SQL的between and 语句的问题
SubDate 是nvarchar型的，
String RMY = new String(request.getParameter("RMY").getBytes("ISO8859-1"));
String RMM = new String(request.getParameter("RMM").getBytes("ISO8859-1"));
String RMY2 = new String(request.getParameter("RMY2").getBytes("ISO8859-1"));
String RMM2 = new String(request.getParameter("RMM2").getBytes("ISO8859-1"));
String Date1 =RMY+RMM+"01";
String Date2 =RMY2+RMM2+"31";
String strSQL="select * from InfoHt where SubDate between '"+Date1+"' and '"+Date2+"'";
可是这个sql语句不起作用，请指教！谢谢！
[解决办法]
between '"+Date1+" ' and '"+Date2+" '"; 不是这样写的
