Hi All,
I'm trying to create an array of JSON objects from an existing table.
I've created a new table:
"CREATE TABLE json(data json[]);"
Now i need to populate it with key value pairs from another table. I'd
like to create the objects to look like:
{ "code": rawdata.deptcode, "name": rawdata.deptname }
But I'm having difficulty understanding the syntax to do this because I
find the docs to be rather difficult to parse.
I've tried running the query:
"INSERT INTO json(data) json_build_object(SELECT DISTINCT deptcode,
deptname AS code, name FROM rawdata);"
but it returns a syntax error.
That would be?
What version of Postgres?
I've also tried running:
"INSERT INTO json(data) row_to_json(SELECT DISTINCT deptcode, deptname
FROM rawdata);"
but no dice.
Does anyone know the proper syntax to create an array of JSON objects
from an existing table?
json_build_array?
