Why do two SQLite :memory: connections see different tables?
KitForma editorial guide. A plain `:memory:` database belongs to its individual connection. Opening another connection creates another independent database.
Step-by-step answer
A plain
:memory: database belongs to its individual connection. Opening another connection creates another independent database.
Keep the intended connection alive for the test or use a documented shared-memory URI only when shared-cache semantics suit the application. Test table creation and lookup through each connection explicitly. Connection pools can accidentally create several empty databases when configured with plain :memory:. For realistic integration tests, a temporary file may better match production locking and connection behavior. An in-memory test does not verify filesystem durability, WAL handling or restart recovery.Sources and verification
