I keep getting an error about "\" on the line with the $conn.Execute() when I try and do this. I assume it has to do with character escaping and maybe I am doing it wrong.
Is there a better way to do this with PowerShell if I just need to get the name field of any record from _users and output it to CSV?
Eventually I will be adding more to this to loop through each record in the CSV and execute a tabcmd to remove all the users that are unlicensed.

This did like 99% of what I need; I just have to process the csv now and drop the first two lines. The first line is a type info message and the second is the column header.
I'm trying to create a script for querying a database, extract data and put it to an .csv file. This is the part of interest of the code:
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$command = $connection.CreateCommand()
$command.CommandText = $query
$result = $command.ExecuteReader()
###########################
##PRSENTAZIONE DEI RISULTATI##
$table = New-Object System.Data.DataSet
$table.Load($result)
$table | Export-Csv -Path $fileName -Delimiter "|" -NoTypeInformation
I have 2 problems:
On Windows 2003 PowerShell -Delimiter parameter is not present
If I delete that parameter the ouput file presents a wrong format date.
username, ipaddress, yyyy-mm-dd hh:mm:ss (running the same query in Management Studio), username, ipaddress, "dd/mm/yyyy hh.mm.ss" (apexes included ; printing the $table).
How can I solve this?
I have created a test database in SQL Server 2016 Express, it holds 1 table labeled drivers.
I use PowerShell to perform ciminstance query of installed drivers, then insert those values into the test database driver table. (the insert works as expected)
The issue I have is attempting to update the driver table, only the last object is inserted into the database 40 times(that is how many drivers are returned from the ciminstance query). I have created 2 PowerShell scripts
Insert values
Update values
Stumped!
$database = 'test'
$server = 'groga\sqlExpress'
$table = 'dbo.Driver'
$SQLServer = "groga\sqlExpress"
$SQLDBName = "test"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database =
$SQLDBName; Integrated Security = True"
$SqlConnection.Open()
$today = Get-Date
$drivers = gcim win32_pnpsigneddriver -Property *
$model = gcim win32_computersystem -Property *
foreach($driver in $drivers)
{
if(!($driver.Description -match "Generic") -and $driver.Manufacturer -
notmatch 'Microsoft|Standard|Generic' -and $driver.DriverDate -ne $null)
{
$count = New-Object psobject -Property #{
'Date' = $driver.DriverDate
'Manufacturer' = $driver.Manufacturer
'Version' = $driver.DriverVersion
'PackageID' = "0"
'SKU' = $model.SystemSKUNumber
'Model' = $model.Model
'Today' = $today}
$col1 = $count.Date
$col2 = $count.Manufacturer
$col3 = $count.Version
$col4 = $count.PackageID
$col5 = $count.SKU
$col6 = $count.Model
$col7 = $count.Today
$update = #"
UPDATE $table
SET [Date]='$col1',
[Manufacturer]='$col2',
[Version]='$col3',
[PackageID]='$col4',
[SKU]='$col5',
[Model]='$col6',
[Today]='$col7'
"#
$dbwrite = $SqlConnection.CreateCommand()
$dbwrite.CommandText = $update

}
}
$Sqlconnection.Close()
The UPDATE statement will apply to all rows that are matched by the query. So what your script is doing is setting ALL rows in the table to info for a driver then doing the same for the whole list.
You will need to determine the fields which uniquely identify each driver and then filter your query down to that. Looking at sample driver info, this could be Date, Manufacturer, Device Name (something you would need to add to your schema), DriverVersion.
Example with just Date, Manufacturer, DriverVersion:
$update = #"
UPDATE $table
SET [PackageID] = '$col4'
[SKU]='$col5',
[Model]='$col6',
[Today]='$col7'
WHERE [Date] = '$col1' AND [Manufacturer]='$col2' AND [Version]='$col3'

I have script, which connect to db. I need get technical info about execute script. Or when in my sql srcipt exist mistake,I see very scant information. But I need detail of error. How can I get more detail info?
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$query = "SELECT * FROM Animal"
$command = $connection.CreateCommand()
$command.CommandText = $query
$result = $command.ExecuteReader()
$table = new-object “System.Data.DataTable”
$table.Load($result)
$table
//how get info
$connection.Close()
After your code executes run Error[0] | fl -Force to get the details of (last) error.
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
