PL SQL Apex_JSON - Parse element name - plsql

Question

I am trying to get the value from the following array -
{
"list:" [
{
"User.name":"AAA"
},
{
"User.Name":"BBB"
}
]
}
I tried to get the Name value but I got null -
for i in 1..Apex_Json.get_count('list') loop
l_name := Apex_Json.Get_varchar2('list[%d].User.Name', i);
end loop;
How can I get the name value?

"list" is json array of elements. AFAIK you can't access an element directly but you can loop through the array to check if an element with a specific name exists. Here is an example:
DECLARE
l_json_text VARCHAR2(4000);
l_json_values apex_json.t_values;
l_name VARCHAR2(4000);
BEGIN
l_json_text := q'!
{
"list": [
{
"User.name":"AAA"
},
{
"User.Name":"BBB"
}
]
}
!';
apex_json.parse(
p_values => l_json_values,
p_source => l_json_text
);
-- get nr of elements in the array and loop through it.
FOR r IN 1 .. APEX_JSON.get_count(p_path => 'list', p_values => l_json_values) LOOP
-- get the value for User.Name for this array index.
-- If it is doesn't exist it will be NULL
l_name := apex_json.get_varchar2(p_path => 'list[%d]."User.name"', p0 => r, p_values => l_json_values);
IF l_name IS NOT NULL THEN
DBMS_OUTPUT.put_line('"User.name":'||l_name);
END IF;
END LOOP;
END;
/
Note that there is a typo in your question json: "list:" [ should be "list": [
