List<view_attend__c> my = newList<view_attend__c>();

public class contr {
public View_attend__c acc{get;set;}
public view_attend__c getempl() {
List<view_attend__c> my = newList<view_attend__c>();
string st='';
st = ApexPages.currentPage().getParameters().get('id');
Listmy = [SELECT Login__c,status__c,Name_emp__C FROM view_attend__c where Name_emp__c =:st];
if(my.isEmpty() == false){
acc = my[0];
else{
ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.ERROR, 'The Account ID is invalid.');
ApexPages.addMessage(msg);
}
return acc;
}
public PageReference save() {
update acc;
return null;
}
}
Can you please paste the error here which you are getting? Also update Listmy to my, there is no Listmy variable in your class.

yes i updated it already to my but still getting error , Acctually what is this term st = ApexPages.currentPage().getParameters().get('id'); & actually does.
when i m doing it without any where clause it works but then i need to mention indvidual URL id of every user and it works for one Name only whose id is specified . else it showing error??
System.QueryException: List has no rows for assignment to SObject at VF page (if doing it without list type)
Class.contr.<init>: line 8, column 1
error is : contr Compile Error: unexpected token: '(' at line 6 column 53) (if i am specifying as list type)
i dont know why.. i am new in salesforce plz help me out.....
Please provide space between new and List<view_attend__c>()
List<view_attend__c> my = new List<view_attend__c>();
This will resolve Unexpected Error.
Coming to
st = ApexPages.currentPage().getParameters().get('id')
This will fetch the value of Id parameter from Url and assign that value too st variable.
For Ex: if your Url is /apex/pageName?id=001akelereAswed
Then your st value will be equal to 001akelereAswed
So ypu have to pass the variable Id in the url to get the records from view_attend__c otherwise the query will not return any records
