explain the all types of commands. off DDl and DML
Here is your Answer:-
DDL Commands:- DDL means Data Definition Language. It is used to create and modify the structure of database objects in SQL.
DML Command:- DML Command in SQL database stands for Data Manipulation Language. DML commands are used to retrieve, store, Modify, delete, insert and update data in database.
Answer:
Structured Query Language(SQL) as we all know is the database language by the use of which we can perform certain operations on the existing database and also we can use this language to create a database. SQL uses certain commands like Create, Drop, Insert, etc. to carry out the required tasks.
These SQL commands are mainly categorized into four categories as:
DDL – Data Definition Language
DDL – Data Definition LanguageDQl – Data Query Language
DDL – Data Definition LanguageDQl – Data Query LanguageDML – Data Manipulation Language
DDL – Data Definition LanguageDQl – Data Query LanguageDML – Data Manipulation LanguageDCL – Data Control Language
Though many resources claim there to be another category of SQL clauses TCL – Transaction Control Language. So we will see in detail about TCL as well.
DDL (Data Definition Language):
DDL or Data Definition Language actually consists of the SQL commands that can be used to define the database schema. It simply deals with descriptions of the database schema and is used to create and modify the structure of database objects in the database.DDL is a set of SQL commands used to create, modify, and delete database structures but not data. These commands are normally not used by a general user, who should be accessing the database via an application.
List of DDL commands:
CREATE: This command is used to create the database or its objects (like table, index, function, views, store procedure, and triggers).
DROP: This command is used to delete objects from the database.
ALTER: This is used to alter the structure of the database.
TRUNCATE: This is used to remove all records from a table, including all spaces allocated for the records are removed.
COMMENT: This is used to add comments to the data dictionary.
RENAME: This is used to rename an object existing in the database.
DQL (Data Query Language):
DQL statements are used for performing queries on the data within schema objects. The purpose of the DQL Command is to get some schema relation based on the query passed to it. We can define DQL as follows it is a component of SQL statement that allows getting data from the database and imposing order upon it. It includes the SELECT statement. This command allows getting the data out of the database to perform operations with it. When a SELECT is fired against a table or tables the result is compiled into a further temporary table, which is displayed or perhaps received by the program i.e. a front-end.
List of DQL:
SELECT: It is used to retrieve data from the database.
DML(Data Manipulation Language):
The SQL commands that deals with the manipulation of data present in the database belong to DML or Data Manipulation Language and this includes most of the SQL statements. It is the component of the SQL statement that controls access to data and to the database. Basically, DCL statements are grouped with DML statements.
List of DML commands:
INSERT : It is used to insert data into a table.
UPDATE: It is used to update existing data within a table.
DELETE : It is used to delete records from a database table.
LOCK: Table control concurrency.
CALL: Call a PL/SQL or JAVA subprogram.
EXPLAIN PLAN: It describes the access path to data.
DCL (Data Control Language):
DCL includes commands such as GRANT and REVOKE which mainly deal with the rights, permissions, and other controls of the database system.
List of DCL commands:
GRANT: This command gives users access privileges to the database.
REVOKE: This command withdraws the user’s access privileges given by using the GRANT command.
Though many resources claim there to be another category of SQL clauses TCL – Transaction Control Language. So we will see in detail about TCL as well. TCL commands deal with the transaction within the database.
List of TCL commands:
COMMIT: Commits a Transaction.
ROLLBACK: Rollbacks a transaction in case of any error occurs.
SAVEPOINT:Sets a savepoint within a transaction.
SET TRANSACTION: Specify characteristics for the transaction.

1*2; C2 7+A6-5; undefined (5*3)-8; D2 9/3; C1 7+10-9+8; undefinedIgnore the non-bold values because they are there to number each problem 1 through 5 (rather than be part of the numeric answers).
=======================================================
Explanation:
Problem 1
The notation =C3*C2 means we multiply the numbers in cells C3 and C2. A cell like C3 means we look at column C and row 3. The value 1 is in cell C3. The value 2 is in C2. Therefore =C3*C2 becomes 1*2 = 2. The result 2 is in cell C2.
----------------------
Problem 2
According to the table:
D2 = 7A6 = undefinedD1 = 5I mentioned A6 is undefined because the table only goes to row 3, and not row 6. I'm not sure if this is a typo or intentional. Since A6 is undefined, the result of =D2+A6-D1 is also undefined.
----------------------
Problem 3
The table shows
D1 = 5C1 = 3B3 = 8So, =(D1*C1) - B3 becomes (5*3)-8 and that fully simplifies to 7, which is found in cell D2.
----------------------
Problem 4
We have
D3 = 9C1 = 3Therefore, =D3/C1 = 9/3 = 3 which is found in cell C1
----------------------
Problem 5
D2 = 7B1 = 10D3 = 9B3 = 8So,
=D2+B1-D3+B3 = 7+10-9+8 = 16
which unfortunately is not found in any of the cells of the table.
The location of 16 is undefined.
