Structure a json out of data from a table
I have a table with data like so:
a
b
c
d
e
f
..so on till Z
now I need to load this into a JSON and I'm really really confused as to how it will be .
will it be
{"rec":{"character":"a"}, "rec":{"ch开发者_如何转开发aracter":"b"}}
or should it all be within an array (this doesn't make sense to me) ?
I'm really new to JSON and would really appreciate some quick help.
For a complicated table: The "correct" approach depends on what the data actually means. You could use arrays for the key-values:
{"a":[1,2,3], "b":[4,5,6], etc.}
However, it's often better to use sub-keys. For instance, say I have a database table like:
RECORD FIRST LAST BIRTHYEAR
1 Sam Spade 1977
2 Jane Tarzan 1945
3 Billy Boinger 1984
To convert the whole table into JSON, I might do:
{
1: {
"first":"Sam",
"last":"Spade",
"birthyear":1977
},
2: {
"first":"Jane",
"last":"Tarzan",
"birthyear":1945
},
3: {
"first":"Billy",
"last":"Boinger",
"birthyear":1984
}
}
You can see how that is not only more readable, but it makes it easier to access precisely the data you need.
If these are values from a select query, I would think you can do it using a JSONArray
. Its string structure would look like this:
["a","b","c",...,"x","y","z"]
It currently cannot be what you have listed, as your (top level) JSONObject
contains two of the same key "rec".
