Re: Convert int to hex

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.
