Sharing Mode

Control how DML operations respect record-level sharing rules.

Example

System.runAs(minimalAccessUser) {
    new DML()
        .toUpdate(contact)
        .systemMode()
        .withSharing()
        .commitWork();
}

Use Cases

Administrative Operations

When performing admin-level operations that should bypass sharing:

public class DataMigrationService {
    public void migrateRecords(List<Account> accounts) {
        new DML()
            .toUpdate(accounts)
            .systemMode()
            .withoutSharing()
            .commitWork();
    }
}

We suggest using .systemMode().withoutSharing() in triggers, as trigger logic should always be executed.

withSharing

By default, the DML library uses with sharing, meaning it respects the sharing context of the calling class. Sharing mode is enforced by userMode(), which is the default mode. Only when .systemMode() is used, .withSharing() can control the sharing mode.

Execute DML operations enforcing sharing rules. Records the user doesn't have access to will cause errors.

Signature

Committable withSharing();

Standard DML

// In a "with sharing" class context
public with sharing class MyClass {
    public void updateRecord(Contact contact) {
        update contact; // Sharing rules enforced
    }
}

DML Lib

new DML()
    .toUpdate(contact)
    .systemMode()
    .withSharing()
    .commitWork();

withoutSharing

Execute DML operations bypassing sharing rules. All records are accessible regardless of sharing settings. To use .withoutSharing(), the .systemMode() must be enabled.

Signature

Committable withoutSharing();

Standard DML

// In a "without sharing" class context
public without sharing class MyClass {
    public void updateRecord(Contact contact) {
        update contact; // Sharing rules bypassed
    }
}

DML Lib

new DML()
    .toUpdate(contact)
    .systemMode()
    .withoutSharing()
    .commitWork();
