Connect to Sybase Data from PowerBuilder
This article demonstrates how to access Sybase data from Appeon PowerBuilder using the CData ADO.NET Provider for Sybase.
This article demonstrates using the CData ADO.NET Provider for Sybase in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.
This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Sybase to perform reads and writes.
- In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:
User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;Charset=iso_1;
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 - Add the DataGrid control from the .NET controls.
-
Configure the columns of the DataGrid control. Below are several columns from the Account table:
<DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> - Add a reference to the CData ADO.NET Provider for Sybase assembly.
Connect the DataGrid
Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:
System.Data.CData.Sybase.SybaseConnection conn
conn = create System.Data.CData.Sybase.SybaseConnection(connectionString)
System.Data.CData.Sybase.SybaseCommand comm
comm = create System.Data.CData.Sybase.SybaseCommand(command, conn)
System.Data.DataTable table
table = create System.Data.DataTable
System.Data.CData.Sybase.SybaseDataAdapter dataAdapter
dataAdapter = create System.Data.CData.Sybase.SybaseDataAdapter(comm)
dataAdapter.Fill(table)
datagrid1.ItemsSource=table.DefaultView
The code above can be used to bind data from the specified query to the DataGrid.
