三种方法判断字符串中是否含有字母

方法一：
select distinct b.securno,substr(b.securno,2)
  from bond_deal_detail b
 where b.securno!=translate(b.securno,'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ','0123456789');

方法二：
select distinct securno,substr(b.securno,2) from bond_deal_detail b
        where upper(b.securno)!=b.securno
        or lower(b.securno)!=b.securno

方法三：
select distinct b.securno from bond_deal_detail b where ltrim(b.securno,'0123456789') is not null;
