Sheesh, you just reminded me of my dumb DBA trick that actually occurred in SQL Server 9 years ago- Someone had removed the "WHERE USERID =XXXXX " clause from a 30 line login/user cleanup script for a SQL Server system and the last statement just issued- DELETE FROM SYSUSERS
I pretty much stopped breathing as I watched the final results on the screen: 1 row deleted.
1 row deleted.
1 row deleted
1659 rows deleted.
Microsoft said, "Yeah, start restoring, we can't help you..." 36 hrs later everyone was back in and working... That script became a stored proc that very day! :)

When copying and pasting delete and update statements into sqlplus put them on a single line if possible to avoid the possibility of missing the where clause.

Well, I always use a script to place the database name into the sql prompt. Making changes on the wrong database can ruin your whole day (or life).
So you need "do's" and "don'ts"

Compiling a list of major blunders to avoid:
Don't use the number 8 for scripting or ORACLE_SID due to the wild card
character * above it.
Don't use rm *.*
....
Anyone else have some to contribute?
thanks
