SQLite DELETE Query is used to delete the existing records from a table. You can use WHERE clause with DELETE query to delete the selected rows, otherwise all the records would be deleted.

Syntax

Following is the basic syntax of DELETE query with WHERE clause.

DELETE FROM table_name
WHERE [condition];

You can combine N number of conditions using AND or OR operators.

Example

Consider COMPANY table with the following records.

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
1           Paul        32          California  20000.0
2           Allen       25          Texas       15000.0
3           Teddy       23          Norway      20000.0
4           Mark        25          Rich-Mond   65000.0
5           David       27          Texas       85000.0
6           Kim         22          South-Hall  45000.0
7           James       24          Houston     10000.0

Following is an example, which will DELETE a customer whose ID is 7.

sqlite> DELETE FROM COMPANY WHERE ID = 7;

Now COMPANY table will have the following records.

ID          NAME        AGE         ADDRESS     SALARY
----------  ----------  ----------  ----------  ----------
1           Paul        32          California  20000.0
2           Allen       25          Texas       15000.0
3           Teddy       23          Norway      20000.0
4           Mark        25          Rich-Mond   65000.0
5           David       27          Texas       85000.0
6           Kim         22          South-Hall  45000.0

If you want to DELETE all the records from COMPANY table, you do not need to use WHERE clause with DELETE query, which will be as follows −

sqlite> DELETE FROM COMPANY;

Now, COMPANY table does not have any record as all the records have been deleted by DELETE statement.
