Answer 1

Your items 1–3 (a–z, A–Z, and 0–9) are all subsets of item 4 (printable ASCII characters), so you need only concern yourself with the latter. The following query satisfies that criterion:

SELECT * FROM Delin
 WHERE alamat REGEXP '^[ -~]+$';

The character class [ -~], indicates the ASCII characters from space to tilde inclusive, which happens to be all of the printable ASCII characters and no others.

You can see it in an SQL Fiddle here: http://sqlfiddle.com/#!9/6c7b8/1

Terminology note: There is no such thing as "Extended ASCII." The ASCII character set corresponds to the numbers 0–127 inclusive. Any character corresponding to a number greater than 127 is not ASCII. The term "Extended ASCII" is often mistakenly applied to various non-ASCII encodings, none of which is an "extension" of ASCII in any official sense.
