You are sure, the string always has this format?
Then there is a solution, though an external method might be better:
<dtml-let result=sql_method
strip_outer_chars="result[3:-3]"
split="_.string.split(strip_outer_chars,'\x22},{\x22')"
rejoin="_.string.join(split,',')"
>
<dtml-var rejoin> <!-- your a,b,c -->
</dtml-let>
