Last Transact-SQL Statement Executed

Hello All,
Please how can I retrieve/save the last Transact-SQL
statements executed against a database? Can I use a
trigger for this?
Thanks.Triggers work on tables and will only fire for data
updates not selects.
If all your access is via SPs then you could log in the SP.
You could log in the client if you are in control of that.
Otherwise the easiest way is to use the profiler to log
statements to a table or text file.

Last & First SQL aggregate functions

I'm trying to migrate an app. from Access to SQL Server, and find that Transact-SQL does not support LAST/FIRST functions. Is there any alternative to these?

Below is the Access SQL statement:

SELECT Last(tblZoneNameString.Val) AS strZoneName, tblZoneNameString.TagIndex
FROM tblZoneNameString
GROUP BY tblZoneNameString.TagIndex
HAVING (((tblZoneNameString.TagIndex)>0));

Use MIN and MAX

In SQL Server 2005, you can do something like this: select tblZoneNameString.Val as strZoneName, tblZoneNameString.TagIndex from ( select tblZoneNameString.Val as strZoneName, tblZoneNameString.TagIndex, rank() over (partition by tblZoneNameString.TagIndex order by ?) as rk from tblZoneNameString ) as T where rk = 1 Where I've written ? you will need to put whatever column or columns answer the question "last in order of what?". Perhaps this is something like someDateTime DESC. Steve Kass Drew University JimNolandCBI@.discussions.microsoft.com wrote:
