    What is the advantage of using Database Class over Statement Method to execute DML?

    Use DML statements if you want any error that occurs during bulk DML processing to be thrown as an Apex exception that immediately interrupts control flow (by using try. . .catch blocks). This behavior is similar to the way exceptions are handled in most database procedural languages.

    Use Database class methods if you want to allow partial success of a bulk DML operation—if a record fails, the remainder of the DML operation can still succeed. Your application can then inspect the rejected records and possibly retry the operation. When using this form, you can write code that never throws DML exception errors. Instead, your code can use the appropriate results array to judge success or failure. Note that Database methods also include a syntax that supports thrown exceptions, similar to DML statements.

    Hi,

    Because the Database class provides methods not available as DML statements, such as methods transaction control and rollback, emptying the Recycle Bin, and methods related to SOQL queries.

    Thanks.

    Hi,

    Apex offers two ways to perform DML operations: using DML statements or Database class methods. This provides flexibility in how you perform data operations. DML statements are more straightforward to use and result in exceptions that you can handle in your code.

    One difference between the two options is that by using the Database class method, you can specify whether or not to allow for partial record processing if errors are encountered. You can do so by passing an additional second Boolean parameter. If you specify false for this parameter and if a record fails, the remainder of DML operations can still succeed. Also, instead of exceptions, a result object array (or one result object if only one sObject was passed in) is returned containing the status of each operation and any errors encountered. By default, this optional parameter is true, which means that if at least one sObject can’t be processed, all remaining sObjects won’t and an exception will be thrown for the record that causes a failure.

    The following helps you decide when you want to use DML statements or Database class methods.

    Hope this helps!
