其中我要Expr10 的值有四种情况A、N、R、H，我要让每行都是A或N的显示出来，只要有任何一个R、H的就不显示
我现在的问题就是那个ecn_num是22和25的，他的行里Expr10的值有一个是不满足条件用了我的语句还是会显示出来，我现在是要不管22的和25的有多少条，只要有一条不满足，这个22或25就不显示，这语句该怎么写，我想了半天也没想出来，我只知道我的那个语句只要有一个成立就会显示，反过来我就想不出怎么弄了，请指教啊！（还有，这个是在vb6中做的一个东西）
rs.Open "select DISTINCT ecn_num from VIEWECN where Expr10<>'R' and Expr10<>'H' and (Expr10='A' or Expr10='N')", cn, adOpenStatic, adLockReadOnly
--------------------编程问答-------------------- select DISTINCT ecn_num from VIEWECN where Expr10='A' or Expr10='N'
这样不就行了吗？ --------------------编程问答-------------------- select DISTINCT ecn_num from VIEWECN where Expr10 not in (R,H) --------------------编程问答--------------------
select DISTINCT ecn_num from VIEWECN where Expr10 not in ('R','H')
--------------------编程问答--------------------
