I am looking for some Power Shell script to fetch data from a SQL Server table using windows authentication and write it back to .txt file.
I am very new to Power Shell thing and never worked on this before. So if somebody could guide me in this effort.
Thanks to both of you guys. I am able to google and make a script working according to requirement.
Here it is
#Script parameters
param(
#Name of MS SQL Server instance
[parameter(Mandatory=$true,
HelpMessage="Specify the SQL Server name where will be run a T-SQL code",Position=0)]
[String]
[ValidateNotNullOrEmpty()]
$server = $(throw "sqlserver parameter is required."),
#Database name for execution context
[parameter(Mandatory=$true,
HelpMessage="Specify the context database name",Position=1)]
[String]
[ValidateNotNullOrEmpty()]
$dbname = $(throw "dbname parameter is required.")
)
$connectionString = “Server=$server;Database=$dbname;Integrated Security=True;”
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$query = “SELECT type,name FROM sys.tables"
$command = $connection.CreateCommand()
$command.CommandText = $query
$result = $command.ExecuteReader()
$table = new-object “System.Data.DataTable”
$table.Load($result)
$table | Out-File D:\test\swedes$dbname.txt
$connection.Close()
Now I am looking for a way to run this script on a remote SQL Server and save the results.
I am googling about this but still if someone knows a way to run this script using SSIS please help.

Hi i'm completely new to this ,i want to store capacity in particular format. Mycode showing correct format but in SQL database its value is getting changed to default.
My code:
$SSDCapacity= Get-Disk | select Size
foreach($size in $SSDCapacity)
{
$variable = $size.Size.ToString()
}
$result = $variable.SubString(0,3)
$result
Above code shows output as 512 in powershell.
But when i store it in database its showing in default form #{Size=512110190590}
I have a insert query for SQL Part
$InsertQuery="INSERT INTO [$($Database)].[dbo].[$($name)]
([ComputerName],[Model],[SSDCapacity])
VALUES('$ComputerNameValue','$ModelValue','$result')
"
then i'm just calling above query for insert
#Insert into Table
$SqlCmd.CommandText = $InsertQuery
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
#Creating Dataset
$Datatable = New-Object "System.Data.Datatable"
$result = $SqlCmd.ExecuteNonQuery()
$conn.Close()
So how can i store in format powershell shows.
I might be missing out some silly things here.
Any help will be thankfull.
You could do that in one line using DBATOOLS
Install-Module dbatools -Scope CurrentUser #only once
Get-DbaDiskSpace|select ComputerName, Name, Capacity, Free|Write-DbaDataTable -SqlInstance $sql -Database TEMPDB -Table disk -AutoCreateTable
I have a code running to import CSV files into a Access database. However now I have access to a SQL server and want to use the same code if possible, but no idea what to change to adapt the code
I have a set of running code which uses a connection string I add parameters and it works.
$connectionString="Provider=Microsoft.Ace.OLEDB.12.0; Data Source=$inputDatabase"
$conn = New-Object System.Data.OleDb.OleDbConnection($connectionString)
$conn.Open()
$cmd = $Conn.CreateCommand()
$cmd.CommandText = "INSERT INTO [Tabl1]([date],[zone],[location],[Plugin ID],[CVE],[CVSS],[Risk],[Host],[Protocol],[Port],[Name])
VALUES(#date, #zone, #location, #PluginID, #CVE, #CVSS, #Risk,#Host,#Protocol,#Port,#Name)"```
[void]$cmd.Parameters.Add('#date', [System.Data.OleDb.OleDbType]::DateTime)
[void]$cmd.Parameters.Add('#zone', [System.Data.OleDb.OleDbType]::VarChar)
both code snippets above show how I set up my connection string, and a quick example of how 2 values are set with their corresponding variable type, it is not the whole code . but the snippets I know I need to change to make it work with an SQL server, the main issue being that i dont know which $connectionstring to use with an SQL server, or for example how do I make it so the data source points to the SQL server network address and uses windows authentication.
