Anyway to NOT have the client round it?

Actually, MONEY is fixed point, with 4 decimal places. The client almost

always rounds this to two decimal places, though.

I'm not sure I'd call it a "problem".  It could be a feature, letting
you not round things off to the nearest penny.  "Money" doesn't usually
imply fractions of a penny; if you need that, you need a floating point
or exact numeric type.

I used Microsoft's osql.exe and Query Analyzer.  It seems they do not
round MONEY types when converting them to strings.  Microsoft's isql.exe
rounds to 2 places.

I want to emphasize this is not standardized.  T-SQL itself rounds to
two positions:

1> select cast(cast(.116 as money) as varchar(30))
2> go

------------------------------
0.12

One way around it, as you observed, is to convert to NUMERIC first.

No, the driver certainly doesn't convert anything unless asked.  Likely
you're seeing PHP behavior, about which I don't know very much.
