSource; " +
"Integrated Security=SSPI; " +
"Initial Catalog=$database"
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$command = new-object system.data.sqlclient.sqlcommand($sqlCommand,$connection)
$connection.Open()
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null
$connection.Close()
$dataSet.Tables
}
I have been using this so long I don't know who wrote which parts. This was distilled from others' examples, but simplified to be clear and just what is needed without extra dependencies or features.
I use and share this often enough that I have turned this into a script module on GitHub so that you can now go to your modules directory and execute git clone https://github.com/ChrisMagnuson/InvokeSQL and from that point forward invoke-sql will automatically be loaded when you go to use it (assuming your using PowerShell v3 or later).
You can use the Invoke-Sqlcmd cmdlet
Invoke-Sqlcmd -Query "SELECT GETDATE() AS TimeOfQuery;" -ServerInstance "MyComputer\MyInstance"
http://technet.microsoft.com/en-us/library/cc281720.aspx
This function will return the results of a query as an array of powershell objects so you can use them in filters and access columns easily:
function sql($sqlText, $database = "master", $server = ".")
{
$connection = new-object System.Data.SqlClient.SQLConnection("Data Source=$server;Integrated Security=SSPI;Initial Catalog=$database");
$cmd = new-object System.Data.SqlClient.SqlCommand($sqlText, $connection);
$connection.Open();
$reader = $cmd.ExecuteReader()
$results = #()
while ($reader.Read())
{
$row = #{}
for ($i = 0; $i -lt $reader.FieldCount; $i++)
{
$row[$reader.GetName($i)] = $reader.GetValue($i)
}
$results += new-object psobject -property $row
}
$connection.Close();
$results
}
Here's an example I found on this blog.
$cn2 = new-object system.data.SqlClient.SQLConnection("Data Source=machine1;Integrated Security=SSPI;Initial Catalog=master");
$cmd = new-object system.data.sqlclient.sqlcommand("dbcc freeproccache", $cn2);
$cn2.Open();
if ($cmd.ExecuteNonQuery() -ne -1)
{
echo "Failed";
}
$cn2.Close();
Presumably you could substitute a different TSQL statement where it says dbcc freeproccache.
If you want to do it on your local machine instead of in the context of SQL server then I would use the following. It is what we use at my company.
$ServerName = "_ServerName_"
$DatabaseName = "_DatabaseName_"
$Query = "SELECT * FROM Table WHERE Column = ''"
#Timeout parameters
$QueryTimeout = 120
$ConnectionTimeout = 30
#Action of connecting to the Database and executing the query and returning results if there were any.
$conn=New-Object System.Data.SqlClient.SQLConnection
$ConnectionString = "Server={0};Database={1};Integrated Security=True;Connect Timeout={2}" -f $ServerName,$DatabaseName,$ConnectionTimeout
$conn.ConnectionString=$ConnectionString
$conn.Open()
$cmd=New-Object system.Data.SqlClient.SqlCommand($Query,$conn)
$cmd.CommandTimeout=$QueryTimeout
$ds=New-Object system.Data.DataSet
$da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
[void]$da.fill($ds)
$conn.Close()
$ds.Tables
Just fill in the $ServerName, $DatabaseName and the $Query variables and you should be good to go.
I am not sure how we originally found this out, but there is something very similar here.
There isn't a built-in "PowerShell" way of running a SQL query. If you have the SQL Server tools installed, you'll get an Invoke-SqlCmd cmdlet.
Because PowerShell is built on .NET, you can use the ADO.NET API to run your queries.
Invoke-Sqlcmd -Query "sp_who" -ServerInstance . -QueryTimeout 3
To avoid SQL Injection with varchar parameters you could use
function sqlExecuteRead($connectionString, $sqlCommand, $pars) {
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$connection.Open()
$command = new-object system.data.sqlclient.sqlcommand($sqlCommand, $connection)
if ($pars -and $pars.Keys) {
foreach($key in $pars.keys) {
# avoid injection in varchar parameters
$par = $command.Parameters.Add("#$key", [system.data.SqlDbType]::VarChar, 512);
$par.Value = $pars[$key];
}
}
$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataset) | Out-Null
$connection.Close()
return $dataset.tables[0].rows
}
$connectionString = "connectionstringHere"
$sql = "select top 10 Message, TimeStamp, Level from dbo.log " +
"where Message = #MSG and Level like #LEVEL"
$pars = #{
MSG = 'this is a test from powershell'
LEVEL = 'aaa%'
};
sqlExecuteRead $connectionString $sql $pars
You can even format string and pass parameters as you want.
case "ADDSQLSERVERUSER":
//0 = coprorateName;
//1 = user password
//2 = servername
command = #"$sqlQuery = Use JazzUWS_'{0}'
Create login UWSUser_'{0}' with password='{1}';
Create user UWSUser_'{0}' for login UWSUser_'{0}';
Grant Execute to UWSUser_'{0}';
Use ReportSvrUWS_'{0}'
Create user UWSUser_'{0}' for login UWSUser_'{0}';
Grant Execute to UWSUser_'{0}';
Invoke-Sqlcmd -Query $sqlQuery -ServerInstance '{2}'";
break;
C# Code for remote execution(you can organize your way)
string script = PowershellDictionary.GetPowershellCommand("ADDSQLSERVERUSER");
script = String.Format(script, this.CorporateName, password, this.SQLServerName)
PowerShellExecution.RunScriptRemote(_credentials.Server, _credentials.Username, _credentials.Password, new List<string> { script });
You could use the best SQL Server module around: DBATOOLS. You would also benefit from running a query to multiple sql instances.
Install-Module dbatools -Scope CurrentUser
$sql = 'SQL1','SQL1\INSTANCE1','SQL2'
$query = "SELECT 'This query would run on all SQL instances'"
Invoke-DbaQuery -SqlInstance $sqlinstances -Query $query -AppendServerInstance
