| every transaction is recorded in the log file, however they are not easy to decipher.Probably you'll need a delete trigger on the table. Any delete statement will cause the trigger to fire. You can log deleted information to a "log" table. |

provided you've a backup that covers the missing transactions also, you can restore it to get back transaction data.------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |

| Restore a backup taken before the data was deleted as a new database, copy the data over. There are log reader tools, they're not cheap and they're not guaranteed to get the data back unless DB is in full recovery (as log records may have been overwritten)--Gail ShawSQL Server MVP |

| Just in case clarification is needed:"Restore a backup" means:Restore a FULL backup, and all subsequent LOG backups, if necessary use "STOP AFTER" to restore to an exact point-in-time (just before the DELETE).Do this to a new, temporary, database.Then copy the accidentally-deleted rows from the Temporary-Database to the Original-DatabaseThis is not entirely straightforward as users may have re-added some of the "missing" records, and in recreating them they may have added them "differently". All those things can be resolved in the "recovery" of those rows, but it takes some thought to work out what to do for-the-best in such scenarios. |
