:::info
 Apache Druid supports two query languages: Druid SQL and [native queries](../querying/querying.md).
 This document describes the SQL language.
:::

In this topic, `http://ROUTER_IP:ROUTER_PORT` is a placeholder for your Router service address and port. Replace it with the information for your deployment. For example, use `http://localhost:8888` for quickstart deployments.

## Query from Historicals

### Submit a query

Submits a SQL-based query in the JSON request body. Returns a JSON object with the query results and optional metadata for the results. You can also use this endpoint to query [metadata tables](../querying/sql-metadata-tables.md).

Each query has an associated SQL query ID. You can set this ID manually using the SQL context parameter `sqlQueryId`. If not set, Druid automatically generates `sqlQueryId` and returns it in the response header for `X-Druid-SQL-Query-Id`. Note that you need the `sqlQueryId` to [cancel a query](#cancel-a-query).

#### URL

`POST` `/druid/v2/sql`

#### Request body

The request body takes the following properties:

* `query`: SQL query string.

* `resultFormat`: String that indicates the format to return query results. Select one of the following formats:
  * `object`: Returns a JSON array of JSON objects with the HTTP response header `Content-Type: application/json`.  
     Object field names match the columns returned by the SQL query in the same order as the SQL query.

  * `array`: Returns a JSON array of JSON arrays with the HTTP response header `Content-Type: application/json`.  
     Each inner array has elements matching the columns returned by the SQL query, in order.

  * `objectLines`: Returns newline-delimited JSON objects with the HTTP response header `Content-Type: text/plain`.  
     Newline separation facilitates parsing the entire response set as a stream if you don't have a streaming JSON parser.
     This format includes a single trailing newline character so you can detect a truncated response.

  * `arrayLines`: Returns newline-delimited JSON arrays with the HTTP response header `Content-Type: text/plain`.  
     Newline separation facilitates parsing the entire response set as a stream if you don't have a streaming JSON parser.
     This format includes a single trailing newline character so you can detect a truncated response.

  * `csv`: Returns comma-separated values with one row per line. Sent with the HTTP response header `Content-Type: text/csv`.  
     Druid uses double quotes to escape individual field values. For example, a value with a comma returns `"A,B"`.
     If the field value contains a double quote character, Druid escapes it with a second double quote character.
     For example, `foo"bar` becomes `foo""bar`.
      This format includes a single trailing newline character so you can detect a truncated response.

* `header`: Boolean value that determines whether to return information on column names. When set to `true`, Druid returns the column names as the first row of the results. To also get information on the column types, set `typesHeader` or `sqlTypesHeader` to `true`. For a comparative overview of data formats and configurations for the header, see the [Query output format](#query-output-format) table.

* `typesHeader`: Adds Druid runtime type information in the header. Requires `header` to be set to `true`. Complex types, like sketches, will be reported as `COMPLEX<typeName>` if a particular complex type name is known for that field, or as `COMPLEX` if the particular type name is unknown or mixed.

* `sqlTypesHeader`: Adds SQL type information in the header. Requires `header` to be set to `true`.

   For compatibility, Druid returns the HTTP header `X-Druid-SQL-Header-Included: yes` when all of the following conditions are met:
   * The `header` property is set to true.
   * The version of Druid supports `typesHeader` and `sqlTypesHeader`, regardless of whether either property is set.

* `context`: JSON object containing optional [SQL query context parameters](../querying/sql-query-context.md), such as to set the query ID, time zone, and whether to use an approximation algorithm for distinct count.

* `parameters`: List of query parameters for parameterized queries. Each parameter in the array should be a JSON object containing the parameter's SQL data type and parameter value. For a list of supported SQL types, see [Data types](../querying/sql-data-types.md).

    For example:
    ```json
    "parameters": [
        {
            "type": "VARCHAR",
            "value": "bar"
        }
    ]
    ```

