Hi Zibi,
Assuming that "data" is declared as a [small]datetime column, then it
has no format in the database. The internal representation of datetime
is, in fact, a set of two integers (but the internal representation is
in fact not relevant).
For your query, the date/time constant is first converted to the
internal representation of either datetime or smalldatetime (to match
that of the "data" column), then the comparison is made. Obviously, the
first part (the conversion of '2005-05-24 14:07:28' to [small]datetime)
is the cause of your error. Obviously, some locale settings on your SQL
Server make it think that you use a yyyy-dd-mm hh:mm:ss format.
To prevent this kind of errors, use only the guaranteed safe formats for
date and date/time constants:
* yyyymmdd (date only - note: no dashes, slashes, dots or whatever)
* yyyy-mm-ddThh:mm:ss (date plus time - note: dashes between the
components of the date; colons between the components of the time and an
uppercase T to seperate date from time)
* yyyy-mm-ddThh:mm:ss.ttt (as above, but with milliseconds, seperated
from the time by a dot).
Best, Hugo
