On prod env:

  • drop table <important_table_here>;
  • update <table> set <sequential_field> = <constant_val>

Sounds like a good time to test your DB backups too!

Oh yeah, this happened to me once. Ran an update without a where clause, and in the moments after that, I had planned my exile to a remote village in Scotland.
Fortunately, I had run select before the update, and it was a small table so al the data was on the terminal.

SET AUTOCOMMIT=0; after that.
