Does SQL Server 2005 Express has the method that delete automatically rows ordered by time colum

Hi, I made table that stores monitoring data every 1 minute.

It should have only 60 minutes-data from current time.

I delete data which stored 60 minutes ago before insert.

I'll be happy to find that the database engine does automatically above procedure.

You could use an insert trigger which fires when new data is inserted. Place your delete statement here to delete old records.

does Level() do anything?

enclosed is the complete rdl for a report that has a table, contains groups
and calls the level function.
Returns the current level of depth in a recursive hierarchy. it looks like
the recursive part does not work?
what am I missing here?

</Report>Level function is for recursive hierarchies, which are tables that link back
to themselves. If you create a table such as...
CategoryID CategoryParent
1 0
2 1
3 1
4 0
5 4
6 4
7 4
8 2
9 2
10 2
11 9
12 10
13 12
and set your query to be
Select t1.CategoryID, t2.CategoryID as Subordinates from Sometable t1 left
outer join Sometable t2 on t1.Categoryid = t2.CategoryParent
Then you could use the level function to tell you how far each category node
is nested.

Does 2008 will offer a "between lookup"?

Hi,

does SSIS 2008 will finally offer a "between lookup"?

the current lookup support only the equal (=) operator, but when we play with Type 2 SCD dimensions, its important to also test the dates using a between.

or better, the operator used in the comparison should be an option instead of a equal only.

Thanks.

You can already do such lookup in SSIS 2005 using Partial or None cache Lookup mode.

Neither SSIS 2005, nor SSIS 2008 support such lookups in Full cache mode.

|||

but its a row by row process and everytime the system execute the query against the lookup database.

with million of rows and more to load , this is not efficient.

at least, do you plan to improve the lookup component?

Hi Willgart1,

There has been no announcement of changes to the lookup functionality in SSIS2008. Announcements on new functionality are not being made until Microsoft can be absolutely sure that that new functionality will make it - in other words they are announcing stuff after they've built it rather than before. Hence, because there has been no announcement doesn't mean there won't be anything. I'm keeping my fingers crossed on improvements to LOOKUP.

Alberto Ferrari wrote a Range Lookup component that we presented at an italian conference last month (www.sqlconference.it).

In the next days we should finish a little documentation of the component and we will publish it on www.sqlbi.eu

It works in memory and is pretty flexible in the way you can configure the match expression.

Just a few days... if you subscribe to the newsletter on www.sqlbi.eu you'll receive an update when it'll be available, otherwise you can check our blogs (http://www.sqljunkies.com/weblog/aferrari/ and http://sqlblog.com/blogs/marco_russo/).
