For an in-memory database, the only allowed journal modes are OFF and MEMORY. Are you trying to change the journal mode to WAL on an in-memory database? -- D.

Re: [sqlite] problem with journal_mode memory to wal
Hello, After reading more carefully the documentation I found that, but I want to create a db where I'm having just one writer and multiple readers, but I need that the readers never get db locked when they are reading so I thought using WAL journal_mode. But how can I create a WAL db? Many thanks, Vitor.

Then everything should work just fine for you. If you do not care about persistence, set PRAGMA synchronous=OFF. Many thanks, Vitor.
