Hi, I'm trying to find this in already defined C functions, but with no luck.. What is the set of commands I need to use when I want to insert a row into a table? The row is just array of <dbl, dbl, int, int>. Also, how do I pass a row as a parameter to the function? Do I need to pass all of the columns separately, or can I pass the whole row as an array? Thank you for pointing me the right direction. Cheers, Jiri Nadvornik Astronomical Institute AV CR Stellar department Czech Republic <mailto:nadvornik.ji@gmail.com> nadvornik.ji@gmail.com
