Hi, how can I format number field in TSQL ? For example, in database I have field decimal(9,3) with value 123456.789 and I want get
123 456.79
or
123,456.8
I want define thousand delimiter and number decimal places.
In datetime fields is good function convert, but for decimal or integer not.

Thanks , Petr

sorry, i forgot the second convert:

select convert(varchar(30),convert(money, 32234344.9278),1)
-----------------
32,234,344.93

The convert to varchar needs to be from money to use the style property. See the convert topic in the BOL

unfortunately, this is not possible.
Of course, you could REPLACE the "," by " ", and eventually truncate the decimal places using

v is the formatted column like above,d the number of decimale:
for d=0:  LEFT( v , CHARINDEX ( '.', v ))
for d=1:  LEFT( v , CHARINDEX ( '.', v )+2)
for d=2:  LEFT( v , CHARINDEX ( '.', v )+3)
d>2 not possible :-)

Now, if you really want better control of formatting, I would rather use the front-end language which typically have much better options to do so. Just an idea.

If you are in SQL 2000, you could write a function which would give you any specific format you wanted.
