Re: How to use JSON in MonetDB

Hi, The most likely reason is that you are using an older version. I did not check when this became part of our distribution. If you build it from source, you certainly will get this. Arjen ----- Original Message -----

Hi Art,

JSON is a column type, so you first need to define a table with a column of type JSON, something like:

CREATE TABLE A (js JSON);

Once you inserted json documents into the table, you can do a query like:

select json.filter(js, 'store') from js;

Hello! MonetDB documentation says, that JSON is supported in MonetDB, but I can`t find any example. When I try to implement this query in MonetDB client: json . filter ({ "store" : { "bicycle" : { "color" : "red" , "price" : 19.95 }}}, '$' )

I get this error: syntax error, unexpected IDENT in: "json"
