Hi Abhishek,

As Raj said, you need to use two soql queries to fetch users in the Queue.

Use the following queries:
 [Select Id from Group where type='Queue' and Name='Queue Name'];
[Select UserOrGroupId From GroupMember where GroupId =:IdOfAboveQuery];

Hi Raj and Sowmya,

The issue with the Query provided is you cannot directly extract the users if the Queue contains Roles and Subordinate / Roles and Internal Subordinates.
/* Select UserOrGroupId From GroupMember where GroupId =:IdOfAboveQuery */
This(above) Query will not work if Queue has Roles and Subordinate added as a group in Queue. I think we need to firstly fetch the Role ID from the UserRole Object and then Query the User object with the provided roleId.

/*select Id from UserRole where ParentRoleId IN :roleIds AND ParentRoleID != null */
Please correct me if i'm Wrong.

I got a code from one of the blog posts as under.
public static Set<id> GetUserIdsFromGroup(Set<Id> groupIds)
        // store the results in a set so we don't get duplicates
        Set<Id> result=new Set<Id>();
        String userType = Schema.SObjectType.User.getKeyPrefix(); //005
        String groupType = Schema.SObjectType.Group.getKeyPrefix(); //00G
        Set<Id> groupIdProxys = new Set<Id>();
        // Loop through all group members in a group
        for(GroupMember m : [Select Id, UserOrGroupId, Group.Type, Group.RelatedId From GroupMember Where GroupId in :groupIds])
            // If the user or group id is a user
            // If the user or group id is a group
            // Note: there may be a problem with governor limits if this is called too many times
            else if (((String)m.UserOrGroupId).startsWith(groupType))
                // Call this function again but pass in the group found within this group
        if(groupIdProxys.size() > 0)
            Set<id> groupId = new set<id>();
            Set<id> roleId = new set<id>();
            Set<id> roleAndSubId = new set<Id>();

            for(Group g2 : [Select Id, Type, relatedId From Group Where Id = :groupIdProxys]){
                if(g2.Type == 'Role'){  
                else if(g2.Type== 'RoleAndSubordinates'){ 
                else if(g2.Type== 'PRMOrganization'){        
                else if(g2.Type== 'Regular'){
                for(User u: [select id from user where UserRoleId IN: roleId]){
                for(GroupMember gm : [select id, UserOrGroupId from GroupMember where GroupId IN: groupId]){
        return result;  
    public static Set<ID> getAllSubRoleIds(Set<ID> roleIds) {
        Set<ID> currentRoleIds = new Set<ID>();
        // get all of the roles underneath the passed roles
        for(UserRole userRole :[select Id from UserRole where ParentRoleId IN :roleIds AND ParentRoleID != null limit 40000])
        // go fetch some more rolls!
        if(currentRoleIds.size() > 0)
        return currentRoleIds;
