sqlite 3 "SQL error 'out of memory' (7)" objc

Question

Hi can anyone point out what I'm doing wrong please? The error is this:

SQL error 'out of memory' (7)



  - (NSArray *)RecipeInfo
{    
    NSMutableArray *retval = [[NSMutableArray alloc] init];
    NSString *query = [NSString stringWithFormat:@"SELECT key, name FROM recipes WHERE type = \'%@\'", self.RecipeType];

NSLog(query);

sqlite3_stmt *statement;

if (sqlite3_prepare_v2(_database, [query UTF8String], -1, &statement, NULL) != SQLITE_OK)
{
    NSLog(@"[SQLITE] Error when preparing query!");
    NSLog(@"%s SQL error '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(_database), sqlite3_errcode(_database));

    }
    else
    {
        while (sqlite3_step(statement) == SQLITE_ROW)
        {
            int uniqueId = sqlite3_column_int(statement, 0);
            char *nameChars = (char *) sqlite3_column_text(statement, 1);
            NSString *name = [[NSString alloc] initWithUTF8String:nameChars];
            RecipeInfo *info = [[RecipeInfo alloc] initWithUniqueId:uniqueId name:name];
            [retval addObject:info];
        }

        sqlite3_finalize(statement);
    }
return retval;
}

The sql executes fine in the database management environment I use, it has to be something to do with the way I'm using the sql api, can anyone spot whats wrong?

You can get that error, confusingly, if you neglected to open the database and the pointer is NULL (or, as rmaddy says, if it's NULL for any reason). Put a log statement where you open the database and make sure that it was successful and that you have a valid sqlite3 pointer.
