In the below example, I'm changing centerID and typeID to have also 'UNSIGNED' attributes right?

Field  	         Type  	        Attributes  	Null  	Default  	Extra  	Action
resourceID  	int(11)  	UNSIGNED  	No  	 	        auto_increment
centerID  	int(11)  	  	        Yes  	NULL  	
typeID  	int(11)  	  	        Yes  	NULL
