How to separate the required fields from Custom Object record?

Question

I'm posting this question previously but i'm not achieving my goal for that i posting again

I have a custom object called Incident__c. and it has some fields

1. Imtpact__c
2. Incident_state__c
3. Short_description__c
4. Contact_type__c

Note : all fields are check box fields

from visualforce page i'm saving Incident__c record

when i'm saving the record i checked only two fields and the remaining two fields are unchecked and i saved that record.

now my requiremt is i want two query only those checked two fields from the saved record

how can i achieve this

this is my apex class for saving the Incident records

public class DataInsert {

     public Boolean impact {get;set;} 
     public Boolean incident_state {get;set;} 
     public Boolean short_description {get;set;} 
     public Boolean sys_id {get;set;} 
     public Boolean contact_type {get;set;} 
     public Boolean u_sftype {get;set;} 
     public Boolean sys_updated_onONLast {get;set;}


     List<Incident__c> lst = new List<Incident__c>();

     public PageReference doInsert() {

        Incident__c objdlt = new Incident__c();   

       if(impact){ 
          objdlt.impact__c=impact ;
        }       

        if(incident_state){
           objdlt.incident_state__c=incident_state;
        }

        if(short_description){
           objdlt.short_description__c=short_description;
        }

        if(contact_type){
           objdlt.contact_type__c=contact_type;
        }


        insert objdlt; 
        lst.add(objdlt);

     }      
}

Here suggest anyway to get the only checked fields from the saved Incident__c record.

Thanks In Advance

Hi here is an example which you can try it out,

Account acc = new Account(name='acc', myCheckbox__c = true);
insert acc;
Schema.DescribeSObjectResult objSchema = Account.sObjectType.getDescribe();
Map<String, Schema.SObjectField> fieldMap = objSchema.fields.getMap();
Set<String> fields = new Set<String>(); 
for (String fieldName : fieldMap.keySet()){
    SObjectField sfield = fieldMap.get(fieldName);
    schema.describefieldresult dfield = sfield.getDescribe();
    if(acc.get(fieldName) == true) {
        if(dfield.isCustom() && String.valueOf(dfield.getSoapType()) == 'Boolean') {
            system.debug(acc.get(fieldName));
            fields.add(fieldName);
        }  
    }
}

in this example you in fieleds set you will get the set of fields which is checked(true). In this example I'm considering only custom fields. Hope it helps you.

Answer 2

if you want all checked fields through query you can get by querying your object --

[Select your fields reqiued FROM Custom Object Name WHERE Checkbox1=True || Checkbox2=True || Checkbox3=True || Checkbox4=True]

like this you can get only the checked fields.please let me know if it works !!

I have modified the code and comment on the changes : -

public class DataInsert {

     public Boolean impact {get;set;} 
     public Boolean incident_state {get;set;} 
     public Boolean short_description {get;set;} 
     public Boolean sys_id {get;set;} 
     public Boolean contact_type {get;set;} I have modified the code and comment on the changes : -

    public class DataInsert {

         public Boolean impact {get;set;} 
         public Boolean incident_state {get;set;} 
         public Boolean short_description {get;set;} 
         public Boolean sys_id {get;set;} 
         public Boolean contact_type {get;set;} 
         public Boolean u_sftype {get;set;} 
         public Boolean sys_updated_onONLast {get;set;}


         List<Incident__c> lst = new List<Incident__c>();
         **List<Incident__c> lst_selected_check = new List<Incident__c>();//only stores those records for which check box is checked.** 

         public PageReference doInsert() {

            Incident__c objdlt = new Incident__c();   

           if(impact){ 
              objdlt.impact__c=impact ;
            }       

            if(incident_state){
               objdlt.incident_state__c=incident_state;
            }

            if(short_description){
               objdlt.short_description__c=short_description;
            }

            if(contact_type){
               objdlt.contact_type__c=contact_type;
            }

            insert objdlt; 
            **//check either one of your checkbox is checked then add to the list
            Schema.DescribeSObjectResult objSchema = Incident__c.sObjectType.getDescribe();
            Map<String, Schema.SObjectField> fieldMap = objSchema.fields.getMap();
            Set<String> fields = new Set<String>(); 
            for (String fieldName : fieldMap.keySet()){
                SObjectField sfield = fieldMap.get(fieldName);
                schema.describefieldresult dfield = sfield.getDescribe();
                if(objdlt.get(fieldName) == true) {
                    if(dfield.isCustom() && String.valueOf(dfield.getSoapType()) == 'Boolean') {
                        lst_selected_check.add(objdlt);     
                    }  
                }
            }**         
            lst.add(objdlt);

         }      
    }

i think this will solve your purpose.
