### Question
State the width and height of the object with the class of 'van' in image 1.

### Hint
The bounding box's W and H abbreviations stand for the object's width and height respectively; class of 'van' in image 1 refers to OBJ_CLASS = 'van' where IMG_ID = 1;

### SQL
SELECT T1.H, T1.W FROM IMG_OBJ AS T1 INNER JOIN OBJ_CLASSES AS T2 ON T1.OBJ_CLASS_ID = T2.OBJ_CLASS_ID WHERE T1.IMG_ID = 1 AND T2.OBJ_CLASS = 'van'

### Question
State the coordinate of X and Y for the object with the attribute of 'sparse' in image 1.

### Hint
coordinates of X and Y for the object refer to X and Y coordinates of the bounding box; attribute of 'sparse' in image 1 refers to IMG_ID = 1 where ATT_CLASS = 'sparse';

### SQL
SELECT T3.OBJ_SAMPLE_ID, T3.X, T3.Y FROM ATT_CLASSES AS T1 INNER JOIN IMG_OBJ_ATT AS T2 ON T1.ATT_CLASS_ID = T2.ATT_CLASS_ID INNER JOIN IMG_OBJ AS T3 ON T2.IMG_ID = T3.IMG_ID WHERE T3.IMG_ID = 1 AND T1.ATT_CLASS = 'sparse'

### Question
Calculate the percentage of object samples that are related to street lights.

### Hint
DIVIDE(COUNT(OBJ_SAMPLE_ID where OBJ_CLASS = 'street lights'), COUNT(OBJ_SAMPLE_ID)) as percentage;

### SQL
SELECT CAST(SUM(CASE WHEN T2.OBJ_CLASS = 'street lights' THEN 1 ELSE 0 END) AS REAL) * 100 / COUNT(T1.OBJ_SAMPLE_ID) FROM IMG_OBJ AS T1 INNER JOIN OBJ_CLASSES AS T2 ON T1.OBJ_CLASS_ID = T2.OBJ_CLASS_ID

### Question
How many images have "vegetable" and "fruits" as their object classes?

### Hint
images refer to IMG_ID; "vegetables" and "fruits" as object classes refer to OBJ_CLASS = 'vegetables' and OBJ_CLASS = 'fruits';

### SQL
SELECT COUNT(T1.IMG_ID) FROM IMG_OBJ AS T1 INNER JOIN OBJ_CLASSES AS T2 ON T1.OBJ_CLASS_ID = T2.OBJ_CLASS_ID WHERE T2.OBJ_CLASS = 'vegetables' OR T2.OBJ_CLASS = 'fruits'

### Question
What is the image ID with a predicted class of "parked on"?

### Hint
predicted class of "parked on" refers to PRED_CLASS = 'parked on';

### SQL
SELECT DISTINCT T1.IMG_ID FROM IMG_REL AS T1 INNER JOIN PRED_CLASSES AS T2 ON T1.PRED_CLASS_ID = T2.PRED_CLASS_ID WHERE T2.PRED_CLASS = 'parked on'

### Question
List all the object classes of the images that have a (5,5) coordinate.

### Hint
object classes refer to OBJ_CLASS; (5,5) coordinates refer to X and Y coordinates of the bounding box where X = 5 and Y = 5;

### SQL
SELECT T2.OBJ_CLASS FROM IMG_OBJ AS T1 INNER JOIN OBJ_CLASSES AS T2 ON T1.OBJ_CLASS_ID = T2.OBJ_CLASS_ID WHERE T1.X = 5 AND T1.Y = 5
