Bom dia a todos.
Em certa tabela, tenho um campo jsonb que contem o seguinte array:
[{"usuario":"pedrobase","data":"08\/10\/2018
14:02:34","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:38","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:38","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:39","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:39","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:48","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:49","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:49","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:49","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:49","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:49","comentario":""},{"usuario":"pedrobase","data":"08\/10\/2018
14:02:50","comentario":""}]
Preciso explodí-lo em um recordset como este:
usuario |data |comentario
----------+-------------------+----------
pedrobase |08/10/2018 14:02:34|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:38|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:38|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:39|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:39|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:48|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:49|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:49|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:49|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:49|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:49|
----------+-------------------+----------
pedrobase |08/10/2018 14:02:50|
Em uma consulta à documentação [
https://www.postgresql.org/docs/current/static/functions-json.html] não
encontrei nada que realmente me ajudasse nesta questão.
Qual a melhor forma de obter o resultado demonstrado no exemplo?
