In newer Therion releases (previously using 6.1.8 version) something has been changed for sql creation: column "nan" is produced when a survey doesn´t contain any centerline with (underground) lenght. So if there are only surface legs, an error importing sql file will occur based on line: insert into MAPS values (110, 32, 'velky_previs_elem', NULL, 3, 0.000, nan); Adding underground leg 1 1_ 0.00 0 0 to centerline changes result as following: insert into MAPS values (110, 32, 'velky_previs_elem', NULL, 3, 0.000, 0.000); I really don´t know how things work in these exports, hope this will help to improve things. Or maybe I am missing something. Pavel Dňa 2025-03-31 12:20 Pavel Herich napísal(a):
Hi all,
recently, when I try to import an sql Therion export in DB browser, an error message apears (in attachment):
Error importing data: Error in statement #67789: no such column: nan. Aborting execution.
Any idea what might be the problem? Especially how to find it in source Therion data...
