You can also use future methods to isolate DML operations on different sObject types to prevent the mixed DML error. Each future method is queued and executes when system resources become available. That way, the execution of your code doesn’t have to wait for the completion of a long-running operation. A benefit of using future methods is that some governor limits are higher, such as SOQL query limits and heap size limits. You can call 50 future methods per transaction. Things to Remember: Methods are annotated with  @future  annotation. Use the future annotation to specify that th...

The merge statement merges up to three records...
