    I have 2 tables:

    TableA
    item desc
    apple fruit
    dog animal

    TableB
    item desc
    cat animal
    egg food

    What is the SQL query to merge the two tables, and save it into TableC? This
    should be the output:
    item desc
    apple fruit
    dog animal
    cat animal
    egg food

    This works:


    Select item, desc from TableA
    UNION
    Select item, desc from TableB

    Problem though...
    How do I save it to a 3rd table named TableC?

    Adding "INTO TableC" in the 1st row doesn't work.

    If TableC is already built, these two separate queries would do it (but
    there's probably a better way!)

    INSERT INTO TableC SELECT Item, Desc FROM TableA;
    INSERT INTO TableC SELECT Item, Desc FROM TableB;

    SMartin's two successive append queries is one way; or, you can create
    an Append query based on the saved Union query; or you can use a
    Subquery:

    INSERT INTO TableC
    SELECT Item, Desc FROM
    (SELECT Item, Desc FROM TableA
    UNION
    SELECT Item, Desc FROM TableB);

Since you're here... we have a small favor to ask...

More people are visiting & reading SPN than ever but far fewer are paying to sustain it. Advertising revenues across the online media have fallen fast. So you can see why we need to ask for your help. Donating to SPN's is vote for free speech, for diversity of opinions, for the right of the people to stand up to religious bigotry. Without any affiliation to any organization, this constant struggle takes a lot of hard work to sustain as we entirely depend on the contributions of our esteemed writers/readers. We do it because we believe our perspective matters – because it might well be your perspective, too... Fund our efforts and together we can keep the world informed about the real Sikh Sikhi Sikhism. If everyone who writes or reads our content, who likes it, helps us to pay for it, our future would be much more secure. Every Contribution Matters, Contribute Generously!
