SQL Server DBCC Commands: DBCC WRITEPAGE

DBCC WRITEPAGE is an undocumented and unsuported DBCC command in Microsoft SQL Server that can be used to write a page of data from a database to a specified file on disk. It can be used to troubleshoot issues with data corruption or to create a copy of a database page for further analysis.

To use DBCC WRITEPAGE, you must specify the database, file number, and page number of the page you want to write to disk. You must also specify the name of the file you want to create, as well as the name of the output device to write the data to.

Here is an example of how to use DBCC WRITEPAGE to write a page of data from a database to a file on disk:

-- Write page 100 of file 1 in the "MyDatabase" database to a file called "page100.dat"
DBCC WRITEPAGE ('MyDatabase', 1, 100, 'page100.dat', 'disk')

The output of DBCC WRITEPAGE will be a message indicating whether the operation was successful or not. If the operation was successful, the file “page100.dat” will contain the data from the specified page in the database.

It’s important to note that DBCC WRITEPAGE is a low-level operation that should be used with caution.
