# Select Queries
Select queries return raw Druid rows and support pagination.

```json
 {
   "queryType": "select",
   "dataSource": "wikipedia",
   "dimensions":[],
   "metrics":[],
   "granularity": "all",
   "intervals": [
     "2013-01-01/2013-01-02"
   ],
   "pagingSpec":{"pagingIdentifiers": {}, "threshold":5}
 }
```

There are several main parts to a select query:

|property|description|required?|
|--------|-----------|---------|
|queryType|This String should always be "select"; this is the first thing Druid looks at to figure out how to interpret the query|yes|
|dataSource|A String defining the data source to query, very similar to a table in a relational database|yes|
|intervals|A JSON Object representing ISO-8601 Intervals. This defines the time ranges to run the query over.|yes|
|filter|See [Filters](Filters.html)|no|
|dimensions|The list of dimensions to select. If left empty, all dimensions are returned.|no|
|metrics|The list of metrics to select. If left empty, all metrics are returned.|no|
|pagingSpec|A JSON object indicating offsets into different scanned segments. Select query results will return a pagingSpec that can be reused for pagination.|yes|
|context|An additional JSON Object which can be used to specify certain flags.|no|

The format of the result is:

```json

  "timestamp" : "2013-01-01T00:00:00.000Z",

    "pagingIdentifiers" : {

        "user" : "MZMcBride",
        "count" : 1.0,
        "added" : 68.0,
        "delta" : 68.0,
        "variation" : 68.0,
        "deleted" : 0.0
      }
    } ]
  }
} ]
```

The result returns a global pagingSpec that can be reused for the next select query. The offset will need to be increased by 1 on the client side.
