I want to be able to change an int4 from a sequence and store it as
varchar in the database as a hex number.
Is this possible?
Thank you,
Fernando

Try the to_hex() function - in the "Functions and operators" chapter of
the manual - "Strings" section.

Thank you, I found out after I posted the message.
I did read the docs but must have looked somewhere else and I search
the lists for hex only and it did not bring the answer back. It
wasn't until I search for int4 to hex that I was able to find the
answer.
Thank you again.

Hi,
You can use to_hex() function to convert integer to hexa number. I have tried with a small example.
create table testing( id int4 , sHex varchar( 20 ) )
insert into testing( id ) values( 204678 );
insert into testing( id ) values( 2076876 );
update testing set sHex = ( cast( to_hex( id ) as varchar( 20 ) ) )
select * from testing
Id | shex
-------|------
204678 | 31f86
2076876| 1fb0cc
Regards,
R.Muralidharan
