Dumb SQL questions

Right, my brain has shut down due to lack of sleep, so I really just want someone to tell me how to do this as I am clearly rubbish.

I have a load of part numbers in a table that should be AS1-..., unfortunately, some genius has been putting them in as ASI-...
How can I update the ASI- to AS1-?

UPDATE `table` SET `column`=REPLACE(`column`, 'ASI-', 'AS1-');

Isn't it something like:

Code:

update table_name 
     set row1 = "AS1-"
     where row1 = "ASI-"

I haven't done SQL for about three years now, though, so it could be wrong.

Yeah, this dawned on me after I'd posted. Done it now, thanks anyway.

Oh my god, yes, it's wrong.

(Although technically, that probably wouldn't have done anything

)

Every time I learn something new it pushes old stuff out of my brain.

I know the feeling, except it always pushes the useful stuff out, rather than all the pointless stuff that I can still remember.

To be fair, if the values were actually 'AS1-' rather than 'AS1-XXXXXXX', myp's answer would have been fine.

Hush, don't defend him.

Actually, I didn't even notice that. I just thought Joans was putting ellipses in to finish his sentences.

Yeah, but if that was the case, I shouldn't have needed to ask the question (although you might say I shouldn't have needed to anyway).
