Thanks for your response. Do you know if extending FlatFileVTI will work
as fast as the built-in IMPORT_TABLE function? Before using CALL
SYSCS_UTIL.SYSCS_IMPORT_TABLE, I had written my own class that would
read a delimited file and use the INSERT INTO statement to populate my
Derby db. However, it took my class 1 hour to import a file but it only
took one minute when I used SYSCS_UTIL.SYSCS_IMPORT_TABLE. Will
extending FlatFileVTI work a quickly as using SYSCS_UTIL.SYSCS_IMPORT_TABLE?
Thanks

Hi Patrick,
You can write a table function to help you out here. Your table
function will open your file, throw away the header, and then loop
through the lines in the file. I would recommend extending something
like FlatFileVTI (in Derby's demo directory). You can look at
PropertyFileVTI (in the same directory subtree), which will show you
how to extend FlatFileVTI. Once you declare your table function (let's
call it MyFileReader), you can then use it to populate your table as
follows:
insert into STAFF
select * from table( MyFileReader( 'myfile.del' ) ) s
Hope this helps,

I have a comma delimited file that contains a header in the first row
of the file. The header contains column names. If I manually create a
new file without the header, I can successfully import the new file with
CALL
SYSCS_UTIL.SYSCS_IMPORT_TABLE(null,'STAFF','myfile.del',null,null,null,0);
Creating the new file in my Java application is too time consuming
for it to be a good solution. Is there a way of importing a delimited
file with a header in the first row? Or, a way to import and ignore
the first row of the file being imported?
Thanks
