System.StringException: Ending position out of bounds:

Question

I am getting the titled error

System.StringException: Ending position out of bounds:99

for the below code:

CusObj2.ProdName__c=CusObj2.Name__c.substring(0,99);

All I want to do is truncate the name in this trigger to 99 characters or fewer. Please advise.

Pls note I am getting this error only when deploying a change set - it passes the same testClass in my sandbox.

Answer 1

The abbreviate method is a good choice:

CusObj2.ProdName__c = CusObj2.Name__c.abbrevate(99);

as it:

Returns an abbreviated version of the String, of the specified length and with ellipses appended if the current String is longer than the specified length; otherwise, returns the original String without ellipses.

where ellipses means three dots.

PS

Or if Name__c can be null:

CusObj2.ProdName__c = CusObj2.Name__c != null ? CusObj2.Name__c.abbrevate(99) : null;
