Question

This works:

SELECT DISTINCT HEX(group_uuid) AS hexid 
FROM schema.table

>9B3D8DE01E1E049DA9F17D42B324AA66
>CDF112D740CE14EA08CA90E3C937DE8D

as does this

SELECT  GROUP_CONCAT('\'', HEX(group_uuid), '\' ') AS hexid 
FROM schema.table

>'9B3D8DE01E1E049DA9F17D42B324AA66','9B3D8DE01E1E049DA9F17D42B324AA66' [etc...]

and this

SELECT  GROUP_CONCAT(DISTINCT HEX(group_uuid) SEPARATOR '\' ') AS hexid 
FROM schema.table

>9B3D8DE01E1E049DA9F17D42B324AA66' CDF112D740CE14EA08CA90E3C937DE8D

this, however,

SELECT  GROUP_CONCAT('\'', DISTINCT HEX(group_uuid), '\' ') AS hexid 
FROM schema.table 

Error Code: 1064. You have an error in your SQL syntax; INSERT COIN

does not.

Is there some kind ‘PREFIX’ keyword that can be substituted or another syntax I’m supposed to follow?

Answer 1

Are you looking for

 GROUP_CONCAT(DISTINCT CONCAT('\'',HEX(group_uuid),'\'') SEPARATOR ' ')
