Add ing register to static realtime database

Hi, using asterisk I am storing my sip.conf stuff in a database rather than in a text
file. So i have static realtime setup. I understand how to use the ast_config table ot enter
normal entries into the database but how about the register => statment. i want to add
some of these, how to do this

register =>

INSERT INTO ast_config (cat_metric , var_metric , filename , category , var_name , var_val ) VALUES (‘0’,‘0’,‘sip.conf’, ‘general’, ‘register’, ’’);

Would you still do it like above, was wondering becaue of the differnt syntax , normal value have an ‘=’ the
register statement has ‘=>’
