sqlldr a .csv with variable length columns into an oracle(8.1) table
Hi,
I have a .csv file of the following format:
Item, Resource,20-10-2004 10:04,20-10-2004 11:00
BL00002BB ,47 ,188,203
here there are only 2 date/time columns. there can be anywhere between 100-1000 date/time columns.
Im using Oracle 8.1 and would like to know the best way to load this into a table of
Resource_Table
start_time End time Item Resource Qty
20-10-2004 10:04 20-10-2004 11:00 BL00002BB 47 188
20-10-2004 11:00 20-10-2004 12:00 BL00002BB 47 203
etc.
any ideas?

would utl_file be a better option?
You need to adapt your model to your input. So, let's think a little. When you
have two date/time columns, you label them start_time and end_time. How would you label the columns if you have say four (4) date/time columns?

Hi muskware77,
if we have four time/date columns we still only have:
Resource_Table
start_time End time Item Resource Qty
20-10-2004 10:04 20-10-2004 11:00 BL00002BB 47 188
20-10-2004 11:00 20-10-2004 12:00 BL00002BB 47 203
20-10-2004 11:04 20-10-2004 11:00 BL00002BB 47 188
20-10-2004 12:00 20-10-2004 12:00 BL00002BB 47 203
thanks

A sqlloader session like this one may move towards the solution:
-- sqlldr userid=joehodge/yourpwd control=c:\load\sol01.ctl log=d:\load\sqlldr01.log
--your control file (sol.01.ctl) may look like this:
LOAD DATA
INFILE .csv
INTO TABLE Resource_Table
FIELDS TERMINATED BY ','
(starttime, End_time, Item, Resource, Qty)
-- sqlldr userid=joehodge/yourpwd control=c:\load\sol01.ctl log=d:\load\sqlldr01.log
--your control file (sol.01.ctl) may look like this:
LOAD DATA
INFILE .csv
INTO TABLE Resource_Table
FIELDS TERMINATED BY ','
(starttime, End_time, Item, Resource, Qty)

Hi bvanderveen,
apologies i did mean a variable number of columns!
my idea was to :
have a table with as many columns (col_1, col_2 etc) as Oracle allows as a staging table
sqlldr the .csv into this table
write a oracle procedure to take the first row ( e.g. Item, Resource,20-10-2004 10:04,20-10-2004 11:00) and put this into a table called column_header_description
col_number col_description
1 item
2 Resource
3 20-10-2004 10:00
4 20-10-2004 11:00
etc
I could then write another procedure(already sounding like a bit long winded!)
to insert into the Resource_Table:
Resource_Table
start_time End time Item Resource Qty
3 4 col_1.value col_1.value col_3.value
5 6 col_1.value col_1.value col_4.value
3, 4, 5 and 6 would be taken from the column_header_description and col_1.value from the staging table
after writing it all out there must be an easier way?

I think you will run into a limitation on the number of columns Oracle allows. You could have multiple staging tables linked in a 1 to 1 relationship, but I think you would be better served to try to make the input data more like what your final data will be (I assume you have some control over this, if not, that changes the problem).
Look at your final design. If you have a large number of times, I assume that there is more that start/end combinations, but some sort of intervals. If you normalize this, you will probably have separate tables, and your program sending over output can also normalize the data to be loaded. You can do some wizardry with sqlldr or utl_file, but I think this approach would be simpler and easier to implement and maintain.
When solving a problem, I try to start with making sure I am solving the "right" problem.
Let me know if my assumptions are wrong.

Hi,
due to limitations from the source system we have no control over the input.
the report can be run for any time frame so this could be a month or a year (which supports your comment on the number of columns Oracle allows).
I didnt quite understand the comments in your second paragraph, could you kindly elaborate

My second paragraph envisions at least two tables. Perhaps I do not understand your data. Is the final result going to be a table with four columns:
Resource_Table
start_time End time Item Resource Qty
3 4 col_1.value col_1.value col_3.value
5 6 col_1.value col_1.value col_4.value
or will there be additional time columns in this table? If there will be additional date/time cols, what will they mean? Will they be start_time2, end_time2, start_time3, etc?
Resource_Table
start_time End time Item Resource Qty
3 4 col_1.value col_1.value col_3.value
5 6 col_1.value col_1.value col_4.value
or will there be additional time columns in this table? If there will be additional date/time cols, what will they mean? Will they be start_time2, end_time2, start_time3, etc?
ASKER
there will only ever be 5 columns in this table.
Resource_Table
start_time End time Item Resource Qty
3 4 col_1.value col_1.value col_3.value
5 6 col_1.value col_1.value col_4.value
6 7 col_1.value col_1.value col_5.value
Resource_Table
start_time End time Item Resource Qty
3 4 col_1.value col_1.value col_3.value
5 6 col_1.value col_1.value col_4.value
6 7 col_1.value col_1.value col_5.value
So why will your source output file have more than 2 times? Even if it is a month's worth of data, I would expect that there would be a separate record for each time/resource/quantity.
What I would probably have is something like 2 tables:
RESOURCE_INFO
RESOURCE_ID NUMBER NOT NULL,
DESCRIPTION VARCHAR2(200)
PRODUCTION_DATA
RESOURCE_ID NUMBER NOT NULL (FK) ,
QUANTITY NUMBER,
START_TIME DATE,
END_TIME DATE
I think you need to pre-process your data file. I am guessing that they are sending you (in a one-month example, a record with the resource, and then quantity/start/end data for each data point. You should use java, C, or whatever to split this up so that each record matches somewhat your final data format. Are my assumptions about the data file correct?

Hi,
the first two lines of the file look like this. A user could also select an extra day/months worth of data

That's kind of what I thought. I think you need to parse this, and output it into another file that is in the format you want to load.
ASKER
when you say parse it, what approach would you use?
I haven't much java experience but am fairly experiencde in plsql.
my latest idea was to have a staging table with two columns
col_data blob
col_number number pk
and then sqlldr every line into col_data field and put a sequential number in the col_number .
then do some string manipulation on the blob.
will this be incredibly slow or should I use utl_file.get?

Hi,
thanks for your help bvanderveen.
I've decided to use utl_file.get

Hi,
happy to see you've got a solution. However, you may wish to ugrade to
Oracle9i R2 and use external table in the future. This will certainly improve the
performance and reduce the time you spend in these ETF (Extraction, Transformation and Load) efforts.
Plse see: http://www.oracle.com/technology/products/oracle9i/daily/sept19.html
Good luck.
