FireDAC Components for Sybase

Build 21.0.8137

Establishing a Connection

You can create and manage connections with the Data Explorer and the FireDAC Connection Editor wizards. See Connection Definitions for more information on creating connections from code and creating persistent, private, or temporary connections.

Connecting to Sybase

To connect to the 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.

Authenticating to Sybase

Sybase supports several methods for authentication including basic, Kerberos, and, LDAP.

Connect Using Basic Authentication

Set the AuthScheme to Basic 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 basic authentication.

Connect Using Kerberos Authentication

To leverage Kerberos authentication, begin by enabling it via the following connection property:

  • AuthScheme: Set to Kerberos will be used for authentication to Sybase.
See Using Kerberos information regarding the connection properties that need to be set for 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

Using the FireDAC Connection Editor

Complete the following steps to use the FireDAC Connection Editor to assign a Sybase connection to a TFDConnection object:

  1. Open a project and drop a TFDPhysCDataSybaseDriverLink from the Tool Palette onto the Form Designer.
  2. Drop a TFDConnection object onto the Form Designer.
  3. Double-click the TFDConnection and select CDataSybase in the Driver Id menu.
  4. Define the necessary connection properties.
  5. To execute ad-hoc SQL statements based on this connection, enter SQL commands on the SQL Script tab.
  6. In the Form Designer, select the TFDConnection object and set the Connected property to true.

Using the Data Explorer

Complete the following steps to use the Data Explorer to define persistent connections that can be shared across applications and projects:

  1. Click View > Tool Windows > Data Explorer in RAD Studio and expand the FireDAC node.
  2. Right-click the CData Sybase Data Source node and click Add New Connection.
  3. Enter a name for the connection. The FireDAC Connection Editor opens.

Working with Persistent Connections

The connections you define in the Data Explorer can be assigned to a TFDConnection object by specifying the connection name in the TFDConnection object's ConnectionDefName property.

Browsing Data and Metadata

The Data Explorer also provides options for browsing Sybase objects at design time:

  • Expand the CData Sybase Data Source node in the Data Explorer to view the defined connections.
  • Expand a connection node to find the database objects available for a connection.
  • Drill down to a database object to find metadata such as primary keys and foreign keys.
  • To display data, double-click a table or view or right-click and click View.
