Hi. I have two question about the Index in SQL 2005. First Question. At some point I hear that not it's good have or Create an Index on a column the type DATETIME. For example If I have a table with the columns First_Name, Last_Name and Date_of_Birth not it's recommended Create an Index on the column Date_of_Birth. Second Question. My second question it's about order of the columns within the Index. For example Whenever I create an Index, I put in first place the column of type NUMERIC (int, tinyint, bigin, etc), secondly the column of type CHAR (varchar, nvarchar, char, nchar, etc), thirdly the column that have a lot of NULL values. Is this good or is there another way to analyze the order of the columns for an index? Thank.
