Re: Using functions in sqlldr cripples performance

John,
use your CTL file and sqlldr (external_table=generate_only, then look into
the log file) to get a script showing how to create an external table to
model the same data file, then use insert /+ append */
into ....
select ....put here the columns + sql expressions
from the_external_table;

 I have a Oracle 9 direct load sqlldr routine which provides adequate
performance but have now had a request to delete some characters from the
data during the load and set some fields to upper case.
However tests show that using UPPER or TRANSLATE in the sqlldr control
file has huge negative impact on performance of the load.

Anyone got a solution to this ?
