Re: [MonetDB-users] I'm looking for a fast way to write data to the DB from a scripting language.

Dear JJ Thanks for using MonetDB. Please could you identify the platform you use MonetDB on and its version? Moreover, the message below indicates a possible problem we are not aware of. Can you provide a micro example that illustrates the failed calls, e.g. a 5 line PHP program to localize the bug. thanks in advance in improving the code base. regards, Martin JJ Jakosky wrote:

Thank you for replying quickly. Ruby would be a good choice.

I'm not clear about MAPI. I only know of Mail API. Does this mean Monet API?

I see a reference to the MAPI include files. Can you please outline the first steps I can take to get this going in Ruby? Can I compile in Cygwin or do I need to do it on Linux?

Thanks, Jay

Good morning Jay,

you can use the Ruby MAPI Wrapper => MAPI calls through Ruby. It's elegant and simple and was used to implement the Ruby on Rails adapter for MonetDB. Plus, from what I see in the SWIG input file, the insert and copy_from functions should be implemented in the Ruby MAPI Wrapper. If you want to go the Ruby way, you may find the files in the MonetDB clients package or at http://rubyforge.org/projects/monetdb-ror/ as part of the Ruby on Rails MonetDB adapter.

----------------------------------------------------------------------------------------------- Hi,

I have 50 million rows and 15 columns that I'd like to put into one table. My first attempt to transfer them was through PHP using the monetdb_query method. This is causing a lot of disk thrashing and my throughput is about 100 rows/sec.

I get an "undefined function" error for both monetdb_insert and monetdb_copy_from.

I would like to find a fast method, but from inside a common scripting language.

Thanks, Jay
