How to query data which was modified in specific time limit in Salesforce?

Below is the SOQL to query data which was modified between 8 PM and 10 PM.

Sample SOQL:

SELECT Id, LastModifiedDate FROM Contact WHERE LastModifiedDate = TODAY AND HOUR_IN_DAY(LastModifiedDate) >= 20 AND HOUR_IN_DAY(LastModifiedDate) < 22

Accessing keys from a map in a SOQL Query

Using .KeySet() on a map, we will get a list of all the keys returned.

Map<Id, Master_Obj__c> masterMap = new Map<Id, Master_Obj__c>([SELECT Id, Name FROM Master_Obj__c]);
List<Detail_Obj__c> objDetailList = [Select Id, Name FROM Detail_Obj__c WHERE Master_Obj__c IN :masterMap.KeySet()]

Displaying records based on the picklist values

Here is the example of Opportunity object, based on Stage Picklist values.

Apex Class:

public class SearchOpportunity {
    public Opportunity opp  {get;set;}
    public List<Opportunity> OpportunityList  {get;set;}
    public SearchOpportunity () {
        opp = new Opportunity();
    public PageReference doSearch() {
        OpportunityList =[Select Id, Name, StageName FROM Opportunity WHERE StageName =: Opp.StageName];
        return null;

Visualforce Page:

<apex:page controller="SearchOpportunity">
        <apex:pageBlock Title="Search Opportunities">
            <b>Stage :</b>
            <apex:inputField value="{!opp.StageName}" />
            <apex:commandButton value="Search" action="{!doSearch}"/>
        <apex:pageBlock title="List of Opportunities">
            <apex:pageBlockSection columns="1">
                <apex:pageBlockTable value="{!OpportunityList}" var="item">
                    <apex:column value="{!item.Name}" headerValue="Name"/>
                    <apex:column value="{!item.StageName}" headerValue="Stage"/>
