Hi Vijay,

In your after insert trigger use the database.countQuery method to get the count of the dynamic SOQL, and check the no of record in Obect B.
 like below
integer count= database.countQuery('select count() from B');

if(count == 4){
// update records on Obj A


Hi Vijay ,
Here I have one question ,Is there any relationship between Obj A & Obj B .Or just you need to to check over all count of object B record ?
You have to write a trigger in Object A .Inside tthe trigger you can do a aggregate query to get the countof the record in Object B .
Integer recCountOfObjA=[SELECT count() FROM B];
However if you want the both object have relationship then logic will very if you want like each record needs to implement same logic .
Let us know so that we can help !!
