That's a nice UPDATE statement you've got there...
Would be a shame if it were to be executed...
Without a WHERE clause 
Nothing serious, but still a PITA.
I was about to delete that statement, but hit F5 instead of backspace

Been there, done that. Nothing quite as unnerving as seeing 847 rows affected when you only expected 1. Fortunately it was something like adding a quantity of 5 to an existing value, so I could just reverse it.

Whenever doing insert\update\delete I always write the WHERE clause first 
|
|
|
|
|
INSERT ... WHERE ...
Interesting.
Do you get a lot of success with that?

Interesting, I always write my insert/update/delete statements with a WHERE 1=0 clause first, so even if I have a moment of sheer stupid and run it, chances are less likely it will work. After that, I add AND then the actual clause.
Trying to get people around here to wrap their insert/update/deletes in a rollback/commit block is like pulling teeth. Seriously, what do you expect the change to be? If it doesn't match that something went wrong.

I did, but I wanted to change the UPDATE Table... to SELECT * FROM TABLE... So I highlighted the query without the WHERE clause and wanted to delete it... With F5

ditto. But when using MySql (which I do for about 50% of my projects, Sql Server the other 50%) I usually use MySql Workbench; this has an option ("Safe updates") that prevents execution of update queries without a where clause. (Though it accepts WHERE 1=1 for when you really want to update everything).

Couple of weeks ago, but, as they used to say: "saved by the skin of my teeth"
Was working on code that produces SQL par rowsets by interpreting SQL table schema. Anyway, I was working on a version of the table that was named the same, but with an _test. I wanted to clear it of data, except the first record. DELETE FROM and then the moment of horror. My _test table wasn't empty. The production table was. Literally hundreds of reports and dozens of applications are totally dependent upon this table.
But, as it would happen, somehow a miracle was pre-planned. Literally the night before, my boss created an archive table. All the deleted records were moved to it. The several minutes of horror were soothed with a little bit of delete, rename, and then recreating that archive . . . just in case I want to drive myself to drink again, some day.* Amazingly, quick enough (although it seemed to take forever) that no one even called IT or put in a support request.
* Yes, there are backups, but until that could be brought to bare, a major panic was imminent, much yelling, screaming, gnashing of teeth, and then the bad stuff would start.
** This is only the second time in about 15 years I popped a production table. It was all much less essential that first time.

With some equipment[^] you get no second chance.

We had something like that hanging right above those consoles:

I wrote an SQL-Generator for that, so every DB Model has it and the Generator creates the statements. This saves my a55

Unless selecting, always start your SQL script with "START TRANSACTION".

That's like jumping out of a plane with a parachute on, just in case you need it. Real men don't need it.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

My rule of thumb is to create the select statement and run it before changing it to delete or update. That, however, only works if (1) I count on my thumbes, and (2) type the write table name. Everything could seem OK. (even with your Transaction wrap) until just a little bit later.

It is not relevant how things seem.
You validate before you commit. You cannot assume, one must validate. Seriously, paranoia pays.

Yeah, I usually do this.
Of course that doesn't work when you have some text selected (which I had) for deletion, but hit F5 instead 
Luckily we had a backup (well, not so lucky as we make those daily) and I was able to undo the harm without anyone even reporting the issue

Easy mistake, since the F5 key is right next to the Del key ... oh wait.
Been there and done that, though. The feeling when you just realize you've just deleted the whole company's timecard entries? Like jumping out of an airplane. Thank goodness for frequent (15-minute intervals) log backups.
If you think 'goto' is evil, try writing an Assembly program without JMP.
