Tricky SQL query to DUMP to flat file

Question

Hi All,
I have used UTL file utility before to dump table data into a comma seperated file but this time I have a tricky problem.
I have a table called customers with the following fields
work_order_no, customer_no, contract_start_date, title, Name, first_name, street, street_no, bank_code, name, liason_name
and have a products table with following fields
work_order_number, material_type, material_number, qty
1. I need to write the customer details + product details of the customer into a comma seperated file as below
A
1001,
1234,
12.01.2004,
Mr. Dr.,
Alphs,
Thomas,
my street,
12,
1112,
Barclays,
Mr. Dr. Alphs Thomas,
<EOH> - is a fixed
1001,
M,
12,
1,
<EOL> is fixed
1001,
M,
12,
1,
<EOL> is fixed
1001,
M,
12,
1,
<EOF> is fixed
4 - total number of records
1 - total number of A type of records(in the first position
How do i write a Pl/Sql code which can be called from command prompt.
Thanks in advance

You can try this out and see if it works :
CURSOR to fetch the customers data
Loop
- Use a string to concatenate the cursor variables
- Use chr(10) to print the columns in seperate lines
i.e. lResult := x.work_order_no || ',' || chr(10)
|| x.customer_no || ',' || chr(10)
|| x.contract_start_date || ',' || chr(10)
|| x.liason_name || ',' || chr(10)
- Use Utl_File to write the formatted string to
the output file
- Use Utl_File to write constant '<EOH>' to the
output file
- Get all product details
- For each product details
Loop
lResult := x1.material_type || ',' || chr(10)
|| x1.material_number || ',' || chr(10)
|| x1.Qty || ',' || chr(10)
- Use Utl_File to write the formatted
string to the output file
- Use Utl_File to write constant '<EOL>' to
the output file
End Loop
End Loop
- Use Utl_File to write constant '<EOF>' to the output
file
- Use Utl_File to write counters to the output file
You can write the code in a PL/SQL script file called a.sql and save it on the server directory 'c:\a.sql'.
To run from the command prompt type:
c:\> sqlplus userid/pwd@connectstring @c:\a.sql
Hope this helps.
