For the values that go in number fields, I check the Excel values for dbnull and set the parameters to 0, like this: cmd.Parameters(9).Value = 0. Npgsql throws an error “format specifier was invalid” If I do this: cmd.Parameters(9).Value = convert.todouble(0) then it works fine. > > Visual Basic 2010, Postgres 9.1, npgsql 2.0.12.0 > > Could somebody please explain this behavior? It's a long time since I've used BASIC in any form, but I think a hash suffix will make it a double; alternatively, put a decimal point in it. cmd.Parameters(9).Value = 0# cmd.Parameters(9).Value = 0.0 I usually use 0.0 to represent a floating-point zero in most languages.
