What Is Data Manipulation Language (DML)?

Data manipulation languages are the best. We use them to manipulate data in a database, which is probably why they're called "data manipulation languages." They allow us to do all kinds of things with our data, like inserting it into tables, retrieving it from existing tables and deleting it from existing tables. That's not even everything! We can also modify existing data in various ways. There are a lot of different DMLs out there, but the most popular DML is SQL, which stands for "Structured Query Language." SQL is used for managing databases, where we store all of our data. SQL is a language used to write queries and updates to databases. Its most common form is Structured Query Language, or "SQL." DML stands for Data Manipulation Language, a subset of SQL that allows you to manipulate data in a database. The DML language is designed to resemble simple English, making it easier for users to interact with the system. The functional capability of DML is organized in manipulation commands like SELECT, UPDATE, INSERT INTO and DELETE FROM. These are described below: SELECT: This command retrieves rows from a table. The syntax is SELECT [column name(s)] from [table name] where [conditions]. SELECT is the most widely used DML command in SQL. UPDATE: This command modifies the data of one or more records. An update command syntax is an UPDATE [table name] SET [column name = value] where [condition]. INSERT: This command adds one or more records to a database table. The insert command syntax is INSERT INTO [table name] [column(s)] VALUES [value(s)]. DELETE: This command removes one or more records from a table according to specified conditions. Delete command syntax Imagine you're a user. You've just signed up for an app and submitted your basic details. Now, all that data needs to be inserted into a specified table so that every registered user can have their own entry. When you log in to the app, all your information will be displayed in your profile page. You can then perform operations on your profile, like inserting, deleting, or retrieving data according to your preferences. These operations are handled by DML commands, which are frequently used by end users and allow them to interact with the system. In order to provide users with maximum convenience, DML commands also offer various facilities such as WHERE HAVING clauses and GROUP BY statements along with SQL commands.
