To find inside a hash MongoDB, you can use dot(.) notation. Let us first create a collection with documents> db.hashDemo.insertOne({"ClientName":"Larry", "ClientAge":23, "ClientDetails":{ "isEducated": true, "ClientProject" : "University Management"}}); { "acknowledged" : true, "insertedId" : ObjectId("5ca1ef1266324ffac2a7dc5e") } > db.hashDemo.insertOne({"ClientName":"Chris", "ClientAge":26, "ClientDetails":{ "isEducated":false, "ClientProject" : "Online Book Store"}}); { "acknowledged" : true, "insertedId" : ObjectId("5ca1ef7766324ffac2a7dc5f") }Following is the query to display all documents from a collection with the help of find() method> db.hashDemo.find().pretty();This will produce the following output{ "_id" : ObjectId("5ca1ef1266324ffac2a7dc5e"), "ClientName" : "Larry", "ClientAge" : 23, "ClientDetails" : { "isEducated" ...

To get the names beginning with a particular character, you need to use LIKE. Let us first create a table:mysql> create table DemoTable ( StudentFirstName varchar(20) ); Query OK, 0 rows affected (1.01 sec)Following is the query to insert some records in the table using insert command:mysql> insert into DemoTable values('John'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('Carol'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('Johnny'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('Robert'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values('Chris'); ...

Ozone is measured as Dobson units. And a Dobson unit of gas is equal to a layer of gas, with a thickness of one-hundredth of a millimeter at the surface of the Earth. The ozone in the atmosphere is measured by about 300 Dobsons.Ozone is also known as a trace gas, meaning there are very few amounts in the atmosphere. In fact, it is concluded that out of every million molecules of gas in the atmosphere, less than ten are ozone. Though it does not sound or seems like much, it's enough to protect you from the Sun's UV rays.The ... Read More
In this program we will see how to subtract two 16-bit BCD numbers.Problem StatementWrite 8086 Assembly language program to subtract two 16-bit BCD numbers stored in memory offset 500H – 501H and 502H – 503H.DiscussionHere we are adding the 16-bit data byte by byte. At first we are subtracting lower byte and perform the DAS instruction, then Subtract higher bytes with borrow, and again DAS to adjust. The final result is stored at location offset 600H, and if borrow is present, it will be stored at 601H.We are taking two numbers 8523 - 7496 = 1027InputAddressData……50023501855029650374…… Flow Diagram Program OutputAddressData……600276011060200……
