"FOR" was used before SQL allowed BEFORE or INSTEAD triggers; there were only AFTER triggers, and the syntax used the word "FOR" instead of "AFTER".

After other trigger types were added,...

The advantage to tempdb is that there is less overhead writing data there since SQL "knows" it never has to recover tempdb.

That seems like a reasonable approach. Using REPLICATE() will make it easier to see how many numbers are in the pattern and/or adjust it later:

WHERE PATINDEX('%[0-9]' + REPLICATE('[0-9 -]',...

Note that you can use a "real" table name in tempdb; that is, a table name that does not begin with # or ##. The table will then remain...

Until you get to SQL 2012, you also have the "quick-and-dirty" version of that, using COMPUTE:

SELECT Curr_date, Action, AVG(Duration)/1000 as Avg_Duration

FROM Table_1

WHERE Curr_date = CAST(GETDATE() as DATE)

GROUP BY Curr_date,...

There must be more fragmentation in a history table than a current-data-only table.

For single row lookups, this is not really a performance hit.

But for table scans, even...

Also, be sure to check: sys.sql_expression_dependencies.

And not just in its own db but in other dbs, esp. on the same instance.

And the usual disclaimer: even that isn't guaranteed to be...

My best guess on the very limited info so far is something like this:

select MonthName, DocName, count(distinct day(appointment_date)) as days_worked

from Appointments

group by MonthName, DocName

You could easily use master for that. Especially given that you must use master for some procedures anyway. Moreover, it's much easier from SQL2005 on to distinguish your...

sp_MSforeachdb is indeed a cursor, and not a particularly good one.

Still, it exists, and it's useful for quick-and-dirty tasks sometimes, particularly if you don't have a lot of dbs.

So, I'll...
