Danoja Dias commented on DERBY-4555:
------------------------------------
I think I found a way to get rid of above exception.
Calling the deleteFile method, before it creates.
SupportFilesSetup.deleteFile("pet.dat");
s.execute("call SYSCS_UTIL.SYSCS_EXPORT_TABLE (null, 'EX_PET', 'pet.dat' ,
null, null, null) ");
I am running tests now. I think all will be clean with this adjustment.
> Expand SYSCS_IMPORT_TABLE to accept CSV file with header lines

> The SYSCS_IMPORT_TABLE (and SYSCS_IMPORT_DATA) function allow import of data
> from external resources. In general, they can process CSV files that created
> with various tools - with one exception: the header line.
> While there is no accepted standard, most tools will include a header line in
> the CSV file with column names. This convention is supported in Excel and
> many other tools.
> My Request: extend the SYSCS_IMPORT_TABLe and SYSCS_IMPORT_DATA (and other
> related procedures) to include an extra indicator for the number of header
> lines to be ignored.
> As an extra bonus it will be help is the SYSCS_IMPORT_DATA will accept column
> names (instead of column indexes) in the 'COLUMNINDEXES' arguments. E.g., it
> should be possible to indicate COLUMNINDEXES of '1,3,sales,5,'. This feature
> will make it significantly easier to handle cases where the external input
> files is extended to include additional columns.
