standardSetControllerを使用したページ付けのあるvisualforceページがあります。このページでは、ステータスによるフィルタリングも追加しました。つまり、新規、作業中、終了などです。現在、各ステータス値に対してcount（）を実行して、ページにステータスカウントを表示していますが、ステータスごとにクエリが必要ですが、これは非効率的です。より効率的な方法でステータスカウントを取得したいと思います。
これが私のコントローラーです：
public with sharing class myController {
public ApexPages.StandardSetController setCtrl{get; set;}
public String projId { get; set; }
public String clientName { get; set; }
private List<Ticket__c> TicketList = new List<Ticket__c>();
public myController()
{
projId = ApexPages.currentPage().getParameters().get('id');
clientName = [Select Client__r.Name From Project__c Where Id =: projId].Client__r.Name;
setCtrl = new ApexPages.StandardSetController(Database.getQueryLocator([select Ticket_Number__c, Name, Status__c, Description__c, Description_of_Resolution__c, CreatedDate from Ticket__c Where Project__c =: projId ORDER BY CreatedDate DESC]));
ticketList = (List<Ticket__c>)setCtrl.getRecords();
setCtrl.setPageSize(5);
}
public Integer getNewStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'New'];
}
public Integer getWorkingStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'Working'];
}
public Integer getResolvedStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'Resolved'];
}
public Integer getClosedStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'Closed'];
}
public Integer getCancelledStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'Cancelled'];
}
public Integer getReopenedStatusCount() {
return [select count() from Ticket__c Where Project__c =: projId and status__c = 'Reopened'];
}
public Boolean hasNext {
get {
return setCtrl.getHasNext();
}
}
public Boolean hasPrevious {
get {
return setCtrl.getHasPrevious();
}
set;
}
public Integer pageNumber {
get {
return setCtrl.getPageNumber();
}
set;
}
public Integer totalPages {
get {
totalPages = math.ceil((Double)setCtrl.getResultSize() / setCtrl.getPageSize()).intValue();
return totalPages;
}
set;
}
public void first() {
setCtrl.first();
}
public void last() {
setCtrl.last();
}
public void previous() {
setCtrl.previous();
}
public void next() {
setCtrl.next();
}
public List<Ticket__c> getTickets()
{
return (List<Ticket__c>)setCtrl.getRecords();
}
public void filterStatus() {
string myParam = apexpages.currentpage().getparameters().get('myParam');
setCtrl = new ApexPages.StandardSetController(Database.getQueryLocator([select Ticket_Number__c, Name, Status__c, Description__c, Description_of_Resolution__c, CreatedDate from Ticket__c Where Project__c =: projId AND Status__c =: myParam ORDER BY CreatedDate DESC]));
setCtrl.setPageSize(5);
}
}
