Question

Hi,
I need urgent help in framing the Query to get the date in Hiearchical format.
I tried but unable to:
The format is:
I have Table Test_A and the structure format is as
GroupNo orderheaderNumber customername orderLineNumber address1 address2 address3 city country
1001        101                       Arjun              12                        A1          A2          A3            C1     USA
1001        102                        Dam              13                        A11         A12         A13       C11     AUS
II have Table Test_B and the structure format is as
product OrderHeaderNumber Item Price Dept
SOAP     101                       1      32   10
paste      101                       2     80   20

paste      102                     2     80   20
shampoo 102                     3     100  30

It's rude (and counterproductive) to say things like "urgent" in your message.
What you're asking for is called a Master-Detail Report: you want rows from a Master table (test_a in this case), followed immediately by all related rows from a Detail table (table_b).  Report writers often have tools that make that kind of thing easy; SQL (and PL/SQL) do not.  You can do what you want in SQL, but you'll have to do a lot of work that a report writer would otherwise do for you.
The simplest way to do this in SQL is to do a UNION of 2 queries:
(1) a query involving just the master table, and
(2) a query involving just the detail table
When you do a UNION of 2 queries, both must produce the same number of columns, and the datatypes of the columns must be consistent.  You can include NULL columns to make both queries have the same number of columns, and conversion functions, such as TO_CHAR, so that (for example) you can put a NUMBER like groupno in the same column as a VARCHAR2 like product.
Do you really want interior column headings, such as
product                     OrderHeaderNumber Item Price Dept
in the middle of the output?  You can do that in SQL, but it's more complicated.  You may need a 3rd branch of the UNION. to produce those rows.
If you have trouble doing this, post your best attempt, and a specific question.
Whenever you have any question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
