Question

Ravi Vishwakarma · Answer

CRUD operations in 
SQL Server allow you to Create, Read, Update, and Delete data in your tables. Here’s how to perform each of these operations using SQL statements:
1. Create (Insert) Data
The INSERT statement is used to add new rows to a table.
Example: Inserting Data into CollageStudents
INSERT INTO CollageStudents (StudentID, FirstName, LastName, DOB, Address, IsSameAddress)
VALUES (5, 'Emily', 'Davis', '2003-02-12', '202 Birch St, City', 1);
2. Read (Select) Data
The SELECT statement is used to query and retrieve data from a table.
Example: Selecting Data from CollageStudents
SELECT * FROM CollageStudents
You can also use specific columns:
SELECT FirstName, LastName, Address FROM CollageStudents;
3. Update Data
The UPDATE statement is used to modify existing data in a table.
Example: Updating Data in CollageStudents
UPDATE CollageStudents
SET Address = '202 New Birch St, City', IsSameAddress = 0
WHERE StudentID = 5;
4. Delete Data
The DELETE statement is used to remove rows from a table.
Example: Deleting Data from CollageStudents
DELETE FROM CollageStudents
WHERE StudentID = 5;
and 
Summary
Create: Use the INSERT statement to add new rows.Read: Use the SELECT statement to query data.Update: Use the UPDATE statement to modify existing rows.Delete: Use the DELETE statement to remove rows.
