Can't insert rows into sqlite database using objective c - ios

Question

For some reason, the following code is not storing any data in my sqlite database. The return code is SQLITE_DONE (101) so it is not giving me any error messages. The method is being called a number of times to populate a few rows in the database. Can anyone see where i'm going wrong?
- (void)storePersonInDatabase:(Person *)person {
const char *sql = "INSERT INTO PERSON (ID, NAME, NOTES, ADDRESS, PROMOTED, VEGETARIAN) values (?, ?, ?, ?, ?, ?)";
sqlite3_stmt *statement;
// Prepare the data to bind.
NSData *imageData = person.imageData;
NSString *personId = [person.personId stringValue];
NSString *personName = person.name;
NSString *address = person.address;
NSString *notes = person.notes;
NSString *isVegetarian = (person.isVegetarian) ? #"1" : #"0";
NSString *isPromoted = (person.isPromoted) ? #"1" : #"0";
// Prepare the statement.
if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL) == SQLITE_OK) {
// Bind the parameters (note that these use a 1-based index, not 0).
sqlite3_bind_text(statement, 1, [personId UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(statement, 2, [personName UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(statement, 3, [notes UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(statement, 4, [address UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(statement, 5, [isPromoted UTF8String], -1, SQLITE_TRANSIENT);
sqlite3_bind_text(statement, 6, [isVegetarian UTF8String], -1, SQLITE_TRANSIENT);
}
// Execute the statement.
int returnCode = sqlite3_step(statement);
if (returnCode != SQLITE_DONE) {
// error handling...
NSLog(#"An error occoured");
}
//This is how I set up the db
NSString *sqliteDb = [[NSBundle mainBundle] pathForResource:#"Persons" ofType:#"sqlite"];
if(sqlite3_open([sqliteDb UTF8String], &database) != SQLITE_OK){
NSLog(#"Unable to open database");
}

Answer 1

As a few people have suggested, you need to copy the database to a location outside of your project bundle. There you can read and write as you wish, otherwise you are essentially just creating new databases every time you try to run your 'storePersonInDatabase' method.
You should perform that same check that Daij-Djan provided before trying to interact with your database. You should also save the location or name of your database somewhere for easy access and file checking.

Answer 2

you show how you try to open a sqlite file in your app bundle
you cant write to your app bundle
the app bundle is read only
you need to copy it somewhere you can write to. It sounds like it should go to library/documents.
the pseudo code is:
if(!sqlite_already_in_library) {
[file_manager copyFileFrom:sqlite-in-bundle to:sqlite-in-library_path];
}
