variable number of fields in record
I have a data file in which the num fields can be different.
"name" numhost "host"
the numhost value decides how many "host" entries are going to be in the record.
"john" 1 "sunhost"
"mary" 2 "sunhost" "sunhost2"
I need to load thhis file in a table in oracle9i.
There are around a million records in the file so i dont want to use the regular perl file processing linewise.
Any insights as to how to achieve this efficiently would be great.
I started thing in terms loading the table using sqlloader and using varrays to collect the hosts .
which is fine , but the final table needs to have the host names separated by the commas, in a single record. and i am not able to think of away of selecting varray data from temp table and concatinating it as a comma separated string and inserting it into the main table.
again the volume of data needs to be taken care of too.
any help would be apreciated.