And on the second code snippet, which type of format do I use, I knwo the variable types but I assume that if I change from ace.oledb.12 , i should change the oldebtype segment. The SQL server is on SQL 13.0.5426
You'll need to update your connection string. Assuming you're using Windows authentication:
$ConnectionString = 'Data Source={0};Initial Catalog={1};Integrated Security=SSPI' -f $ServerInstanceName, $DatabaseName
And you should use the built-in SQL Server client class, System.Net.SqlClient, instead of OLEDB classes.
$conn = New-Object System.Data.SqlClient.SqlConnection $connectionString
And you'll want to update your parameter types:
[void]$cmd.Parameters.Add('#date', [System.Data.SqlDbType]::DateTime)
[void]$cmd.Parameters.Add('#zone', [System.Data.SqlDbType]::VarChar)
Everything else should be more or less identical.
Here's a working PowerShell script that connects to an SQL Server database, fetches data, and fills a data table:
$SqlQuery = 'SELECT * FROM Student WHERE Student_Id = #student_id'
$ConnectionString = 'Data Source={0};Initial Catalog={1};Integrated Security=True' -f $SqlServer, $Database
$SqlConnection = New-Object -TypeName System.Data.SqlClient.SqlConnection -ArgumentList $ConnectionString
$SqlCommand = New-Object -TypeName System.Data.SqlClient.SqlCommand -ArgumentList $SqlQuery, $SqlConnection
$SqlCommand.Parameters.Add('#student_id', [System.Data.SqlDbType]::VarChar, 10).Value = $Student_Id
$DataTable = New-Object -TypeName System.Data.DataTable -ArgumentList 'Student'
try {
$SqlConnection.Open()
$SqlDataReader = $SqlCommand.ExecuteReader()
$DataTable.Load($SqlDataReader)
}
finally {
$SqlConnection.Close()
}
$DataTable
I am new to this but trying to get it worked out, hoping to find some advice here.
My setup:
Excel 2016 64 Bit
SQL Server 2014 Import and Export Data (64-Bit)
Windows 7 64 Bit
Windows PowerShell ISE (x86)
Microsoft OLE DB Provider for SQL Server
I can export my SQL database perfectly into excel, now I'm just trying to automate it. Here is the code I am currently using:
PowerShell lines
$serverName = "E2\E2SQL";
$databaseName = "*****";
$uid ="*****"
$pwd = "*****"
#the save location for the new Excel file
$filepath = "C:\Users\Bob\Desktop\TEST.xls";
#create a Dataset to store the DataTable
$dataSet = new-object "System.Data.DataSet" "TEST"
#create a Connection to the SQL Server database
$cn = new-object System.Data.SqlClient.SqlConnection "server=$serverName;database=$databaseName;Integrated Security=false; User ID = $uid; Password = $pwd;"
$query= "SELECT JobNo FROM Online;"
#Create a SQL Data Adapter to place the resultset into the DataSet
$dataAdapter = new-object "System.Data.SqlClient.SqlDataAdapter" ($query, $cn)
$dataAdapter.Fill($dataSet) | Out-Null
#close the connection
$cn.Close()
I get an error on
$dataSet = new-object "System.Data.DataSet" "TEST"
I don't really understand that line of code... Anyway any thoughts on how to get this working are greatly appreciated!
I would also be open to exporting to a CSV if that makes it easier.
I have a txt file(load_check_run_bmu.sql) that contains the following sql code.
RESTORE DATABASE Address from disk='C:\dir\path\address.bmu'
Use Client
GO
Select f_name
From
cst.name
USE wage
GO
Exec sp_salary
Use Client
GO
Select f_name
From
cst.name
I then have a batch file that contains:
sqlcmd -S .\NorthWind -i"C:\scripts\load_check_run_bmu.sql"
What I need to do is be able to execute all of necessary SQL commands in a powershell script and eliminate the sql txt file and the sqlcmd batch file
I'm aware I would need the following code, but I am struggling on how to convert the T-SQL script into something usable for the $SqlCmd.CommandText variable
$sqlServer = "."
