Question

I have two database tables:

Definitions table has the following columns:

Id, Category

Sample data:

1, What is capital of USA ?
2, Who broke my glass ?

Options table has the following columns:

Id, DefinitionId, Value

Sample Data:

1, 1, New York
2, 1, Melbourne
3, 1, Lahore
4, 2, Boss
5, 2, My brother
6, 2, Your girlfriend

Please guide me how I can query ALL questions with All options, I need data like below:

"", 1, What is capital of USA ?
1,1, New York
2,1, Melbourne
3, 1, Lahore

"", 2,Who broke my glass ?
4, 2, Boss
5, 2, My brother
6, 2, Your girlfriend

Please guide

Answer 1

For this, use UNION ALL like so:

SELECT '' ID, DefinitionId, Category AS value FROM Definitions WHERE ID = 1
UNION ALL
SELECT Id, DefinitionId, Value FROM Options WEHRE DefentionID = 1;

Note that: it is better to JOIN the two tables like so:

SELECT 
  d.Id,
  o.Id,
  o.Value
FROM Definitions d
INNER JOIN Options o ON d.ID = o.DefinitionId
WHERE d.Id = 1;

And don’t consider to do this formatting in SQL;

Update: To get all questions, try this:

SELECT '' ID, ID AS DefinitionId, Category AS value FROM Definitions 
UNION ALL
SELECT Id, DefinitionId, Value FROM Options
ORDER BY DEFINITIONID, ID;

This will give you:
