+# Queries
+
+#### 1) the description of all Function
+
+```sql
+SELECT `description` FROM `Function`
+```
+> [!NOTE|label:Result]
+> 
+> "description" <br>
+> "Fast backwards" <br>
+> "Raise up the low frequencies. Cut off frequency : 200 Hz" <br>
+> "Reduce the low frequencies. Cut off frequency : 200 Hz" <br>
+> "Fast forwards" <br>
+> "Tunes down" <br>
+> "Tunes up" <br>
+> "Plays to the next track" <br>
+> "Open or close the player's tray" <br>
+> "Pauses the current track" <br>
+> "Plays the selected track" <br>
+> "Select the preset 1" <br>
+> "Select the preset 2" <br>
+> "Select the preset 3" <br>
+> "Plays to the previous track" <br>
+> "Stores the current frequency to a preset" <br>
+> "Stops the current track" <br>
+> "Reduce the high frequencies.Cut off frequency : 4000 Hz" <br>
+> "Raise up the high frequencies. Cut off frequency : 4000 Hz" <br>

+> "Select the source of the input (BD, DVD, HDMI, ...)" <br>
+> "Select the Audio format to use with the current source (2ch stereo, 5.1, 7.2, 9.2, ...)" <br>
+
+
+#### 2) the `name` of manufacturers that have at least one entry in the `Model` table
+```sql
+SELECT `Manufacturer`.`manufacturerName`
+FROM `Manufacturer`
+WHERE EXISTS( SELECT *
+             FROM `Model`
+             WHERE `Model`.`manufacturerID`=`Manufacturer`.`manufacturerID`)

+> [!NOTE|label:Result]
+> 
+> "manufacturerName" <br>
+> "HEVs" <br>
+> "Sony" <br>
+> "Onkyo"
+
+
+
+#### 3) the `modelName` of device models together with the `manufacturerName` of their manufacturers
+```sql
+SELECT `Model`.`modelName`, `Manufacturer`.`manufacturerName`
+FROM `Model`, `Manufacturer`
+WHERE `Model`.`manufacturerID` = `Manufacturer`.`manufacturerID`
+```
+> [!NOTE|label:Result]
+>
+> "modelName","manufacturerName" <br>
+> "MHC-900","Sony" <br>
+> "SDi-Ampli-01","HEVs"

+> "SDi-Tuner-01","HEVs" <br>
+> "UBP-X800M2","Sony" <br>
+> "TX-RZ70","Onkyo"
+
+#### 4) the description of the Function with functionLabel “Stop”
+```sql
+SELECT `Function`.`description`
+FROM `Function`
+WHERE `Function`.`functionLabel` like 'Stop'
+```
+> [!NOTE|label:Result]
+> "description" <br>
+> "Stops the current track"
+
+#### 5) the `functionLabel` for `Function` with `functionID` > 10 and with a `description` containing the word “`preset`” (SQL wildcard character is “`%`”)
+```sql
+SELECT `Function`.`functionLabel`
+FROM `Function`
+WHERE `Function`.`functionID` > '10' AND `Function`.`description` like '%preset%'
+```
+> [!NOTE|label:Result]
+> "functionLabel" <br>
+> "Preset 1" <br>
+> "Preset 2" <br>
+> "Preset 3" <br>
+> "Save preset"
+
+#### 6) the product of the tables `Code` and `FunctionList` (with and without the `JOIN` keyword), as well as the number of entries in the resulting product table
+```sql
+
+```
+> [!NOTE|label:Result]
+>
