I have 3 variables, street and neighborhood that are required and can be null zip, zip comes up other than null the query below works, but if it comes null zip it does not work, how do I work if the zip is null?
In your db, is there a good reason for zip to not be null? If not, allow null values. If so, fix your applications so that null values can't be sent to your db.
Oh, by the way, I'm sure you know the old saying. You have your mandatory fields, I have my default values.

Step back from your code and think.
