Hi Taifun and all,
I use the sqlite extention to call "select id,sqrt(id) from tabelle". ( the id is in the table)
"select id from tabelle" works.
same with ... power(id,2) ...
The function is not available, but in https://sqlite.org/lang_mathfunc.html#pow the functions are listed.
So I guess your sqlite is with less functions? Or what can I do?
