I have example:

SQL

SELECT 1 AS ID, 'a' AS NAME1, null AS NAME2
UNION
SELECT 1 AS ID, 'a' AS NAME1, 'b' AS NAME2

Result:

ID NAME1 NAME2
1 a null
1 a b

How can it combined ?

ID NAME1 NAME2
1 a b

Solution 1

you can't. You did a union asking for the null value, so you have it. I don't know what you mean by 'combined', but you are selecting the same thing as NAME1 in both cases, so there's nothing to combine. You're getting exactly what you asked for, and based on your question, there's nothing else you could want, apart from removing the union

My 5. Exactly, question makes no sense. OP ordered Coffee-Mocha and shouting why I am getting Chi-Latte. :)))

More correctly, he ordered a mocha, and shouted 'there's chocolate in my coffee !!' :P
