Thanks, always nice to be reminded of the basics ...

If everything seems to be going well, you have obviously overlooked something.

I knew about the STR function, but was not entirely sure what the optional arguments meant, so I decided to check Books Online before answering.

I must say that I was a bit surprised to see an example that is EXACTLY identical to today's question...

Coincidence?

You cynic Hugo. 😛

But if the question serves to educate, test or whatever - I don't see the harm

I initially thought '23.45' as I would have thought the length requirement of 2 would 'count' from the smallest to the largest unit, but decided to test the statement before answering. I was surprised to get **, was not aware of this element of STR. An undeserved point for me, I think. Thanks for the question.

Note to developers:
CAST(SUBSTRING(CAST(FLOOR(NULLIF(ISNULL(COALESCE(1,NULL),NULL),NULL)) AS CHAR(1)),1,1) AS INT) == 1
So why complicate your code AND MAKE MY JOB HARDER??!:crazy:

Good question

But the explanation is very poor, inaccurate. For example the length of the expression "123.45" is 6, but str(123.45,4,2) is not '**' as suggested by the explanation but '123'.

Good thing that it is "**"

Wrong information is no information.

I don't think it is coincidence :hehe: but no problem as the question servers the purpose.

Other benefit is that the author of the question has an "exact" explaination available on msdn 😀

It is an exact copy from the http://msdn.microsoft.com/en-us/library/ms189527(v=sql.100).aspx, first example!

The examples on that page contain no explanations, so how can the explanation be an exact copy of something in one of them? Also, the length and decimal parameters are not the ones in the first example, but the ones in the second.

I guess the real point is that the length of '123.45' is irrelevant to whether '**' turns up, all that is relevant is the length of '123', since str is perfectly happy, if neccessary to get a result other than '**', to thow away everything after the decimal point and ignore the decimal argument of str. This is made absolutely clear by the text onm the page you refer to.

Incidentally, your link points to 'Microsoft Website': you have the display text and the URL the wrong way round. That makes it not a useful clickable link; doesn't matter as the display text tells us where to go.
