Create an account

Very important

  • To access the important data of the forums, you must be active in each forum and especially in the leaks and database leaks section, send data and after sending the data and activity, data and important content will be opened and visible for you.
  • You will only see chat messages from people who are at or below your level.
  • More than 500,000 database leaks and millions of account leaks are waiting for you, so access and view with more activity.
  • Many important data are inactive and inaccessible for you, so open them with activity. (This will be done automatically)

What's your #1 way to be careful with a live database?

#21
As an example, I create SQL like this


--Update P Set
--Select ID, Name as OldName,
Name='Jones'
From Person P
Where ID = 1000

I highlight the text from the end up to the Select and run that SQL. Once I verify that it is pulling the record I want to update, I hit shift-up to hightlight the Update statement and run that.

Note that I used an alias. I never update a table name explicity. I always use an alias.

If I do this in conjunction with transactions and rollback/commits, I am really, really safe.