    "errorClass": "Class of exception that caused this error.",
    "host": "The host on which the error occurred."
}
```

</TabItem>
</Tabs>

#### Client-side error handling and truncated responses

Druid reports errors that occur before the response body is sent as JSON with an HTTP 500 status code. The errors are reported using the same format as [native Druid query errors](../querying/querying.md#query-errors).
If an error occurs while Druid is sending the response body, the server handling the request stops the response midstream and logs an error.

This means that when you call the SQL API, you must properly handle response truncation.
For  `object` and `array` formats, truncated responses are invalid JSON.
For line-oriented formats, Druid includes a newline character as the final character of every complete response. Absence of a final newline character indicates a truncated response.

If you detect a truncated response, treat it as an error.

#### Sample request

The following example retrieves all rows in the `wikipedia` datasource where the `user` is `BlueMoon2662`. The query is assigned the ID `request01` using the `sqlQueryId` context parameter. The optional properties `header`, `typesHeader`, and `sqlTypesHeader` are set to `true` to include type information to the response.

### Cancel a query

Cancels a query on the Router or the Broker with the associated `sqlQueryId`. The `sqlQueryId` can be manually set when the query is submitted in the query context parameter, or if not set, Druid will generate one and return it in the response header when the query is successfully submitted. Note that Druid does not enforce a unique `sqlQueryId` in the query context. If you've set the same `sqlQueryId` for multiple queries, Druid cancels all requests with that query ID.

When you cancel a query, Druid handles the cancellation in a best-effort manner. Druid immediately marks the query as canceled and aborts the query execution as soon as possible. However, the query may continue running for a short time after you make the cancellation request.

Cancellation requests require READ permission on all resources used in the SQL query.

#### URL

`DELETE` `/druid/v2/sql/{sqlQueryId}`

#### Sample response

A successful response results in an `HTTP 202` message code and an empty response body.

### Query output format

The following table shows examples of how Druid returns the column names and data types based on the result format and the type request.
In all cases, `header` is true.
The examples includes the first row of results, where the value of `user` is `BlueMoon2662`.

## Query from deep storage

You can use the `sql/statements` endpoint to query segments that exist only in deep storage and are not loaded onto your Historical processes as determined by your load rules.

Note that at least one segment of a datasource must be available on a Historical process so that the Broker can plan your query. A quick way to check if this is true is whether or not a datasource is visible in the Druid console.


For more information, see [Query from deep storage](../querying/query-from-deep-storage.md).

### Submit a query

Submit a query for data stored in deep storage. Any data ingested into Druid is placed into deep storage. The query is contained in the "query" field in the JSON object within the request payload.

Note that at least part of a datasource must be available on a Historical process so that Druid can plan your query and only the user who submits a query can see the results.

#### URL

`POST` `/druid/v2/sql/statements`

#### Request body

Generally, the `sql` and `sql/statements` endpoints support the same response body fields with minor differences. For general information about the available fields, see [Submit a query to the `sql` endpoint](#submit-a-query).

Keep the following in mind when submitting queries to the `sql/statements` endpoint:

- Apart from the context parameters mentioned [here](../multi-stage-query/reference.md#context-parameters) there are additional context parameters for `sql/statements` specifically:

   - `executionMode`  determines how query results are fetched. Druid currently only supports `ASYNC`. You must manually retrieve your results after the query completes.
   - `selectDestination` determines where final results get written. By default, results are written to task reports. Set this parameter to `durableStorage` to instruct Druid to write the results from SELECT queries to durable storage, which allows you to fetch larger result sets. For result sets with more than 3000 rows, it is highly recommended to use `durableStorage`. Note that this requires you to have [durable storage for MSQ](../operations/durable-storage.md) enabled.

### Get query status

Retrieves information about the query associated with the given query ID. The response matches the response from the POST API if the query is accepted or running and the execution mode is  `ASYNC`. In addition to the fields that this endpoint shares with `POST /sql/statements`, a completed query's status includes the following:

- A `result` object that summarizes information about your results, such as the total number of rows and sample records.
- A `pages` object that includes the following information for each page of results:
  -  `numRows`: the number of rows in that page of results.
  - `sizeInBytes`: the size of the page.
  - `id`: the page number that you can use to reference a specific page when you get query results.

If the optional query parameter `detail` is supplied, then the response also includes the following:
- A `stages` object that summarizes information about the different stages being used for query execution, such as stage number, phase, start time, duration, input and output information, processing methods, and partitioning.
- A `counters` object that provides details on the rows, bytes, and files processed at various stages for each worker across different channels, along with sort progress.
- A `warnings` object that provides details about any warnings.

### Get query results

Retrieves results for completed queries. Results are separated into pages, so you can use the optional `page` parameter to refine the results you get. Druid returns information about the composition of each page and its page number (`id`). For information about pages, see [Get query status](#get-query-status).

If a page number isn't passed, all results are returned sequentially in the same response. If you have large result sets, you may encounter timeouts based on the value configured for `druid.router.http.readTimeout`.

Getting the query results for an ingestion query returns an empty response.

#### URL

`GET` `/druid/v2/sql/statements/{queryId}/results`

#### Query parameters
* `page` (optional)
    * Type: Int
    * Fetch results based on page numbers. If not specified, all results are returned sequentially starting from page 0 to N in the same response.
* `resultFormat` (optional)
    * Type: String
    * Defines the format in which the results are presented. The following options are supported `arrayLines`,`objectLines`,`array`,`object`, and `csv`. The default is `object`.
