  • Inserting multiple types into an SQLite database with Python

    - by mankoff
    I'm trying to create an SQLite 3 database from Python. I have a few types I'd like to insert into each record: A float, and then 3 groups of n floats, currently a tuple but could be an array or list.. I'm not well-enough versed in Python to understand all the differences. My problem is the INSERT statement. DAS = 12345 lats = (42,43,44,45) lons =

  • Prevent sqlite INJECTION ATTACKS on your own iPhone?

    - by Bonnie
    I always take precautions regarding SQL INJECTION ATTACKS when data is saved between someone's iPhone and a remote database on the cloud. But is it also necessary to do the same... when just saving data (using sqlite) from someone's cell phone, to a database that's just on their own phone? What's the worse they can do? Delete their own data (or

  • Dealing w/ Sqlite Join results in a cursor

    - by Bill
    I have a one-many relationship in my local Sqlite db. Pretty basic stuff. When I do my left outer join I get back results that look like this: the resulting cursor has multiple rows that look like this: A1.id | A1.column1 | A1.column2 | B1.a_id_fk | B1.column1 | B1.column2 A1.id | A1.column1 | A1.column2 | B2.a_id_fk | B2.column1 | B2.column2

  • SQLite doesn't have booleans or date-times...but C# does

    - by DanM
    I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed

  • Database file is inexplicably locked during SQLite commit

    - by sweeney
    Hello, I'm performing a large number of INSERTS to a SQLite database. I'm using just one thread. I batch the writes to improve performance and have a bit of security in case of a crash. Basically I cache up a bunch of data in memory and then when I deem appropriate, I loop over all of that data and perform the INSERTS. The code for this is

  • Implement subitem in SQLite

    - by Mohit Deshpande
    How could I implement a sub item where the item would have a parent to that of the same item. For example, I have a database that holds tasks/todos. Each todo has a title(TEXT), completed(INTEGER [1 if true, 0 if false]), and due date(TEXT) column. I would like to add functionality to have subtasks, where a task could possibly have a

  • sqlite & python - only pulls the first result

    - by pencilNero
    This is pretty strange (admitedly, this is my first attempt with python / sqlite), but I can seem to get all of the rows if I do a fetchAll(), but other than that - no matter what I try, always ends up in the db only returning the first row - the second iteration stops because a null is returned.

    I am using core data for my app and I never had any problems adding or removing columns until recently. But now even if I make changes to my xcdatamodel and generate new and updated entity h/m files, sqlite doesn't seem to be picking up the changes. I actually went over to the documents

  • SQLite: does data type depend on the quotes?

    - by Septagram
    In SQLite, the datatype of a value is associated with the value itself, not with the column type. So suppose we have a table with an integer primary key "id" and an integer column "some_number". If I do a query like this: INSERT INTO mytable (id, some_number) VALUES (NULL, "1234")

  • How should I deal with sqlite errors?

    - by Dustin
    I have a long running application written in a mix of C and C++ that stores data in sqlite. While I am confident that committed data will remain available (barring mechanical failure) and uncommitted data will not be, it's not clear to me what I can do with this sort of middle
