1.Using the following table:
 Code  CategoryName   LastUpdated
1 Cloths            01.01.2007
1 Wear            01.01.2006
1 Wears            03.10.2005
2 Computers            03.04.2007
2 Hardware & Software 01.02.2006
3 Office equipment   03.10.2006Write SQL statement to get all current category names (without the old values).
看这张表里的有重复的Code,查询在重复的Code里取最新时间里的一条记录(如Code中有三个1,取其中时间最新的01.01.2007,两个2中取最新时间是03.04.2007),实现如下图,写一条SQL语句Code  Category
1 Cloths
2 Computers
3 Office equipment
谢谢……
