Hi All,

I have 4 files and each is about 240M, each containing DELETE and INSERT sql statements. I am using a script to read the sql statements and then apply them to the Sybase database, but it took more than 20 hours to finish. Any ideas how can I improve the efficiency?

Thanks in advance.

Update:

my sql statement just look like this: 

delete tbl_3 using a primary key 
insert tbl_3 
(
about 200 fields 
) 
select 
tbl_1's about 100 fields 
tbl_2's about 100 fields

And the script I am using just use Sybase::CTlib to apply the sql batchs to the Sybase server. And each of my file is a TRAN, containing 30k delete-then-insert sql statements.
