Returning null fields

[lamuzzachiodi]

When i recover nullable fields (i'm working in mysql, btw) in a form for update, i get the string "null".
May be there are a context where this way is useful, but it seem no practical in general (at least when you are updating data and you want recover and also save this data as is).
I guess that recovering as an empty string could be a better way. So, i suggest add the option to get null fields as empty strings.

Same here... using PHP 7.3

datatype: text
allow null
default value: null

I'm confused when try to validating null value:

// after init medoo
$result = $database->get("mytable", "myfield_thats_null", ["id" => 1]);

some times result was NULL but sometimes will becomes "null" (string)

Forget my reply above, I found null string comes from 3rd party json result that not proper set null:

"value": "null"  instead "value":null

I believe it doesn't make sense bacause the Medoo is PDO based, its a default behaviour of PDO.

if you use Oracle you can pass this attibutes in your options of Medoo connection:

	PDO::ATTR_ORACLE_NULLS => PDO::NULL_TO_STRING
