INSERT INTO [database_name].[dbo].[table_name]
(column1, column2, ... )
VALUES
(expression1, expression2, ... ),
(expression1, expression2, ... ),
...;

Example:

Insert some records in “STUDENT” table:

INSERT INTO [tecklearn].[dbo].[STUDENT]
([ID],[NAME]
,[AGE],[SALARY])
VALUES(1,'Ajeet',27,20000),
(2,'Backon',29,28000),
(3,'Chris',17,25000);

You can directly use the above command during a New Query or follow the management studio screenshots given below:

View Inserted Data:

Output:

You can see that each one three records are inserted now within the “Student” table.

SQL Server Update Data

In SQL Server database, UPDATE statement is employed to update or modify the already inserted records into a table.

Syntax:

UPDATE [tecklearn].[dbo].[STUDENT]
SET [ID] =
,[NAME] =
,[AGE] =
,[SALARY] =
WHERE GO

Use the SQL Server management Studio:

Follow the management studio screenshots given below:

After clicking on “New Query Editor Window”, you’ll see the subsequent query page.

Use the subsequent command:

UPDATE [tecklearn].[dbo].[STUDENT]
SET [ID] = 4,[NAME] = 'Malvika',[AGE] = 18,[SALARY] = 22000
WHERE ID =2;
GO

You can see that 1 row is affected. you’ll verify it:

Output:

You can see that the above records are now updated.

SQL Server DELETE Data

In SQL Server database, DELETE statement is employed to delete records from the table.

Syntax:

SELECT TOP 1000 [ID]
,[NAME],[AGE],[SALARY]
FROM [tecklearn].[dbo].[STUDENT]

Use the SQL Server management Studio:

Follow the management studio screenshots given below:

Use the subsequent command:

DELETE FROM [tecklearn].[dbo].[STUDENT]
WHERE ID =3;

Here one row is deleted where ID=3. you’ll verify it:

Output:

SQL Server DELETE Top Statement

In SQL Server, DELETE TOP statement is employed to delete the records from a table and limit the amount of records deleted regarding a hard and fast value or percentage.

Syntax:

DELETE TOP (top_value) [ PERCENT ]
FROM [database_name].[dbo].[table_name]
[WHERE conditions];

Parameter explanation

table: It specifies a table that you simply want to delete records from.

WHERE conditions: it’s optional. The conditions that has got to be met for the records to be deleted.

TOP (top_value): it’s wont to delete the highest number of rows within the result set supported top_value. for instance , TOP(10) would delete the highest 10 rows matching the delete criteria.

PERCENT: it’s optional. it’s wont to delete the share of of top rows. for instance , TOP(10) PERCENT would delete the highest 10% of the records matching the delete criteria.

DELETE using TOP keyword

TOP keyword is employed with DELETE statement to delete the required top rows of a table.

Example:

We have a table “Employees”, having the subsequent data.

Delete top 2 rows from the table “Employees” where salary is bigger than or adequate to 20000.

Syntax:

DELETE TOP(2)
FROM [tecklearn].[dbo].[Employees]
WHERE salary >= 20000;

You can see that 2 rows are affected. Now see the output:

Output:

DELETE using TOP Percent Keyword

TOP percent keyword is employed to delete the rows consistent with the share .

Example:

Delete TOP 25% rows from the table where salary is bigger than 20000.

DELETE TOP(25) PERCENT
FROM [tecklearn].[dbo].[Employees]
WHERE salary > 20000;

You can see that 3 rows are affected. 3 is strictly 25% of 12 which is that the number of inserted rows.

Output:
