How do I delete data using the primary key in SQL Server?

Question

Working on a small database project, and one of the requirements is to show how to delete data using the primary key. The exact statement is

• Show one delete statement that use a primary key to delete data

However, I can't figure out what the exact syntax for that would be. Could anyone show me a quick example?

Answer 1

That's a basic delete statement . Assuming table mytable and primary key id :

delete from mytable where id = 1

Answer 2

Use the WHERE clause In the delete statement to specify the conditions used to limit the number of rows that are deleted. For example, WHERE column_name = value. If a WHERE clause is not supplied, DELETE removes all the rows from the table.

Answer 3

DELETE FROM table_name WHERE condition;

for example:

table name= person

enter image description here

DELETE FROM persons WHERE id > 3;

deleted items which had id>3 and return me:
