Hi Tom,
If life was easy, everything would just come in the format I'd like it. But
since it isn't, I need to create records like this one:
cdate | ctime | countrycode | areacodex | success | carrier |
duration| phonenumber | areacode | pseq | loadno | frline | entity |
loaddate | loadtime | prefix | toline | dur306 | dur180180 | recno
------------+----------+-------------+-----------+---------+---------+------
----+-------------+----------+------+---------+--------+--------+-----------
-+----------+--------+--------+--------+-----------+---------
2001-07-15 | 23:55:52 | 98 | 0 | f | 53092 |
48| 11970 | | 0 | 8280646 | 2017 | 001 | 2001-07-16 |
02:05:48 | 092 | 2116 | 0.8 | 3 | 5493891
>From an input file where the records looks like this one:
020-13 016-05 07-15-2001 23:59:07 00:00:59 09678634321208
78634321208
0000005300 ^M
(yes, that is a crtl-M at the end of the record, believe it or not :). If
there is any other way of getting this data into the database, I would love
to know about it. I have written a pretty complex routine to scan the phone
number in the input record to figure out what country is called and then,
within the country, which area was called. Country codes can be 1, 2 or 3
digits long.
As you can see, this is not a simple 'import' where I simply use 'copy'.
What it looks like I will do is to import this into a temp record, which I
then cut to pieces, extracting the info I want. Once I have what I need to
create the actual record, I can delete the temp record.
Best regards,
Chris
