insert values into SQL Server database

Start by opening a database connection

$server = "yourServer\mssql2019"
$database = "yourDatabase"
$table = " yourTable"
$ConnectionString = "Server=$server;Database=$database;Integrated Security=True;MultipleActiveResultSets=True"
try
{
    $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
    $SqlConnection.ConnectionString = $ConnectionString
    $cmd = New-Object System.Data.SqlClient.sqlCommand
    $cmd.connection = $SqlConnection
    $cmd.Connection.Open()
}
catch [System.Exception]
{
    Write-Host $_.Exception.Message -ForegroundColor Yellow
}

Normally the following might now be done inside a loop (not shown here)
If we don't clear the parameters now using .Parameters.Clear() immediately below from when we set them during an earlier iteration of the loop further below, the system will complain because it thinks we're trying to add the same field again from that earlier iteration (after the 1st iteration, anyway.) Trying to clear using $null won't work

$cmd.Parameters.Clear()

Now start to compose the insert command. We're inserting 4 fields.

$cmd.CommandText = "insert into $table (fileName, location,system,URL) values (@fileName,@location,@system,@URL)"

The "old" way we might have done this was just to put the values we wanted inserted directly into "values" part of the statement above. But using the "@" above and then filling in those parameters below helps us avoid problems with embedded single quotes and are more secure with regard to SQL injection attackes
The | Out-Null statements at the end of each .Parameters.Add() commands below prevents a whole bunch of annoying verbiage from going to your console

$cmd.Parameters.Add("@fileName",$attachment) | Out-Null
$cmd.Parameters.Add("@location",$location) | Out-Null
$cmd.Parameters.Add("@system",$system) | Out-Null
$cmd.Parameters.Add("@URL",$link) | Out-Null

Now that we've properly cued up our insert statement, try to run it:

try
{
    $cmd.ExecuteNonQuery() | Out-Null
}
catch [System.Data.SqlClient.SqlException]
{
    Write-Host "Problem: $($_.Exception.Message)" -ForegroundColor Red
}
catch [System.Exception]
{
    # A generic error occurred somewhere in the try area.
    Write-Host "Some other error occurred: $($_.Exception.Message)" -ForegroundColor Red
}

Once we're done with our loop, close the database connection

$cmd.Connection.Close()

log into SQL Server database, can't using non-integrated security - make sure your connection string includes, ";Trusted_Connection = yes"

MS Access database (.accdb), open/read/write

$mytemp = [environment]::getfolderpath("mydocuments")
$filename = "$mytemp\companies.accdb"
$conn = New-Object System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.16.0;Data Source=$filename;Persist Security Info=False")
$conn.Open()
# read
$cmd=$conn.CreateCommand()
$cmd.CommandText="Select company.* from company;"
"connection is: $($conn.State)"
$rdr = $cmd.ExecuteReader()
$dt = New-Object System.Data.Datatable
$dt.Load($rdr)
$dt
# write
$cmd2 = $conn.CreateCommand()
$cmd2.CommandText ="INSERT into Company (CompanyName) values('Jumbotron')"
$cmd2.ExecuteNonQuery()
$conn.Close()
"connection is: $($conn.State)"

read from Azure DB

$database = "SourceOfAll"
$ServerInstance = "sourceOfAll.database.windows.net"
$Username = "readerGuy"
$password = "yuulNeverGess!"
 
$query = "select FirstName, LastName, DisplayName, UserPrincipalName
from users
where domain = jupiter.com'"
$results = Invoke-Sqlcmd -ServerInstance $ServerInstance -Database $database -Username $Username -Password $Password -Query $query
 
foreach ($result in $results) {
    "$($result.DisplayName)"
}

almost the same for insert, update; just different SQL
