deleteByExample()

Use deleteByExample() to delete big object data from your org using an sObject as a template for what to delete. All data in a big object matching the values in the sObject templates are deleted.

Syntax

1DeleteByExampleResult[] = connection.deleteByExample(sObject[] sObjects);

Rules and Guidelines

When deleting data, consider the following rules and guidelines:

Your client application must be logged in with sufficient access rights to delete individual objects within the specified object. For more information, see Factors that Affect Data Access.
You can't delete records for multiple object types in one call if one of those types is related to a feature in the Setup area in Salesforce. The only exceptions are the following objects:
- Custom settings objects, which are similar to custom objects. For more information, see Create Custom Settings in Salesforce Help.
- GroupMember
- Group
- User

Basic Steps for Deleting Data

Deleting data involves these basic steps.

Define an sObject using all the fields that make up the index of the big object.
Specify the values for each field.
Call deleteByExample(), passing in the sObject you created.
Process the results in the DeleteByExampleResult[] to verify whether the records have been successfully deleted.

Repeating a successful deleteByExample() operation results in success, even if the data has already been deleted.

Note

Sample Code—Custom Big Objects

This sample shows how to delete records in a custom big object. In this example, Account__c, Game_Platform__c, and Play_Date__c are part of the custom big object’s index. All rows where Account__c is “001d000000Ky3xIAB”, Game_Platform__c is “iOS”, and Play_Date__c is “2017-11-28T19:13:36.000z” are deleted.

1public static void main(String[] args) {
2    try{
3        //Declare an sObject that has the values to delete
4        sObject[] sObjectsToDelete = new sObject[1];
5        sObject[] customerBO = new sObject();
6        customerBO.setType("Customer_Interaction__b");
7        customerBO.setField("Account__c","001d000000Ky3xIAB");
8        customerBO.setField("Game_Platform__c","iOS");
9        customerBO.setField("Play_Date__c","2017-11-28T19:13:36.000z");
10        sObjectsToDelete[0] = customerBO;
11
12        DeleteByExampleResult[] result = connection.deleteByExample(sObjectsToDelete);
13    }
14}

Sample Code—Field Audit Trail

This sample shows how to delete records in FieldHistoryArchive. All rows with the specified criteria are deleted.

1public static void main(String[] args) {
2    try{
3        //Declare an sObject that has the values to delete
4        sObject[] sObjectsToDelete = new sObject[2];
5        sObject[] fieldHistoryArchive_1 = new sObject();
6        fieldHistoryArchive_1.setType("FieldHistoryArchive");
7        fieldHistoryArchive_1.setField("FieldHistoryType","Account");
8        fieldHistoryArchive_1.setField("ParentId","001d000000Ky3xIAB");
9        fieldHistoryArchive_1.setField("CreatedDate","2017-11-28T19:13:36.000z");
10        fieldHistoryArchive_1.setField("HistoryId","017D000000ESURXIA5");
11        sObjectsToDelete[0] = fieldHistoryArchive_1;
12
13        sObject[] fieldHistoryArchive_2 = new sObject();
14        fieldHistoryArchive_2.setType("FieldHistoryArchive");
15        fieldHistoryArchive_2.setField("FieldHistoryType","Account");
16        fieldHistoryArchive_2.setField("ParentId","001d000000Ky3xIAB");
17        fieldHistoryArchive_2.setField("CreatedDate","2017-11-29T19:13:36.000z");
18        fieldHistoryArchive_2.setField("HistoryId","017D000000ESURMIA5");
19        sObjectsToDelete[1] = fieldHistoryArchive_2;
20
21        DeleteByExampleResult[] result = connection.deleteByExample(sObjectsToDelete);
22    }
