Yair Lenga commented on DERBY-4555:
-----------------------------------
Thanks for your work on the ticket.
I hate picking on details - but can you consider a better name than
'SYSCS_IMPORT_TABLE_SKIP_HEADER_LINES'. Something like
'SYSCS_IMPORT_TABLE_DELIMITED' or 'SYSCS_IMPORT_TABLE_BULK'.
The SKIP_HEADER_LINES is just (minor missing) feature. The important
enhancements is the ability to import data the semi-standard CSV/TSV file.
Also, can you comment on the 2nd item in the request: the ability to load
column by header name (in addition to column number). Is this included ? or
does it have to spill into a separate ticket.
Thanks

> 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.
