Storing an IP Address in a Oracle SQL Table [duplicate]

Answer 1

Try storing the value as a string and using quotes:

CREATE TABLE ipdetails( ip_address varchar(15) NOT NULL, vlan_id varchar(50) );

and then . . .

INSERT INTO ipdetails VALUES ('192.169.698.365', 'Sample1')

You might want to store each component in a separate field.

Answer 2

You have several options:

• Store it as a VARCHAR. IP address isn't really a number you're likely to do math on, so why store it in numeric format?
• Store it in hexidecimal as a single number. While you can't really do that in decimal, in hexidecimal an IP is an 8 digit number.
• Store it as (up to) four separate fields. Probably unnecessary but for certain applications (where you might want to primarily only be concerned with one part of the IP) this could be useful.

Answer 3

You can store an IP as a number, that is how they exist internally, but you will have to write code to convert back and forth:

#include <arpa/inet.h>
/* 
 * Returns a pointer to an internal array containing the string, which is overwritten with each call to the function.
 * You need to copy the string if you want to keep the value returned.
 */
extern char *inet_ntoa (struct in_addr in);

/* 
 * Convert Internet host address from numbers-and-dots notation in CP
 * into binary data and store the result in the structure inp.
 */
extern int inet_aton (const char *cp, struct in_addr *inp);

Here is some simple SQL that does what one of these do ip->decimal , using 127.0.0.1

SELECT
TO_NUMBER(REGEXP_SUBSTR('127.0.0.1','\w+',1,1))*POWER(2,24)
+ TO_NUMBER(REGEXP_SUBSTR('127.0.0.1','\w+',1,2))*POWER(2,16)
+ TO_NUMBER(REGEXP_SUBSTR('127.0.0.1','\w+',1,3))*POWER(2,8)
+ TO_NUMBER(REGEXP_SUBSTR('127.0.0.1','\w+',1,4))*POWER(2,0) IP
FROM
DUAL;
