DDL commands i.e ALTER, RENAME, TRUNCATE
ADD and DROP a Constraint using ALTER TABLE command in SQL In this class, we will understand ADD and DROP a Constraint using ALTER TABLE command in SQL. We have already discussed the concepts of ADD, DROP, and MODIFY columns of a table. ADD and DROP a Constraint using ALTER TABLE command in SQL This class will understand how to ADD and DROP a Constraint using ALTER TABLE command in SQL. To understand, we will consider the user’s table as shown below. The above is what we have considered in our previous class. We haven’t created a primary key for the user’s table. We will now alter the table by adding the id column as the primary key. ADD Constraint ALTER TABLE users ADD CONSTRAINT pk_users PRIMARY KEY (id); In the above command, ADD CONSTRAINT is the keyword used to add a constraint. Whenever we add a constraint, we have to give the name of the ‘constraint.’ In our case, we have given the name pk_users. These names are significant because they are used in the future to change the constraints. The new constraint has been added. To check whether the constraint has been altered, let us insert the row as shown below. DROP Constraint ALTER TABLE users DROP CONSTRAINT pk_users; The DROP CONSTRAINT is the keyword used to drop the constraint. In the above command, the constraint name has been used. By executing the above command, the primary key constraint will get dropped. To check whether the constraint has been dropped or not, we will insert the row as shown below. Even though the id value exists in the id column, the row will get inserted. #learningmonkey #dbms #placements #gatecse #gatedbms #campusplacements Link for playlists: 🤍 Link for our website: 🤍 Follow us on Facebook 🤍 🤍 Follow us on Instagram 🤍 🤍 Follow us on Twitter 🤍 🤍 Mail us 🤍 learningmonkey01🤍gmail.com
Data Definition Language is a set of 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. Here are some examples of DDL commands in SQL: CREATE: This command is used to create a new database or object (such as a table, index, or view) in the database. ALTER: This command is used to modify the structure of an existing database object. For example: DROP: This command is used to delete an entire database or an object (such as a table, index, or view) from the database. For example: TRUNCATE: This command is used to delete all the data from a table, but not the table structure itself. For example: RENAME: This command is used to rename a database object

Learn how to insert Data into Tables using INSERT Statement in SQL Server. To insert values to all columns of a Table, there is no need to specify column names. Just put the values for each column in a sequence as they appear in the table. If you change the sequence, the number of values, or the data type, it may lead to incorrect data. Use SELECT * from TABLE query to display the inserted data. Music by Commoninterest - Oblivion - 🤍 #shorts#SQLInsert#msSql
