Dear Friends
Inside the sql server how can I configure what will be registered inside the log file?
Thanks
Almir
Configure the recovery mode to Simple, Bulk-logged, or Full. See here.
but has how to choose what the sql server will write inside the log?
If you are asking about the transaction log - then you cannot modify what is written to that file, nor would you want to modify it as it is required to maintain database consistency.
What is recorded to that file is the same in all recovery models unless the process meets the requirements for minimally logged transactions.
