Question

NSString *titl = [database executeNonQuery:@"SELECT * FROM numberquestion"];

gives warning:

initialization makes pointer from integer without a cast

What is wrong?

Table “numberquestion” contains only one string “twenty” of type TEXT

Answer 1

Your database object seems to return an int on executeNonQuery:@"SELECT * FROM numberquestion".

If its some sort of generic database accessor I would expect an array or a similar structure as result for a “SELECT * …”.

But as the method reads “executeNonQuery:” it maybe only returns a state (encoded in an integer), because you don’t expect a result (exectuteNonQuery).
