APEX

Can someone help me please I am building an application based on a user table I have created in my schema but I do not want to use
wwv_flow_custom_auth_std.login(
P_UNAME => v('P1_USERNAME'),
P_PASSWORD => :P1_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':2'
);
I would like to create a stored based on the user like
obj_login(P_USERNAME => :P1_USERNAME,
P_PASSWORD => :P1_PASSWORD,
P_SESSION_ID => v('APP_SESSION'),
P_FLOW_PAGE => :APP_ID||':2'
);
Because after login I will like to send them to a page based on another role table I have created.

Please help it is urgent
