首先是oracle: String sql = select * from ( select t.*,rownum as num from (select * from user1 where 1=1 ; SetEntryString, Object set = m.entrySet(); Iterator io = set.iterator(); while (io.hasNext()) { Map.EntryString, Object me = (Map.En
首先是oracle:
String sql = " select * from ( select t.*,rownum as num from (select * from user1 where 1=1 ";
Set
Iterator io = set.iterator();
while (io.hasNext()) {
Map.Entry
if("username".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + " like '%"+ me.getValue() +"%'" ;
}
if("startTime".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + " >= '" + me.getValue() +"'";
}
if("endTime".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + "
}
if("sort".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " order by " + me.getValue() ;
}
if("order".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " " + me.getValue();
}
}
sql += " )t) " ;
sql = sql +" where num >=" + (currentPage-1)*pageSize +" and num
接着是MySQL:
String sql = " select * from user where 1=1 ";
Set
Iterator io = set.iterator();
while (io.hasNext()) {
Map.Entry
if("username".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + " like '%"+ me.getValue() +"%'" ;
}
if("startTime".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + " >= '" + me.getValue() +"'";
}
if("endTime".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " and " + me.getKey() + "
}
if("sort".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " order by " + me.getValue() ;
}
if("order".equals(me.getKey()) && !"".equals(me.getValue())){
sql += " " + me.getValue();
}
}
sql = sql +" limit " + (currentPage-1)*pageSize +" , " + pageSize ;
pageSize 该页有多少条数据,currentPage该页码
每个人都需要一台速度更快、更稳定的 PC。随着时间的推移,垃圾文件、旧注册表数据和不必要的后台进程会占用资源并降低性能。幸运的是,许多工具可以让 Windows 保持平稳运行。
