SQL Commands or SQL Statements:

What is SQL Commands
What is SQL Commands

All the work performed in the SQL totally based on the commands. Commands are the statements that allow performing the specific task. The task may be to Create the Database and its Object, Delete the database, Insert data into Database, Update and Delete the data.

In other words, we can say that the command is a mediator between user and database because the user interacts with the database using the commands.

SQL has a couple of commands, which are divides based on the task like creation, insertion, updating, and deletion the data. It has mainly 5 commands they are as follows:

  1. DDL (Data Definition Language).
  2. DML (Data Manipulation Language).
  3. DCL (Data Control Language).
  4. TCL (Transaction Control Language)
  5. DQL (Data Query Language).

1) DDL Commands in SQL:

DDL stands for Data Definition Language. The DDL offers all the commands related to the structure of the database in its objects like Create a table, Delete a table, Alter the table, etc.

The DDL commands are auto committed. It means all the changes in the database are automatically committed. There is no need to granted in this command.

The list of DDL commands are as follows:

  • CREATE:- To create Database and it’s Objects such as Table, Index, etc.
  • ALTER:- It is used to change or modify the structure of the existing database and its objects such as change the name of the table, add or delete column into the Table. etc.
  • DROP:- The DROP command is useful when you want to delete the database and it’s objects with both structure and data. It means when you delete the table from the database, all the data are automatically deleted from that table.
  • TRUNCATE:- It is used to delete all the rows from the table. It means delete all the data from the table.

1) DML Commands in SQL:

The DML stands for Data Manipulation Language. This command is used to manipulate the data into the Database. In other words, we can say that it modify or change the database according to data, not structure.

The work is performed using these commands that are insertion, updation, and deletion of the data. The DML command is not auto-committed it means all the changes are not saved permanently into the database. It can be rollback.

The DML commands are as follows:-

  • INSERT:- It is used to insert the data into the database table. This is the most useful command in SQL.
  • UPDATE:- The UPDATE command is useful when you want to update the data into the table. This command is maximumly used with WHERE clause, without WHERE clause the entire table data will be updated. The WHERE clause enables to update of specific data in the table.
  •  DELETE:-  This command is useful when the user wants to delete the row of data from the table. We recommend using this command also with WHERE clause to delete specific data. Without WHERE clause all the data are deleted from the table.

3) DCL Commands in SQL:-

The DCL stands for Data Control Language. This command is used to grant permission to database users to access the data and also get back the permission from the users.

The DCL commands are as follows:-

  • GRANT:- The GRANT command is useful when you want to give permission to the users to access the database.
  • REVOKE:- This command is used to get back the permission from the database users.

4) TCL Commands in SQL:-

TCL stands for Transaction Control Language. This command is used to control the transaction. All the TCL commands are used only with the DML commands that is INSERT, DELETE, and UPDATE command.

The DML commands are not auto-committed so the TCL command is used with DML commands to commit and rollback the transactions.

TCL commands are as follows:-

  • COMMIT:- To save or commit all transactions or changes into the database.
  • ROLLBACK:- This command is used to undo all transactions from the database.
  • SAVEPOINTS:- The SAVEPOINTS command is similar to the ROLLBACK command. The ROLLBACK command undo all transactions, while AVEPOINTS command to undo a specific transaction not all. It means it undo the transactions to a certain point without affected the entire transactions.

5) DQL Commands in SQL:-

The DQL command Stands for Data Query Language. It has only one command which allows us to query or fetch the data from the database.

The DQL command is as follows:-

  • SELECT:- The SELECT command is used to fetch the data. The user can use the WHERE clause with the SELECT command to get specific data.
