![]() ![]() Second, insert an address and a person into the addresses and people tables. ) Code language: SQL (Structured Query Language) ( sql ) And one address can be shared by multiple people.įirst, create the tables: CREATE TABLE IF NOT EXISTS people ( SQLite DROP TABLE statement examplesįor the demonstration purpose, we will create two tables: people and addresses. Therefore, you should perform the DROP TABLE statement with extra caution. You will not be able to undo or recover from this action. Notice that the DROP TABLE statement deletes the table from the database and the file on disk completely. If a foreign key constraint violation occurs, SQLite issues an error message and will not drop the table. If the foreign key constraints enabled and you perform the DROP TABLE statement, before SQLite performs the implicit DELETE statement, it carries the foreign key constraints check. However, the DROP TABLE statement removes the triggers associated with the table before performing the implicit DELETE statement, therefore, the delete triggers will not fire. The DROP TABLE statement performs an implicit DELETE statement before dropping the table. In case the table has dependent objects such as triggers and indexes, the DROP TABLE statement also removes all the dependent objects. If you want to remove a table in a specific database, you use the explicitly. If you use IF EXISTS option, then SQLite removes the table only if the table exists, otherwise, it just ignores the statement and does nothing. If you remove a non-existing table, SQLite issues an error. To remove multiple tables, you need to issue multiple DROP TABLE statements. SQLite allows you to drop only one table at a time. ![]() In this syntax, you specify the name of the table which you want to remove after the DROP TABLE keywords. The statement is simple as follows: DROP TABLE table_name Code language: SQL (Structured Query Language) ( sql ) To remove a table in a database, you use SQLite DROP TABLE statement. Introduction to SQLite DROP TABLE statement However unlike in other databases, when you perform such actions you will need to use 1 and 0 rather than TRUE and FALSE.Summary: in this tutorial, you will learn how to remove a table from the database using SQLite DROP TABLE statement. They can be created using the CREATE TABLE statement, and data can be inserted, retrieved, and manipulated using a variety of SQLite statements, such as SELECT, INSERT INTO, UPDATE, and DELETE. In conclusion, Boolean columns in SQLite are useful for storing data that has a binary nature. You can also use the DELETE statement to remove rows from the table where the value in the Boolean column is true or false. For example, you can use the UPDATE statement to change the value in a Boolean column from true to false or vice versa. In addition to using the SELECT statement to retrieve data from a Boolean column, you can also use it to manipulate the data. You can also use the SELECT statement to retrieve rows where the value in the Boolean column is false (represented by the integer 0). ![]() This would return all rows from the table where the value in the Boolean column is true (represented by the integer 1).
