I've got to ask because I am always looking for the simple solution to things....

If trailing "0"s are allowed, why bother with all that?

Why not just (based on the column definition of decimal(9,4))

select ColumnA, 10000 as Modifier, CONVERT(BIGINT, ColumnA * 10000) as Result

from @t

It's not beautiful or clever but it works and is a tiny weeny bit more efficient and easy to understand.

Excellent suggestion but I'll go one better than that... why in the hell do they need values without the decimal point to begin with? 😛

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

@jeff 😀

(I have seen that format quite often in data interface files - as it avoids the issue of different locales/regions using different decimal seperators e.g. "." and ",")

Ah... got it. Thanks. It does seem strange to waste an INT or even a SMALLINT to hold numbers like 10000 when a TINYINT to hold the "4" as an exponent of 10 would do.
