This is how you can insert into an identity column:
CREATE TABLE my_table (id INTEGER PRIMARY KEY AUTOINCREMENT, name COLLATE NOCASE);
CREATE TABLE temp_table (name COLLATE NOCASE);
.import predefined/myfile.txt temp_table
insert into my_table (name) select name from temp_table;
myfile.txt is a file in C:\code\db\predefined\
data.db is in C:\code\db\
myfile.txt contains strings separated by newline character.
If you want to add more columns, it's easier to separate them using the pipe character, which is the default.
