Hi,

I have a plain text file which show records like this:

aa;4854;absdef;705623
aa;508564;uhyfs;5623
cc;504853;nkfos;708565
aa;856;hdbsna;244
ee;50856;erase;854
i want to truncate from second field "50" if second field starts with "50" and
truncate from fourth field "70" if fourth field starts with "70" and
append second field of between first and third character (eg. "485") to fourth field if length of fourth field equal 3 and
insert records to table which named second field of between first and third character
i mean;
SQL> select * from A_485;
aa 4854 20040519 5623
cc 4853 8465465 8565

SQL> select * from A_856;
aa 8564 8546526 5623
aa 856 658524 856244
ee 856 84652 856854

How can I write up the control file properly

sorry my english,

thanks,
