This this code: SELECT SUBSTRING(posted,1,4) as year FROM styles reader = cmd1.ExecuteReader(CommandBehavior.CloseConnection); reader.Read(); Response.Write(reader[0].ToString());

This this code:

SELECT SUBSTRING(posted,1,4) as year FROM styles
reader = cmd1.ExecuteReader(CommandBehavior.CloseConnection);
reader.Read();
Response.Write(reader[0].ToString());

I only get the string “System.Byte[]” printed out. How come?

If I use the software Mysql Query Browser I get the actual string from my database.

I understand that “Byte[]” is an arraylist but how do I convert this to a pure string?

The “posted”-field in my database contains a date like “2010-04-04 13:23:00” and I want to get only the year by using SUBSTRING.

    The correct query is 

    SELECT DISTINCT SUBSTRING(CONVERT(varchar, posted, 111),1,4) as year FROM styles

    It equals to 

    SELECT STR(YEAR(posted)) as year FROM styles-- YEAR returns int statement

    First argument is converted, than substring extracted.
    111 – the convertion format: http://www.mssqltips.com/tip.asp?tip=1145

    Also try 

    reader["year"].ToString();

    as far as you use this alias.
