问题 Good evening to everybody here! At this moment I'm working with one page in Oracle Apex (version 4.2.6.00.03).

问题 I have a stored procedure that has a SYS_REFCURSOR as an OUT parameter. The signature is, for example, as follows: PROCEDURE myProc(p_someID IN INTEGER, p_cursor OUT SYS_REFCURSOR); I call this procedure from a function, where I have to copy a column named clientID from the p_cursor to a scalar nested table. I am doing as follows: CREATE OR REPLACE FUNCTION myFunction RETURN sys_refcursor IS someID INTEGER := 1234; myCursor SYS_REFCURSOR; TYPE t_clientID_nt IS TABLE OF NUMBER(16,0); clientID

My source IP address is dotted notation such as 127.0.0.1 and the table has two fields stored as integers such as 2130706433. So I need to convert the dotted notation to the integer in my where clause like this; select get_ip_integer('74.253.103.98') ,icb.*,icl.* from ip_city_block icb, ip_city_location icl where get_ip_integer('74.253.103.98') between icb.startipnum and icb.endipnum and icl.locid
