Other than doing string manipulation after each JSON_EXTRACT, is there a simpler or more correct way to have the JSON_EXTRACT return the string WITHOUT the enclosing quotes?

Or should this question be on StachExchange?

  • Did you put an extra pair of quotes on the string as it was inserted?? – Rick James Jul 15 '16 at 2:26
  • The JSON from the REST call is a simple: {"key": "value to return" } Looks like the only way is to do a TRIM(BOTH " variable) <something like that ;) > – Hvisage Jul 15 '16 at 8:20

If you have MySQL 5.7.13 or later, you may use JSON_UNQUOTE() instead of JSON_EXTRACT() or ->> instead of ->. Example:

SELECT field->>"$.foo.barr" FROM table;

I can't comment on Alex Markov's answer because I don't have enough reputation. In my case using JSON_UNQUOTE instead of JSON_EXTRACT doesn't work, but I can get the result by wrapping the second inside the former, like this: JSON_UNQUOTE(JSON_EXTRACT(bla bla))
