If you are a Database designer or Database Maintainer or maybe working with the Database then you already know, what is the importance of the Database? Nowadays if you want to store the data at that time you need the database.
What is Database?
The database is nothing without the data. It is a place where data are stored. If you have any website or android application or desktop application and you want to store the user data or any type of data then you need the Database.
The database is of two types first offline database which allows storing the data in a local system means If the data are stored in a computer we can’t access these data from another computer or mobile.

Now, let’s discuss the DML in this article.
What is DML?
The DML full form is Data Manipulation Language. It is a type of SQL command which allows performing all work related to manipulation of the data stored in the database.
The work is like insertion, Updation, Deletion of the data into the database. This command is useful only to manipulate the Data. It is not used to change the structure of the database.
This command is the most useful command in SQL because without DML commands the data is not inserted, deleted and updated into the database.
What is the DML commands?
DML offers lots of commands to perform lots of work. The DML commands are used to insert data into the database table, Delete the data, and Update the data into the database table.
The DML commands are not auto-committed. It means the changes using DML commands are note saved permanent into the database, it can be rolled back. While the DDL commands are auto-committed.
Below the list of DML commands are written, they are as follows:
- SELECT Command
- INSERT Command
- DELETE Command
- UPDATE Command
Note: The DML commands are not case sensitive. You can use either in capital letters or in small letters. But I recommend using all command in capital letters.
1) SELECT Command:
The DML SELECT Command is useful to fetch the data from the existing database table. It means this command is used to select the data from the table. We can use SELECT Command with WHERE Clause to select the data according to the conditions.
Syntax of SELECT Command to select the data from the table:
SELECT col1, col2,… FROM TableName
Syntax of SELECT Command to select the data from the table with WHERE clause:
SELECT col1, col2,… FROM TableName WHERE condition
2) INSERT Command:
The DML INSERT Command is used to insert the data into the existing database Table. This is one of the important commands in SQL and also a useful command.
Syntax of INSERT Command to insert the data:
INSERT INTO TableName (Col1, Col2, Col3,…..) VALUES (Value1, Value2, Value3…)
3) DELETE Command:
The DELETE command is used to delete the data from the database table. This command is also used with WHERE Clause to delete the data according to the condition.
Syntax of DELETE Command to delete the data:
DELETE FROM TableName WHERE condition
Note: This command is used to delete only the data, not the table or another database object. If you want to delete the table from the database you can use the DROP Command.
4) UPDATE Command:
The UPDATE command is used to update the data of the database table. This command is used to update only the data not the structure of the database object. If you want to change the structure of the database object you can use ALTER command.
Syntax of the UPDATE command:
UPDATE TableName SET column1=val2, col2=val2 ,…. WHERE condition;
Note: The UPDATE command always used with WHERE clause. Without WHERE clause this command updates all the data stores in the table.

For example, in the database, each work is completed with the help of queries.
