First post here at PostgreSQL; please forgive any etiquette mistakes… I have a query that extracts a field from a JSONB column, e.g.:
SELECT (((mytable.ajsonbcolumn -> ‘somedata’) -> ‘nested’) ->> ‘first_name’) AS fname FROM mytable When I save it into a view, PostgreSQL transforms it thusly: SELECT (((mytable.ajsonbcolumn -> ‘somedata’::text) -> ‘nested’::text) ->> ‘first_name’::text) AS fname FROM mytable (note the ::text casts). Why does it do this? It seems unnecessary and pollutes my SQL with a ton of extra text. Thanks for your thoughts. -Ben ******************* PLEASE NOTE ******************* This E-Mail/telefax message and any documents accompanying this transmission may contain information that is privileged, confidential, and/or exempt from disclosure under applicable law and is intended solely for the addressee(s) named above.
