+
+This tutorial is a continuation from the previous state example. This tutorial shows how to use SQL interface through CLI to access state data.
+
+## Prerequisites
+
+This guide uses `local` Fluvio cluster. If you need to install it, please follow the instructions at [here][installation].
+
+## Dataflow
+
+### Overview
+From previous examples we learned how to create and manipulate a state. Here we will do the same but also will use CLI interface to access it.
+
+### Collect-sensor-data
+
+#### 1. Define the state
+
+For this state, we will track the `latitude`, `longitude`, `sensor_status` and more parameters from the sensors.
+
+```YAML
+    states:
+      vehicle-data:
+        type: keyed-state
+        properties:
+          key:
+            type: string
+          value:
+            type: arrow-row
+            properties:
+              latitude:
+                type: f64
+              longitude:
+                type: f64
+              fuel_consumption:
+                type: u32
+              sensor_status:
+                type: string
+              engine_temperature:
+                type: i32
+```
+
+Here, the `key` is a string but the value is stored as an `arrow-row` which can contain multiple `properties`(acts like columns).
+
+#### 2. Assign key
+We will access the id from the sensor data to partition the state. 
+```YAML
+partition:
+  assign-key:
+    run: |
+        fn key_by_id(data: VehicleDataType) -> Result<String> {
+          Ok(data.vehicle_id)
+        }
+  update-state:
+    (...)
+```
+#### 3. Updating State
+To update the state in an `arrow-row`, we need to update the individual row's columns manual and call an `update()`.
+```YAML
+partition:
+  assign-key:
+    (...)
+  update-state:
+    run: |
+        fn update_temperature(data: VehicleDataType) -> Result<()> {
+            let mut vd = vehicle_data();
+
+            vd.latitude = data.latitude;
+            vd.longitude = data.longitude;
+            vd.fuel_consumption = data.fuel_consumption;
+            vd.engine_temperature = data.engine_temperature;
+            vd.sensor_status = data.sensor_status;
+            vd.update()?;
+            Ok(())
+          }
+```
+
+States are terminal so no other action will be run.
+
+In this example there is not other service consuming the state, we will use the SQL interface to access it from CLI.
+
+
+## Running the Example
+### Full Code
+Copy and paste following config and save it as `dataflow.yaml`.
+<CodeBlock language="yaml">{SqlCLi}</CodeBlock>
+
+### Running SDF
+To run example:
+```bash copy="cmd"
+$ sdf run
+```
+
+### Produce data
+We will produce some data to mimic sensors behavior. 
+```bash copy="cmd"
+$ echo '{ "timestamp": "2023-11-22T12:34:56Z", "vehicle_id": "V001", "latitude": 40.7128, "longitude": -74.0060, "speed": 60, "engine_temperature": 90, "engine_rpm": 2000, "fuel_consumption": 10, "sensor_status": "ok" }
+' | fluvio produce vehicle-sensor
+$ echo '{ "timestamp": "2023-11-22T12:35:01Z", "vehicle_id": "V002", "latitude": 34.0522, "longitude": -118.2437, "speed": 30, "engine_temperature": 85, "engine_rpm": 1500, "fuel_consumption": 8, "sensor_status": "failed"}
+' | fluvio produce vehicle-sensor
+```
+
+### Enter SQL Mode
+
+In the SDF interactive shell use the `sql` command to enter the SQL Mode:
+
+```bash
+>> sql
+SDF SQL version sdf-beta5
+Type .help for help.
+sql >> 
+```
+
+### Run queries on the SQL mode
+
+In the SQL mode we will be able to access the dataframe states of the dataflow.
+
+We can list the tables available with:
+
+```bash
+sql >> show tables
+shape: (1, 1)
+┌──────────────┐
+│ name         │
+│ ---          │
+│ str          │
+╞══════════════╡
+│ vehicle_data │
+└──────────────┘
+```
+
+We can also perform normal sql queries:
+
+```
+select * from vehicle_data
+shape: (2, 6)
+┌──────┬────────────────────┬──────────────────┬──────────┬───────────┬───────────────┐
+│ _key ┆ engine_temperature ┆ fuel_consumption ┆ latitude ┆ longitude ┆ sensor_status │
+│ ---  ┆ ---                ┆ ---              ┆ ---      ┆ ---       ┆ ---           │
+│ str  ┆ i32                ┆ u32              ┆ f64      ┆ f64       ┆ str           │
+╞══════╪════════════════════╪══════════════════╪══════════╪═══════════╪═══════════════╡
+│ V001 ┆ 90                 ┆ 10               ┆ 40.7128  ┆ -74.006   ┆ ok            │
+│ V002 ┆ 85                 ┆ 8                ┆ 34.0522  ┆ -118.2437 ┆ failed        │
+└──────┴────────────────────┴──────────────────┴──────────┴───────────┴───────────────┘
+
+sql >> select * from vehicle_data where sensor_status = 'failed'
+shape: (1, 6)
+┌──────┬────────────────────┬──────────────────┬──────────┬───────────┬───────────────┐
+│ _key ┆ engine_temperature ┆ fuel_consumption ┆ latitude ┆ longitude ┆ sensor_status │
+│ ---  ┆ ---                ┆ ---              ┆ ---      ┆ ---       ┆ ---           │
+│ str  ┆ i32                ┆ u32              ┆ f64      ┆ f64       ┆ str           │
+╞══════╪════════════════════╪══════════════════╪══════════╪═══════════╪═══════════════╡
+│ V002 ┆ 85                 ┆ 8                ┆ 34.0522  ┆ -118.2437 ┆ failed        │
+└──────┴────────────────────┴──────────────────┴──────────┴───────────┴───────────────┘
+```
+
+### Exit the SQL mode
+
+Use `.quit` or `.exit` to exit the SQL mode.
+
+```bash 
+sql >> .quit
+```
+
+## Cleanup
+
+Exit `sdf` terminal and clean-up. The `--force` flag removes the topics:
+
+```bash copy="cmd"
+$ sdf clean --force
+```
+
+
+## Conclusion
+
+We just implement example accessing arrow states through SQL interface. The following link contains another example using the data from multiple states to perform a JOIN Query
