How many DML statements can be executed in one transaction?
This limit increase means more than 150 DML statements can execute during a single transaction if code from the managed package and your native org both executes. Similarly, the certified managed package gets its own 100-SOQL-query limit for synchronous Apex, in addition to the org’s native code limit of 100 SOQL queries.
Is there a limit to the size of an email attachment in exchange?
Some email clients may have lower message size limits or may limit the size of an individual file attachment to a value that is less than the Exchange Online message size limit. Message header size limit: Specifies the maximum size of all message header fields in a message. The current limit is 256 KB.

What’s the maximum number of emails an Org can send per day?
Each licensed org can send single emails to a maximum of 5,000 external email addresses per day based on Greenwich Mean Time (GMT). For orgs created before Spring ’19, the daily limit is enforced only for emails sent via Apex and Salesforce APIs except for the REST API.
Can you perform two types of DML at the same time?
However, you can perform one type of DML as part of an asynchronous job and the others in other asynchronous jobs or in the original transaction. This class contains an @future method to be called by the class in the subsequent example.
When to perform DML operation on standard / Custom object?
If we perform DML operation on standard/custom object and global objects (User, UserRole, Group, GroupMember, Permission Set, etc…) in same transaction this error will come. To avoid this error, we should perform DML operation on standard/custom object records in a different transaction.
When to perform mixed DML operation in apex?
To avoid this error, we should perform DML operation on standard/custom object records in a different transaction. In general all the apex classes and apex triggers execute synchronously (execute immediately).
Why are there execution governors and limits in apex?
Execution Governors and Limits. Because Apex runs in a multitenant environment, the Apex runtime engine strictly enforces limits so that runaway Apex code or processes don’t monopolize shared resources. If some Apex code exceeds a limit, the associated governor issues a runtime exception that cannot be handled.
How to determine the execution limit of a program?
To determine the code execution limits for your code while it’s running, use the Limits methods. For example, you can use the getDMLStatements method to determine the number of DML statements that have already been called by your program.
Are there limits on how many operations can be performed in a namespace?
However, the number of operations that can be performed in each namespace must not exceed the per-transaction limits. There’s also a limit on the cumulative number of operations that can be made across namespaces in a transaction. This cumulative limit is 11 times the per-namespace limit.
How often can a DML statement be called in bulk apex?
In this example, the update statement is inefficiently called once for each opportunity. If a bulk account update operation fired the trigger, there can be many accounts. If each account has one or two opportunities, we can easily end up with over 150 opportunities. The DML statement limit is 150 calls.
Is there a limit on the number of namespaces that can be created?
There’s also a limit on the cumulative number of operations that can be made across namespaces in a transaction. This cumulative limit is 11 times the per-namespace limit.
How does a DML call outside the loop work?
The example adds the Opportunity sObject to update to a list of opportunities ( oppsToUpdate) in the loop. Next, the trigger performs the DML call outside the loop on this list after all opportunities have been added to the list. This pattern uses only one DML call regardless of the number of sObjects being updated.
