MariaDB Error 1752: Unrollbackable Temp Table Drops
Description
This error indicates that during a database transaction, temporary tables were created and subsequently dropped. However, due to the non-transactional nature of dropping temporary tables, these specific operations cannot be undone if the transaction later fails and needs to be rolled back. This means the database state concerning temporary tables will not be fully restored to its pre-transaction state.
Error Message
Some temporary tables were dropped, but these operations could not be rolled back.
Known Causes
4 known causesNon-Transactional Nature of Temp Table DDL
Operations like `DROP TEMPORARY TABLE` are often implicitly committed or not fully reversible within a transaction, making them unrollbackable.
Rollback After Temp Table Drop
An explicit transaction included creating and dropping a temporary table, and then an error or `ROLLBACK` command was issued, attempting to undo the drop.
Session-Specific Table Management
Temporary tables exist only for the duration of a session. Once dropped, their state cannot be restored from a global or persistent log during a rollback.
Application Logic Misconception
Application code might assume all operations within a transaction block, including temporary table DDL, are fully reversible, leading to this warning.