$sqlDBName = "NorthWind"
$sqlConnectionString ="Server = $sqlServer; Database = $sqlDBName; Integrated Security = True"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = $sqlConnectionString
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
**$SqlCmd.CommandText = [SQL Command(s)]<====( Need assistance populating this)**
$SqlCmd.Connection = $SqlConnection
$SqlCmd.Connection.Open()
$ReturnValue = $SqlCmd.ExecuteNonQuery()
$SqlCmd.Connection.Close()
Put the T-SQL .txt file into a string using double quotes " and take out the GO statements. You can also end each statement with ; to ensure queries do not get mixed up and the queries should run without failure:
$TSQLString = "RESTORE DATABASE Address from disk='C:\dir\path\address.bmu';
Use Client;
Select f_name
From
cst.name;
USE wage;
Exec sp_salary;
Use Client;
Select f_name
From
cst.name;"
Then use the string for your variable:
$SqlCmd.CommandText = $TSQLString
It also looks like you using multiple databases in the query above. If this is the case this approach might not work has you are connecting to a single database with the statement below.
$sqlConnectionString ="Server = $sqlServer; Database = $sqlDBName; Integrated Security=True"
To get round this you will need to open up a connection for each statement. So you might want to make a function that connects to a server\database and runs a given query e.g (Run-Sql would be the function you need to create).
$SQLQuery1 = "RESTORE DATABASE Address from disk='C:\dir\path\address.bmu';"
$SQLQuery2 = "Select f_name From cst.name;"
$SQLQuery3= "Exec sp_salary;"
$SQLQuery4 = "Select f_name From cst.name;"
# Run all statments
Run-SQL -query $SQLQuery1 -DB "NorthWind" -Server "."
Run-SQL -query $SQLQuery2 -DB "Client" -Server "."
Run-SQL -query $SQLQuery3 -DB "wage" -Server "."
Run-SQL -query $SQLQuery4 -DB "Client" -Server "."
Use invoke-SQLCMD

I would like to execute a stored procedure from Powershell (v2) against a SQL Server 2008 database. Coming from using C# as my primary language, I'm doing it in that fashion. For example, when I need to run a sproc that doesn't return results, here is what I'm doing now:
$con = new-object System.Data.SqlClient.SqlConnection($connectionString)
$cmd = new-object System.Data.SqlClient.SqlCommand("exec MySproc", $con)
$con.Open()
$cmd.ExecuteNonQuery()
$cn.Close()
While perhaps TMTOWTDI, I'd like to know the best way.
I should mention that I'm already familiar with T-SQL and the System.Data namespace. This is really a question about Powershell.
For straight PowerShell I would go with code like you and Andomar have written. However if you are using the PowerShell Community Extensions there are some cmdlets for working with ADO e.g.:
$conn = 'Data Source=.\SQLEXPRESS;Initial Catalog=pubs;Integrated Security=SSPI'
$ds = Invoke-AdoCommand -ProviderName SqlClient -ConnectionString $conn `
-CommandText 'Select * from Authors' -AsDataSet
$ds.Tables
au_id : 172-32-1176
au_lname : White
au_fname : Johnson
phone : 408 496-7223
address : 10932 Bigge Rd.
city : Menlo Park
state : CA
zip : 94025
contract : True

I have a Windows Server 2008 with PowerShell 2.0 and SQL Server 2008 and I have been able to use the Invoke-SqlCmd to execute sql against a database.
You'll need to add the snapins with these two commands:
Add-PSSnapin SqlServerCmdletSnapin100
Add-PSSnapin SqlServerProviderSnapin100
After doing this the Invoke-sqlcms will be avaliable to your PowerShell session take a look at http://technet.microsoft.com/en-us/library/cc281720.aspx for examples of using the invoke-sqlcmd
ExecuteNonQuery() runs a stored procedure but does not ask for results. You'd have to use ExecuteReader() for a rowset, or ExecuteScalar() for one row with one value.
Here's an example from this nice tutorial:
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "..."
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "sp_helpdb"
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSet.Tables[0]
