Follow the above “Stefano Falda” comment, that contains the UTF8 fix.

Hey,
thanks for the great Wrapper.

Is it possible to display characters like german umlaute (ä, ö, ü) correctly?

thanks!

Thank you! This saves me at least an hour of coding!

Neat wrapper. I’ve noticed a few things missing.

Most importantly, since the executeQuery method returns an array of dictionary object, the only way to get the column names is to get the keys from one of the dictionary (row) objects (eg using allKeys). Unfortunately, keys are returned from a dictionary in no guaranteed order. So, although your wrapper code adds the cells of the result in order of columns generated by the SQLite query, when we extract the column names from the resulting dictionary rows, the order often changes.

For simple queries on tables, the order is most often consistent with the query. But when querying a view, for instance, the order is most often changed.

You need to provide a hook to grab the column names of the query result as an ordered array.

Similarly, you need to provide a way to grab the declared_types of the result columns.

Is there any cost to use your library? Do you accept modification submissions?

Hope this helps,
Tom

Wow. I found this about 6 months too late. Could have saved me a lot of effort. I’m new to DB development (laughable in itself for a 20-year veteran programmer) and I keep thinking “There has to be an easier way — so much duplicate code.” And here is the solution — certainly good enough for my use.

Thank you!

Hi Matteo,
I’ve found that your code has some problem with accented characters, so I’ve modified the columnData routine:
if (columnType == SQLITE_TEXT) { // const unsigned char *text = sqlite3_column_text(stmt, index); // return [NSString stringWithFormat:@"%s", text]; char *str = (char *)sqlite3_column_text(stmt, index); return (str) ? [NSString stringWithUTF8String:str] : @”"; }

Thanks for posting your code.
