如何排序IPv4和IPv6 1列内解决

我要排序的IPv4如何排序IPv4和IPv6 1列内解决

order by (to_number(substr(ipcidr,1,instr(ipcidr,'.')-1)) 
, to_number(substr(ipcidr,instr(ipcidr,'.')+1, instr(ipcidr,'.',1,2) - instr(ipcidr,'.') - 1)) 
, to_number(substr(ipcidr,instr(ipcidr,'.',1,2)+1, instr(ipcidr,'.',1,3) - instr(ipcidr,'.',1,2) - 1)) 
, to_number(substr(ipcidr,instr(ipcidr,'.',1,3)+1,instr(ipcidr,'/')-instr(ipcidr,'.',1,3) - 1)) 
, to_number(substr(ipcidr,instr(ipcidr,'/')+1)))

，并在一个科拉姆排序IPv6和我有FLAG_V6列在IPv6设定1，否则空

你可以使用此功能将IP地址转换为整数：

-- Convert a binary/octal/hex number into a decimal value 
CREATE FUNCTION Base2Dec(BaseString IN VARCHAR2, Base IN PLS_INTEGER DEFAULT 16) RETURN NUMBER DETERMINISTIC IS 

    BaseNumber NUMBER := 0; 
    HexString CONSTANT CHAR(16) := 'ABCDEF'; 

BEGIN 
    IF BaseString IS NULL THEN 
     RETURN NULL; 
    ELSIF Base NOT IN (2, 8, 16) THEN 
     RAISE VALUE_ERROR; 
    ELSIF Base = 16 THEN 
     RETURN TO_NUMBER(BaseString, 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'); 
    ELSE 
     FOR i IN 1..LENGTH(BaseString) LOOP 
      BaseNumber := BaseNumber * Base + INSTR(HexString, UPPER(SUBSTR(BaseString, i, 1))) - 1; 
     END LOOP; 
     RETURN BaseNumber; 
    END IF; 
END Base2Dec; 

CREATE FUNCTION UncompressIpV6(Ip IN VARCHAR2) RETURN VARCHAR2 DETERMINISTIC IS 
    IpFull VARCHAR2(40); 
BEGIN 
    IF REGEXP_LIKE(Ip, '::') THEN 
     IpFull := REGEXP_REPLACE(REGEXP_REPLACE(Ip, '^::', '0::'), '::$', '::0'); 
     WHILE REGEXP_COUNT(IpFull, ':') <= 7 LOOP 
      IpFull := REGEXP_REPLACE(IpFull, '::', ':0::'); 
     END LOOP; 
     RETURN REGEXP_REPLACE(IpFull, '::', ':'); 
    ELSE 
     RETURN Ip; 
    END IF; 
END UncompressIpV6; 

CREATE FUNCTION Ip2Decimal(IP IN VARCHAR2) RETURN NUMBER DETERMINISTIC IS 
    DecimalIp NUMBER := 0; 
BEGIN 

    IF REGEXP_LIKE(IP, ':') THEN 
     SELECT SUM(Base2Dec(REGEXP_SUBSTR(UncompressIpV6(IP), '[[:xdigit:]]+', 1, LEVEL), BASE_HEX) * POWER(65536, 8-LEVEL)) 
     INTO DecimalIp 
     FROM dual 
     CONNECT BY LEVEL <= 8; 
     RETURN DecimalIp;  
    ELSE 
     SELECT SUM(REGEXP_SUBSTR(IP, '\d+', 1, LEVEL) * POWER(256, 4-LEVEL)) 
     INTO DecimalIp 
     FROM dual 
     CONNECT BY LEVEL <= 4; 
     RETURN DecimalIp; 
    END IF; 

END Ip2Decimal;

它适用于IPv4和IPv6。它只应用于IPv4，应该是非常明显的。 IPv6工作。

您可以在您的订单使用它BY子句：

ORDER BY FLAG_V6 NULLS FIRST, Ip2Decimal(IPCIDR)

谢谢。没关系，我想在PHP中应用这个命令调用函数 –
