Hi I am working on the scenario, and need some help from the community, kindly help me out for the below .
I have created a below map in my class : -
Private Map <Id, string> testMap = new Map <Id, string>();
and i am populating the the map as below with the key and value pair,
for(Test_obj__c sId : listOfObject){
testMap .put(sId.id, sId.TextField);
}
Values in the above field as below, printed with the help of system.debug;
]|DEBUG|>>>>>>>>>Required Map as follows in batch in Execute Method==
{a1f3M000000aSCYQUA3=TestValueA, a1f3M000000aSD7Q8M=TestValue4
}
Question or help needed:-- I need to query all the records as per the Key as Id and Update on particular field in the data base, for example:- a1f3M000000aSCYQUA3--Stored as (sourcetestFiled) with this ID if i have got the 4 records then i need to update the particular field as TestValueA in for all the 4 record and update;
Similarly for the another ID (a1f3M000000aSD7Q8M)
I have done from below approach:-
for(id icId : testMap .keySet()){
for(Test_obj__c icToUpdate : [select id,TextField, textId__c from Test_obj__c Where textId__c =:icId]){
icToUpdate.TextField= testMap.get(icId);
listUpadte.add(icToUpdate);
}
}
Update List
I ahve done from the above approach, need some help to do it in the best possible way. thanks
