Use standard PowerShell cmdlets to access MySQL tables.
The CData Cmdlets Module for MySQL is a standard PowerShell module offering straightforward integration with MySQL. Below, you will find examples of using our MySQL Cmdlets with native PowerShell cmdlets.
Creating a Connection to Your MySQL Data
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.
$conn = Connect-MySQL -User "$User" -Password "$Password" -Database "$Database" -Server "$Server" -Port "$Port"
Selecting Data
Follow the steps below to retrieve data from the Orders table and pipe the result into to a CSV file:
Select-MySQL -Connection $conn -Table Orders | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myOrdersData.csv -NoTypeInformation
You will notice that we piped the results from Select-MySQL into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.
The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.Deleting Data
The following line deletes any records that match the criteria:
Select-MySQL -Connection $conn -Table Orders -Where "ShipCountry = USA" | Remove-MySQL
Inserting and Updating Data
The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into MySQL, checking first whether a record already exists and needs to be updated instead of inserted.
Import-Csv -Path C:\MyOrdersUpdates.csv | %{ $record = Select-MySQL -Connection $MySQL -Table Orders -Where ("Id = `'"+$_.Id+"`'") if($record){ Update-MySQL -Connection $mysql -Table Orders -Columns ("ShipName","Freight") -Values ($_.ShipName, $_.Freight) -Where ("Id = `'"+$_.Id+"`'") }else{ Add-MySQL -Connection $mysql -Table Orders -Columns ("ShipName","Freight") -Values ($_.ShipName, $_.Freight) } }
As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
