SQL tutorial-Delete data

Delete data



To delete data from a table you can use the DELETE statement
The DELETE statement has the following syntax:

DELETE FROM Table-name

[WHERE...];


Example: Delete all student's records that don't have Address.

TblStudent table:

StuID StuName Sex DOB Address Tel
S001Sao VirakF 12-02-1982 #234, st. 230, Phnom Penh 0897654678
S002Sok LidaM 03-06-1984 Chambak Bati Tramkna 092767896
S003Cheng SokunF 09-09-1987   090543123

DELETE FROM TblStudent

WHERE Address IS NULL or Address='';

Note: Without WHERE clause, you will delete all rows of the table
