Hi all,

I was working with facebook apps and sapphire and normal Int field out of space.

Question how make ID type bigint auto increament.

I traced mysqldatabyse class added new function

       public function bigint($values){
		//For reference, this is what typically gets passed to this function:
		//$parts=Array('datatype'=>'int', 'precision'=>11, 'null'=>'not null', 'default'=>(int)$this->default);
		//DB::requireField($this->tableName, $this->name, "int(11) not null default '{$this->defaultVal}'");

		return 'bigint(26) not null auto_increment';
	}

and created bigint class

class BigInt extends DBField {

	function __construct($name, $defaultVal = 0) {
		$this->defaultVal = is_int($defaultVal) ? $defaultVal : 0;
		
		parent::__construct($name);
	}

	/**
	 * Returns the number, with commas added as appropriate, eg “1,000”.
	 */
	function Formatted() {
		return number_format($this->value);
	}

	function nullValue() {
		return "0";
	}

	function requireField() {
		$parts=Array('datatype'=>'bigint', 'precision'=>26, 'null'=>'not null', 'default'=>$this->defaultVal, 'arrayValue'=>$this->arrayValue);
		$values=Array('type'=>'bigint', 'parts'=>$parts);
		DB::requireField($this->tableName, $this->name, $values);
	}

	function Times() {
		$output = new DataObjectSet();
		for( $i = 0; $i < $this->value; $i++ )
			$output->push( new ArrayData( array( 'Number' => $i + 1 ) ) );

		return $output;
	}

	function Nice() {
		return sprintf( '%d', $this->value );
	}
	
	public function scaffoldFormField($title = null, $params = null) {
		return new NumericField($this->name, $title);
	}
	
	/**
	 * Return an encoding of the given value suitable for inclusion in a SQL statement.
	 * If necessary, this should include quotes.
	 */
	function prepValueForDB($value) {
		if($value === true) {
			return 1;
		} if(!$value || !is_numeric($value)) {
			if(strpos($value, '[')===false)
				return '0';
			else
				return addslashes($value);
		} else {
			return addslashes($value);
		}
	}
	
}

But problem is when i run DB build in dataobject overloading ID => 'BigInt' its goes some complicated.

Maybe some had intructions? :)

P.S. sorry for my English.

I am using SS 2.4.3

It is probably not a good idea to try to hack around with the ID field.

Any particular reason you can't just create a new field? Then you could just use a text field, or your custom BIGINT.

Its not secret I wanna extend Dataobject Member Class, Like Player, and use Facebook users ID, save like member table ID.

I was buld how I sad "mysqlDatabese" class changes its works, but not allways as I think. Some times when building (dev/build) DB , Its randomly Alter tables ID types from bitint (I made self) and default INT (11) And backward.

I dont understand DB compilling algorythm (need more research).
I feel its problem somever when I overload member ID and Player ID to big int...

Yeah dam, I'm jsut going through the same issue. Will opt to use Varchar for the meantime. A bigint option would be nicer.

Just a point about Bigint and Facebook id's, Bigint's by themselves are 63 bit, they need to be UNSIGNED to match Facebook's 64 bit ID's.
