do i then also need to predefine tables in iris before i import data? i would ideally like to just have a .sqlite file that i can turn into a table with data

thanks for the prompt response, i was under the impression for 2 and 3 that I need to setup a database first then use jdbc to connect it iris. However, if I want to just import .sqlite files into iris, can I use both methods 2 and 3 without setting up a database with said .sqlite files
