SQL*Loader : data loading with treatments

Question

i want to load some data with SQL*Loader by the following steps: -load some columns of data in the text file. -make transformations into some data during loading. my file lines format is a sequence of like this:

123 G 100 data 122 EGG ....
123 G 100 date2 122 EGG ....

firstly : just the value columns must be loaded, i mean : "G", "data" and "EGG" for the first line and "G", "data2" & "EGG" for the second line etc. the s corresponf to the field ids.

secondly : i need in some case, to split some columns to 3 parts and that will correspond to 3 records in table.

Global issue : I need just to know how to couple date loading and date treatment at same time.

also, in need in some case, to split some columns to 3 parts and that will correspond to 3 records in table.

Answer 1

Firstly: Every column in the data file needs to be accounted for. If you don't want to load it to a table, just specify it as FILLER:

...
( NBR1  FILLER   -- '123'
 ,data1 char     -- 'G'
 ,NBR2  FILLER   -- '100'
 ,data2 char     -- 'data'
 ,NBR3  FILLER   -- '122'
...

The rest of your questions need some before/after examples of what you are working with and what you expect in order to answer.
