Oracle SCM Icon Oracle SCM ODBC Driver

The Oracle SCM ODBC Driver is a powerful tool that allows you to connect with live data from Oracle SCM, directly from any applications that support ODBC connectivity.

Access Oracle SCM data like you would a database - read, write, and update Oracle SCM 0, etc. through a standard ODBC Driver interface.

Build a Simple VCL Application for Oracle SCM Data


How to build a simple VCL Application to view Oracle SCM data in RAD Studio using the CData ODBC Driver for Oracle SCM.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Oracle SCM, you gain access to live Oracle SCM data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve Oracle SCM data. This article will walk through connecting to Oracle SCM and creating a simple VCL application with the Form Designer.

Create a Connection to Oracle SCM Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

The following connection properties are required to connect to Oracle SCM data.

  • Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
  • User: The username of your Oracle Cloud service account.
  • Password: The password of your Oracle Cloud service account.

You can then follow the steps below to use the Data Explorer to create a FireDAC connection to Oracle SCM data.

  1. In a new VCL Forms application, expand the FireDAC node in the Data Explorer.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Oracle SCM.

Create VCL Applications with Connectivity to Oracle SCM Data

Follow the procedure below to start executing queries to Oracle SCM data from a simple VCL application that displays the results of a query in a grid.

  1. Drop a TFDConnection component onto the form and set the following properties:

    • ConnectionDefName: Select the FireDAC connection to Oracle SCM data.
    • Connected: Select True from the menu and, in the dialog that appears, enter your credentials.

  2. Drop a TFDQuery component onto the form and set the properties below:

    • Connection: Set this property to the TFDConnection component, if this component is not already specified.

    • SQL: Click the button in the SQL property and enter a query. For example:

      SELECT CarrierId, CarrierName FROM Carriers WHERE ActiveFlag = 'false'
    • Active: Set this property to true.

  3. Drop a TDataSource component onto the form and set the following property:

    • DataSet: In the menu for this property, select the name of the TFDQuery component.

  4. Drop a TDBGrid control onto the form and set the following property:

    • DataSource: Select the name of the TDataSource.
  5. Drop a TFDGUIxWaitCursor onto the form — this is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
