Automate MySQL Integration Tasks from PowerShell

The CData Cmdlets for MySQL are standard PowerShell cmdlets that make it easy to accomplish data cleansing, normalization, backup, and other integration tasks by enabling real-time and bidirectional access to MySQL.

PowerShell Cmdlets or ADO.NET Provider?

The Cmdlets are not only a PowerShell interface to MySQL, but also an SQL interface; this tutorial shows how to use both to create, retrieve, update, and delete MySQL data. We also show examples of the ADO.NET equivalent, which is possible with the CData ADO.NET Provider for MySQL. To access MySQL data from other .NET applications, like LINQPad, use the CData ADO.NET Provider for MySQL.

Once you have acquired the necessary connection properties, accessing MySQL data in PowerShell can be enabled in three steps.

The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.

PowerShell

1. Install the module:

   Install-Module MySQLCmdlets

2. Connect:

   $mysql = Connect-MySQL -User "$User" -Password "$Password" -Database "$Database" -Server "$Server" -Port "$Port"

3. Search for and retrieve data:

   $shipcountry = "USA" $orders = Select-MySQL -Connection $mysql -Table "Orders" -Where "ShipCountry = `'$ShipCountry`'" $orders

   You can also use the Invoke-MySQL cmdlet to execute SQL commands:

   $orders = Invoke-MySQL -Connection $mysql -Query 'SELECT * FROM Orders WHERE ShipCountry = @ShipCountry' -Params @{'@ShipCountry'='USA'}

ADO.NET

1. Load the provider's assembly:

   [Reflection.Assembly]::LoadFile("C:\Program Files\CData\CData ADO.NET Provider for MySQL\lib\System.Data.CData.MySQL.dll")

2. Connect to MySQL:

   $conn= New-Object System.Data.CData.MySQL.MySQLConnection("User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;") $conn.Open()

3. Instantiate the MySQLDataAdapter, execute an SQL query, and output the results:

   $sql="SELECT ShipName, Freight from Orders" $da= New-Object System.Data.CData.MySQL.MySQLDataAdapter($sql, $conn) $dt= New-Object System.Data.DataTable $da.Fill($dt) $dt.Rows | foreach { Write-Host $_.shipname $_.freight }
