Question

Hey guys, I’m just playing around with SQLite so this is new for me. I’ve got a view in which persons data can be both saved and found. The save-function and find-function work perfectly. Now, I’ve got a new view with a tableView in it. I want to get all the persons in the contacts-table and fill the list with it.

Untill now, I’ve got:

-(void)viewWillAppear:(BOOL)animated {
    const char *dbpath = [databasePath UTF8String];
    sqlite3_stmt *statement;

    if (sqlite3_open(dbpath, &contactDB) == SQLITE_OK)
    {
        NSLog(@"Opened DB");
        NSString *querySQL = [NSString stringWithFormat:@"SELECT name FROM contacts"];

        const char *query_stmt = [querySQL UTF8String];
        NSLog(@"could not prepare statement: %s\n", sqlite3_errmsg(contactDB));

        if (sqlite3_prepare_v2(contactDB, query_stmt, -1, &statement, NULL) == SQLITE_OK)
        //if (sqlite3_step(query_stmt) == SQLITE_DONE)
        {
            //NSLog(@"SQLite OK");
            NSLog(@"SQLite ok");
            //if (sqlite3_step(statement) == SQLITE_ROW)
            //{
                while(sqlite3_step(statement) == SQLITE_ROW) {
                    NSLog(@"SQLite ROW");
                    NSString *person = [[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, 0)];
                    [personsList addObject:person];
                }
            //} else {
            //    NSLog(@"Emtpy list");
            //}
            sqlite3_finalize(statement);
        }
        sqlite3_close(contactDB);
    }
    NSLog(@"Calling reload");
    NSLog(@"%@", personsList);
    [tabelView reloadData];
}

This is all in viewWillAppear. When the view is loaded and done, the log says:
2011-05-06 10:45:26.976 database[1412:207] Opened DB

2011-05-06 10:45:26.978 database[1412:207] could not prepare statement: not an error

2011-05-06 10:45:26.979 database[1412:207] Calling reload

2011-05-06 10:45:26.979 database[1412:207] (

)

So it seems the statement isn’t an error, but sqlite3_prepare_v2 isn’t SQL_OK after all. Any help?

EDIT: In the previous view, the statement for creating a person is: @"INSERT INTO CONTACTS (name, address, phone) VALUES (\"%@\", \"%@\", \"%@\")", name.text, address.text, phone.text];

The statement for finding someone is: @"SELECT address, phone FROM contacts WHERE name=\"%@\"", name.text];

These two statements work and the data is displayed.

I used const char *dbpath = [databasePath UTF8String];, but I forgot to put the following code above it:

// Get the documents directory
    NSString *docsDir;
    NSArray *dirPaths;
    dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

    docsDir = [dirPaths objectAtIndex:0];
    databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: @"contacts.db"]];
    const char *dbpath = [databasePath UTF8String];
