I have a table in my PieCloudDB database that has two columns:"vegetable" and "fruit". There are some redundant data. How can I get the distinct data and merge them in one column?
Vegetable | Fruit |
---|---|
carrot | cherry |
carrot | apple |
cabbage | peach |
mushroom | cherry |
pepper | orange |
pepper | strawberry |
Distinct_Column |
---|
peach |
carrot |
cabbage |
pepper |
mushroom |
strawberry |
cheery |
orange |
apple |
Try this will give the results you want:
SELECT distinct_column FROM
(
SELECT fruit AS distinct_column FROM PieCloudDB
UNION
SELECT vegetable AS distinct_column FROM PieCloudDB
) AS distinct_values;
