T-SQL - DELETE Keyword



The T-SQL (Transact-SQL) DELETE keyword is used to delete the existing records from a table. A WHERE clause can be used with the DELETE statement to delete the selected rows, otherwise all records will be deleted.

Syntax

The syntax for using DELETE keyword in T-SQL (Transact-SQL) is given below:

DELETE table_name
WHERE condition(s);

Example:

Consider a database containing a table called Employee with the following records:

EmpIDNameCityAgeSalary
1JohnLondon253000
2MarryNew York242750
3JoParis272800
4KimAmsterdam303100
5RameshNew Delhi283000
6HuangBeijing282800

  • To delete the records of an employee whose EmpID is 5, the statement is given below:

    DELETE FROM Employee
    WHERE EmpID = 5;
    
    --See the result
    SELECT * FROM Employee
    

    Now the Employee table will contain following records:

    EmpIDNameCityAgeSalary
    1JohnLondon253000
    2MarryNew York242750
    3JoParis272800
    4KimAmsterdam303100
    6HuangBeijing282800
  • Similarly, to delete the records of an employee where city starts with 'New', the statement will be:

    DELETE FROM Employee
    WHERE City LIKE 'New%';
    
    -- see the result
    SELECT * from Employee;
    

    Now the Employee table will contain following records:

    EmpIDNameCityAgeSalary
    1JohnLondon253000
    3JoParis272800
    4KimAmsterdam303100
    6HuangBeijing282800
