Pipe Sybase Data to CSV in PowerShell

The CData Cmdlets Module for Sybase is a standard PowerShell module offering straightforward integration with Sybase. Below, you will find examples of using our Sybase Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your Sybase Data

To connect to Sybase, specify the following connection properties:

• Server: Set this to the name or network address of the Sybase database instance.
• Database: Set this to the name of the Sybase database running on the specified Server.

Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

Sybase supports several methods for authentication including Password and Kerberos.

Connect Using Password Authentication

Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

• User: Set this to the username of the authenticating Sybase user.
• Password: Set this to the username of the authenticating Sybase user.

Connect using LDAP Authentication

To connect with LDAP authentication, you will need to configure Sybase server-side to use the LDAP authentication mechanism.

After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

Connect Using Kerberos Authentication

To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos. See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

You can find an example connection string below: Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

$conn = Connect-Sybase  -User "$User" -Password "$Password" -Server "$Server" -Database "$Database" -Charset "$Charset"

Selecting Data

Follow the steps below to retrieve data from the Products table and pipe the result into to a CSV file:

Select-Sybase -Connection $conn -Table Products | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myProductsData.csv -NoTypeInformation

You will notice that we piped the results from Select-Sybase 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.

Deleting Data

The following line deletes any records that match the criteria:

Select-Sybase -Connection $conn -Table Products -Where "ProductName = Konbu" | Remove-Sybase

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 Sybase, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyProductsUpdates.csv | %{
  $record = Select-Sybase -Connection $Sybase -Table Products -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-Sybase -Connection $sybase -Table Products -Columns ("Id","ProductName") -Values ($_.Id, $_.ProductName) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-Sybase -Connection $sybase -Table Products -Columns ("Id","ProductName") -Values ($_.Id, $_.ProductName)
  }
}

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!
