Long Text Area Field check for null

Question

What is the correct way to check if a long text area field is null/empty? Does a simple != null suffice?

if (numberApprove>0 && insuranceRecord.Comments_Private__c != null){
    sMessage = sMessage + 'Include information in the Comments field about approvals';
}

Answer 1

Long text area value is still a string so you can use standard string functions. Try this:

if (numberApprove>0 && String.isBlank(insuranceRecord.Comments_Private__c)){
    sMessage = sMessage + 'Include information in the Comments field about approvals';
}

If you want to check whether it is not blank, then use String.isNotBlank(insuranceRecord.Comments_Private__c)
