If the str parameter is not of the STRING, BIGINT, DOUBLE, DECIMAL, or DATETIME type, an error will be returned. If the str value is NULL, a NULL is returned. Example Example 1: Retrieve the ASCII code of the first character in the string abcde. Example statement: -- The return val...
ASCIIEncodingdoes not provide error detection. Any byte greater than hexadecimal 0x7F is decoded as the Unicode question mark ("?"). Caution For security reasons, you should use theUTF8Encoding,UnicodeEncoding, orUTF32Encodingclasses and enable error detection instead of using theASCIIEncodingclass...
