I have a table in sql server which has json objects as a value in one of the columns. My requirement is to read those objects as it is and write into an index. I would like to know what are the best ways of doing it using logstash and how it can be achieved.

## eg:

## type | response

submitapi | {"abc":"xxxx","xyz":{[xxx],[xxx]}  
calcapi | {"abc":"xxxx","xyz":{[xxx],[xxx]}  
checkinapi | {"abc":"xxxx","xyz":{[xxx],[xxx]}

I need the values under response to be stored into an index **without having the 'type' column as key**.

thanks

Use the jdbc input to read from the database table. I suppose you want to parse the JSON string in the "response" column so that "abc" and "xyz" end up as separate Elasticsearch fields? Use the json filter for that.

I can use the jdbc plugin but it creates "response" as a key and value as json but i just need the value as an object.

expected in elasticsearch:  
"response":"{"abc":"xxxx","xyz":{[xxx],[xxx]}"  
required in elasticsearch:  
{"abc":"xxxx","xyz":{[xxx],[xxx]}

Thanks

Again, use the json filter.

```nohighlight
json {
  source => "response"
}

```
