Re: json conditional arrays/objects

Actually I have to confess that in this instance I can't. DATA-GEN has a
similar issue in that, although it will not output empty array entries, it
still outputs the object itself with an empty array.

Probably should write up an IDEA on that as it should be possible to fix
without too much of a problem.

Ok I asked a question about this last week and got a good answer back

from

Birgitta but I've cleaned my gmail up and cannot find that last post
unfortunately, so starting a new one...

Lets say I have the following json structure embedded in another json
object...

"Array1": [
{
"key1": "myValue1",
"key2": "myValue2",
"Array2": [
{
"key3": "myValue3",
"key4": "myValue4"
}
]
},
{
"key5": "myValue5",
"key6": "myValue6"
}
]

But I only want that array or object to show if non-blanks are passed

to

any of "myValues"
and I cannot have empty structures such as {}.

Is there a way to do this with db2 sql json functions?

I used Birgittas instructions on a field basis using syntax such as...

values json_object('key1"
:case when :myValue <> ' '
then trim(:myValue)
end
absent on null);

But this will leave {} if nothing in myValue.
How do I ensure it does not build the empty structure?

tia
