Read Write inside data base

[Andrej]

I'm struggling with database how can i get value from custom column.
I have create a custom column "Start" inside "character_data" with:
 

ALTER TABLE `Character_DATA` ADD `Start` INT(1) NOT NULL DEFAULT '1';

I have tried with:
 

_key = format["CHILD:999:SELECT `Start` FROM `charater_data`"];
_data = _key call server_hiveReadWrite;

I need that INT from "Start"  "1" to select don't know how
and i need update it don't know how i tried with

_key = format["CHILD:998:UPDATE `character_data` SET `Start`= 2"];
_result = _key call server_hiveReadWrite; 

Please someone help cant make this working.
Thank you
