I have a laravel web application that is nearly completed. I have had to switch database servers and have run into an unexpected problem. The new database does not allow null values. Other applications read and write to this database which is why nulls are not allowed. Therefore I will not be able to change the database. What would be the easiest way to check for null values before a save?

I think you might want to set up a test of this.  When tables are created by CREATE TABLE the column definitions can be set to NOT NULL and can be set to contain a DEFAULT value.  When your script INSERTs data into a row, any columns that are not included are given their default value.  If you INSERT an empty string into a NOT NULL column, the data base will keep it and will return an empty string to the SELECT queries.

So you may be OK right now, assuming that the database tables are defined correctly.

The solution was to setup mutators in the model. even though the column name was in snake case I still had to use camel case for the function name. so SALES_ORDER_NUMBER became SalesOrderNumber. here is an example:

protected function getSalesOrderNumberAttribute($value) { return $this->attributes['SALES_ORDER_NUMBER']; }
protected function setSalesOrderNumberAttribute($value) { $this->attributes['SALES_ORDER_NUMBER'] = (is_null($value) ? '' : $value); }

found the answer in the laravel docs that did not force me to change the database.
