Getting a specific key value using Corona SDK

0 votes
Can you provide example code that demonstrates how to iterate through values stored in a JSON database collection document and then, more importantly, retrieve a specific key value from that document? Thanks! Brian

Hi Brian,


You can find code snippet from here to get the document from the collection. However for retrieving a specific value from JSON object (JSON document) you can simply use below code snippet and let me know if it helps :


for i=1,table.getn(object:getJsonDocList()) do
print("DocId is "..object:getJsonDocList()[i]:getDocId())
local jsonDocument = object:getJsonDocList()[i]:getJsonDoc();
print("JSON Document is "..jsonDocument["Key name which you value you want to iterate"])

print("CreatedAt is "..object:getJsonDocList()[i]:getCreatedAt())
