In SQLite, DELETE query is used to delete the existing records from a table. You can use it with WHERE clause or without WHERE clause. WHERE clause is used to delete the specific records (selected rows), otherwise all the records would be deleted.
Syntax:
DELETE FROM table_name WHERE [conditions....................];;
Example:
We have an existing table named "STUDENT", having the following data:
Example1:
Delete the records of a student from "STUDENT" table where ID is 4.
DELETE FROM STUDENT WHERE ID = 4;
The student's record of id 4 is deleted; you can check it by using SELECT statement:
SELECT * FROM STUDENT;
Output:
Example2:
If you want to delete all records from the table, don't use WHERE clause.
DELETE FROM STUDENT;
You can see that there is no data in the table "STUDENT".
