ROLE_ID NUMBER(10),
ROLE_NAME VARCHAR2(20))
CREATE OR REPLACE
TYPE T_RoleInfo IS TABLE OF PREORDER.
T_PREO_RoleINFO
Function F_GetUserRole(Userid in number)
return T_RoleInfo as
V_Role T_RoleInfo;
begin
     select T_PREO_RoleINFO(PREO_Role.ROLE_ID,PREO_Role.ROLE_NAME)
     BULK COLLECT INTO V_Role
     from preorder.PREO_Role, preorder.PREO_User_Role
     where PREO_Role.Role_id = PREO_User_Role.Role_id
     and PREO_User_Role.user_id = userid;
