If you are using the cursor variable form, there are five possible return values:
❑ 1 — The cursor is open. If the cursor is dynamic, its result set has zero or more rows. If the cursor
is not dynamic, it has one or more rows.
❑ 0 — The result set is empty.
❑ -1 — The cursor is closed.
❑ -2 — There is no cursor assigned to the cursor variable.
❑ -3 — The variable with name cursor variable does not exist, or if it does exist, has not had a
cursor allocated to it yet.
Date and T ime Functions
This is an area with several new items in SQL Server 2008. In addition to working with timestamp data
(which is actually more oriented toward versioning than anything to do with a clock or calendar), date
and time functions perform operations on values that have any of the various date and time data types
supported by SQL Server.
When working with many of these functions, SQL Server recognizes eleven “dateparts” and their abbreviations,
as shown in the following table:
Datepart Abbreviations
year yy, yyyy
quarter qq, q
month mm, m
dayofyear dy, y
day dd, d
week wk, ww
weekday dw
hour hh
minute mi, n
second ss, s
millisecond ms
