Answer 1

create table $tableTodo ( 
  $columnId integer primary key autoincrement, 
  $columnTitle text not null,
  $columnDone integer not null)
''');

if you look carefully in the last line $columnDone integer not null it has no comma like the other 2 top lines, that's the problem in your code.

for more info

Happy coding

Answer 2

SQLite doesn't support trailing commas. Try removing the comma of your last statement about creating a table. for example

if you are writing like this;

$createdTime TEXT NOT NULL,

try instead;

$createdTime TEXT NOT NULL
