To delete the book named 'The Case of the Killer Kangaroo' from the database, you could use the following statements:Ĭ. Name='The Case of the Killer Kangaroo', author='Katie Kanga', O author='The Case of the Killer Kangaroo', name='Katie Kanga', Name='The Case of the Killer Kangaroo', author='Jane Doe', What values does the INSERT statement add to the Book table?Īuthor='The Case of the Killer Kangaroo', name='Jane Doe' O this program does not make sure the cursor object is closed Which statement makes sure that the cursor object is closed so its resources are released to the system? Which line opens the connection to the database? execute (query, (name, author, pages, genreID) ) ![]() Name = 'The Case of the Killer Kangaroo'Ĭ. This issue is an RFC for the best way to implement this feature.Conn = sqlite3. I've tried to implement this myself, both in LiipTestFixtures and in my own codebase by overriding the ORMSqliteDatabaseTool in the container but in both instances it's a lot harder than it needs to be, because the logic around enabling/disabling the checks in not extensible as a result of being declared private. Disable foreign key checks: PRAGMA foreign_keys = 0.Enable foreign key checks: PRAGMA foreign_keys = 1.Check if foreign key checks are enabled: PRAGMA foreign_keys.I'd like the ORMSqliteDatabaseTool to support disabling and enabling foreign key checks if you have them enabled in the first place.įrom the Sqlite docs, we can use the following queries: As such, when our Sqlite database is purged in test, foreign key checks are still enabled and it causes an exception. Looking at ORMDatabaseTool::cleanDatabase() we can see that foreign key checks are disabled before purging and enabled again afterwards, however this only happens for MySQL databases. We enable foreign key checks in a Symfony event listener shown in this stackoverflow question, which works great and has enabled us to catch quite a few issues in test before they make it to production. If you run MySQL in production and Sqlite in tests, you very likely want foreign key checks enabled, otherwise you will likely get errors in production which cannot be reproduced in tests. ![]() We manually enable foreign key checks on Sqlite for tests, which causes problems when loading fixtures because the foreign key checks are not disabled when purging the database as they are with MyQL.īy default, Sqlite has foreign key checks disabled and must be enabled at runtime if you want to enforce foreign key constraints. ![]()
