Dear Members!A web developer stores JSON like strings in a text column.With E prefix we can get the real text:Select E'Az ad\u00f3kulcsonk\u00e9nti'Hungarian: "Az adókulcsonkénti" (ISO-8859-2)How to get the same result from a table column?select WhatAFunction( ATable.JSONLikeTextColumn) from ATableWhat function do we need to use to "simulate" E prefix?
Currently there are not any functions that you need. You need to write your own.
CREATE OR REPLACE FUNCTION public.unistr(text)
RETURNS text
LANGUAGE plpgsql
IMMUTABLE STRICT
AS $function$
declare r text;
begin
execute 'select e''' || $1 || '''' into r;
return r;
end;
$function$;
RETURNS text
LANGUAGE plpgsql
IMMUTABLE STRICT
AS $function$
declare r text;
begin
execute 'select e''' || $1 || '''' into r;
return r;
end;
$function$;
Attention: This is ugly and possible sql injection vulnerable!!! But there is not another way. The fix is in queue
