```sql
select *,if(@lastOne=userName,'',@lastOne:=userName) flag from (select * from table order by userName,postDate desc) a,(select @lastOne :='')b where flag <> ''
```
select *,if(@lastOne=userName,'',@lastOne:=userName) flag from (select * from table order by userName,postDate desc) a,(select @lastOne :='')b where flag <> ''

```Javascript
var bool = true;
var ret='';
$.ajaxSettings.async = false;
while(bool){
$.getJSON(Url, requestData, function (rv) {
var respOnse= rv.Value;
ret = response.Process;
if (ret == 100) {
console.log("Done!");
bool = false;
}
});
}
console.log('已完成:'+ret+'%!');
$.ajaxSettings.async = true;
;!function(){
var dOneCallback= function(){console.log('已完成:100%!');};
var getPrecent = function(){
$.getJSON(Url, requestData, function (rv) {
var respOnse= rv.Value;
ret = response.Process;
if (ret == 100) {
console.log("Done!");
doneCallback();
}else{
setTimeout(getPrecent,200);
}
});
};
}();
```
var bool = true;
var ret='';
$.ajaxSettings.async = false;
while(bool){
$.getJSON(Url, requestData, function (rv) {
var respOnse= rv.Value;
