Deleting data records by using SQL

Suggest edit Updated on January 29, 2021

Use the ExecuteRDB SQL API to delete records in your database through an activity, without requiring you to delete a data object in Pega Platform.

Before you begin: Create an activity. For more information, see Creating an activity.
  1. In the header of Dev Studio, click CreateTechnicalActivity.

  2. In the activity rule form, enter a label, select an application and the associated ruleset, and then click Create and open.

  3. On the Steps tab, in the Label field, enter a unique identifier for the step.

  4. In the Method list, select Java.

  5. To the left of the Method list, click the Expand icon.

  6. In the Method Parameters section, in the Java Source field, enter an ExecuteRDB method.

    For example:
    String delete = "delete from {class:" + <YourClassName>  + "} where id = \\{fn concat('a', 'bc')\\}";
    ClipboardPage listPage = 
    tools.getThread().createPage("Code-Pega-List", "MyPage");
    listPage.putString(".pxObjClass", <YourClassName>);
    listPage.putString(".pyMaxRecords", String.valueOf(0));
    try{tools.getDatabase().executeRDB(delete , listPage));
    catch(Exception err)
    {oLog.infoForced("Exception occurred");
    <YourClassName> is the name of the class into which you want to insert records.
  7. Click Save.

  8. Start the insert of records into your internal database by running the activity.
