Question asks for a staement to do the following.... and then gives the requirements.
Are we supposed to achieve it all in one statement? I don't see how you can insert into multiple tables in one statement.
Would need minimum of three statements.

Any ideas?

There is a way to insert into each table depending on the criteria with only one statement. Have a look at the INSERT WHEN clause. I don't have my books with me so I can't give the reference off-hand.

I used the INSERT WHEN clause. So if the condition is true, then insert into one table and then if the condition is not true, insert into the other tables. So basicall, INSERT WHEN....ELSE...

I also used a SET OPERATOR.

I found this question very tricky but it gives me the same results as per the assignment if I enter in < 6000.

I can't seem to find reference to "INSERT WHEN" clause?

It is in the second book (manual "something" II) - I think chapter 3 or 5 (you'll have to page around a bit but it is there). Btw. I think the manuals are terrible for finding anything and learning SQL. Look on the Oracle website, they have free PDF manuals that are much better for finding stuff. Just make sure that whatever you use is in the syllabus.

I did eventually find reference to "WHEN" command, to do with CASE and DECODE.
I agree with what you say about finding stuff. There is an index at the end of manual 2, but "WHEN" wasn't in it.

I have now managed to find some examples on the 'net, so will try again tonight.

I just remembered it is in the chapter called "Chapter 5: Manipulating Large Data Sets" or something like that, towards the end of the chapter.

Have a look at Lesson 3 in the second manual. It shows you how to insert into multiple tables and also how to set conditions to insert.

Sorry, yes it's in chapter 3, not 5 like I said previously.

Thanks for the help.
Figured it out, got the correct results, although I'm not sure I quite understand the question, but anyway!
Time to put them all together and submit!!smileys with beer
