Trying to wrap my head around postgresql 9.4 jsonb and would like some help
figuring out how to do the following.
Given the following example jsonb:
‘{“name1” : value1, “name2” : value2, “name3” : [int1, int2, int3]
}’::jsonb AS table1.column1
Wanted: Return the “name3” array only, as a table with a return signature of
TABLE( var_name varchar, var_value int, var_row_num int)
So the resulting data would look like this:
(‘name3’, int1, 1)
(‘name3’, int2, 2)
(‘name3’, int3, 3)
Assume the array could be any length except zero and ‘name3’ is guaranteed to
exist.
