SQL Server, if the data is mistakenly deleted, according to the official statement, SQL Server is not undelete. To save the deleted data, the most typical way is to restore the data from another DB and then add it back to the formal db by restoring the backup file to another db.However, if the transaction log structure of SQL Server is known to the person, as long as the transaction record is still, you can parse the transaction record to obtain the d

SCO OpenServer supports versioning filesystems (undelete), but the default does not turn on this feature, the following are the specifics:
1) Select Hardware/kernel Manager in Scoadmin, select filesystem configuration,
Set Maxvdepth to a value other than 0 (n= How many previous versions are saved, consider disk space when setting a larger number)
Set Minvtime (number of seconds to wait before file versioned)
2) Recompile (relink) kernel;
3 Reboot

The company is using partition online. The partition field of a table is incorrect and needs to be rebuilt. It turns out that there is no way to directly fix it using an SQL statement like modifying the primary key field or index field. Instead, you need to create a temporary table with a down time. So I carefully read the document and studied the details of partition

For a hard disk, the possible number of bytes in a sector is 128 x 2n (n = ). In most cases, take n = 2, that is, the size of a single sector (sector) is 512 bytes. In the master boot records of a total of 446 bytes, the MBR boot program occupies the first bytes (offset 0 h ~ Offset 1bdh), followed by 64 byte
