Hi all,
How DAL is supported json query?
My test is on Web2py by source code v.2.10.3, PostgreSQL 9.4:
db.define_table('person',
Field('name','string'),
Field('jdata','json'))
db.person.insert(name='Adam',jdata='{"age":30}')
print db.executesql('SELECT * FROM person WHERE (jdata ->> "age") > "20";')
I get this error:
Traceback (most recent call last):
