Обсуждение: Maximum limit on int in plpgsql

Hello,

I am passing the ip address as a varchar. Eg: 133.9.4.11

Later on i am splitting the ip address with the delimiter as '.'


ip1t:= split_part($1,'.',1); // returns a text value
ip2t:= split_part($1,'.',2); // returns a text value
ip3t:= split_part($1,'.',3);
ip4t:= split_part($1,'.',4);

Then i am type casting it into an integer

select into ip1 cast(ip1t as integer);
select into ip2 cast(ip2t as integer);
select into ip3 cast(ip3t as integer);
select into ip4 cast(ip4t as integer);

The i am taking the sum using this formula

out_sum=ip1*256*256*256+ip2*256*256+ip3*256+ip4;

When i run the procedure i am getting following error
pg_atoi : Numerical result out of range

I tried all possible datatypes but still i am getting the same error.

Is it the problem of typecasting or the limits on datatype?

Thank you in advance,
deepthi

This question has nothing to do with JDBC or Java and is not appropriate
for this list.  Please try pgsql-general@postgresql.org for this type of
question.

Hi !

pg_atoi sounds like a function that converts from a string to an integer so
the problem would be with the cast in that case, even though I cannot see
any problem with your example.
