When running sql script to view data on Cexplorer database, many times,I see binary data. for example, multi_asset.name, multi_asset.policy in the following query.

enter image description here

Is there any way to view these data in normal text?

Thanks very much.

These fields are not in general "normal text". They might be normal text (eg ASCII) or they could also be UTF-8 or UTF-16 or any other encoding.

The most sensible way to view them is as hexadecimal and that is what the psql command line does. Eg:

$ psql cexplorer
psql (14.5 (Debian 14.5-1), server 13.7 (Debian 13.7-0+deb11u1))
Type "help" for help.

cexplorer=# select * from multi_asset limit 1 ; 
 id |                           policy                           |       name       |                 fingerprint                  
  1 | \x00000002df633853f6a47465c9496721d2d5b1291b8398016c0e87ae | \x6e7574636f696e | asset12h3p5l3nd5y26lr22am7y7ga3vxghkhf57zkhd
(1 row)

So it you want something that is guaranteed to be "normal text" you should use the fingerprint field, which is Bech32 encoded.

  • Thank you very much. Is there anyway to do like this on PgAmin?

in your case:

SELECT multi_asset.policy::text human_policy FROM ...


SELECT encode(multi_asset.name::bytea, 'escape'::text) human_name FROM ... 
  • thanks a lot. For me, it is the easiest way.
