在C语言的字符串中，用/" 这样就能输入双引号了.
在Delphi中，单引号是怎么处理的呢？
例如，我的字符串是
select * from mytable where name like '%xu%'
我把它赋值给变量str,怎样写？

delphi里面的"#"和C里面的"/"差不多.

delphi的字符串是用单引号的，双引号可直接在字串中引用
若要在字串中用单引号，则只需用两个单引号即可
如：
s:='select * from mytable where name like ''%xu%''';
s:='select * from mytable where name like "%xu%"'
s:='select * from mytable where name='''+s1+'''';

或者a:='select * from mytable where name like '+#39+'%xu%'+#39;
