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
