Create trigger that executes on date

15-May-13 18:00

What is it with you people today, the previous bloke wanted to use a trigger, you want to deploy a dtx and schedule it with some tool. USE A SQL JOB. That is precisely what it is designed for! there are a whole bunch of stuff available [^]

Hi. I am creating an application that uses sqlserver and asp.net c#. I need to create a trigger that inserts data into a table 30 days before an expiry date field in another table. I have created the trigger but dont know how to implement the dates? Any suggestions would be appreciated.

Does the date go in when the "expiry date" column is populate or do you want it to go in 30 days before the date?

What you are describing is not a trigger spit but a JOB, the job would call a proc that checks for expiry dates 30 days away and insert the appropriate record. You would schedule the JOB to run daily.

thanks for the reply. I had a feeling a trigger would be difficult or impossible to implement in this way.. Not sure how to create this job tho. Any pointers would be appreciated?

I already have a table with an appointment date entered. I need to update another table 30 days before before this appointment date. Thanks

Create a stored procedure that does the following
Get the expiring records
insert the relevant data into the target table.

In SSMS create a Job that calls the stored proc
schedule the job to run every day

Regarding DB2 Rows to Column String Concatenation

14-May-13 23:24

My usual attempt to resolve a sql error is to drop the error message into google[^] - seems like it is a common problem.

Hi All,

In DB2, i have used XMLAGG built in function in order to convert Rows to Column String Concatenation. Since lot of records are available in the table, performance wise it was too slow. Whether any user defined function is available for DB2 for string concatenation.

Thanks in Advance.

How to Update this request Balance Column

EmpID Leave_Year Taken Credit Balance
435 2014 0 22 22
435 2013 10 22 12
435 2012 24 22 0
435 2011 20 22 2
435 2010 23 22 0
435 2009 21 22 1

I want to Update this table Balance column value with the Next row Balance column value

eg: Leave_Year 2011, Balance value (2) Update with Leave_Year 2012 Balance Value (0)

0 - 2 = -2 should get in 2011 Balance column, use with this where condition, where Next row (2012) Taken>0

Hi,

Check the Script

SQL

SELECT M.ID,(ROW_NUMBER() OVER(PARTITION BY M.EmpID ORDER BY M.EmpID)) 'RowNumber', M.EmpID, M.Leave_Year, M.Taken, M.Credit, 
(SELECT SUM((ISNULL(Balance,0.0))
 FROM Table_Name WHERE ID<=M.ID AND EmpID=M.EmpID)
FROM Table_Name M
ORDER BY M.EmpID

I wouldn't do that. It's against the "Rules" of normalization. You don't want to make a row dependant on another row in the same table.
Think of all the fuzz to update the table when you find out someone inserted some wrong data last year, or when HR decides to change the rules (quite probable actually).

So you should make a query that gets you the result you want instead.
Hint, checkout ROLLUP.
For example:

SQL

SELECT EmpID,
       CASE WHEN (GROUPING(Leave_Year) = 1) THEN 'Total Balance'
            ELSE ISNULL(Leave_Year, 'UNKNOWN')
       END AS Leave_Year,
       SUM(Balance) AS Balance
FROM   MyTable
GROUP BY EmpID, Leave_Year WITH ROLLUP

I haven't tested this code, but it should give you an idea.
I also assumed SQLServer, Different Databases have different syntax. Use Google.

Migration process.

Several screens (or one very functional one) to view the data in a variety of ways like by Phase, by ESXHost, by Application.
I think if we have several drop downs for filtering then that would work; so I can choose Phase 1, to show only the databases that will be migrated in Phase 1, then I can choose some other criteria and the screen shows a subset of data etc.
3. The Pre-requisites and Post-Migration checks should show whether the Phase or database migration is ready to start or is ok to complete.

Need your opinion on querying data for presentation on winforms / web page and for reports

Dear all,

I require your opinion on what approach is good and/or practical for the following scenario.

There is a web application which queries data from SQL server.
For example:

Users report to a manager
1. The process by clicking a button is finding who reports to me (manager)
2. So there is a stored procedure written to find the users reporting to the manager

Now, there is a report (rdlc on the web server displayed via reportviewer control) which takes the manager as an input to generate report data for the staff members reporting to that manager.
The stored procedure for this report uses existing stored procedure (as in step 2 above) to find the staff members reporting to the manager and then generate required data.

My question is:
1. Is this the right way of doing this
2. Is there a need to develop a separate SQL view just for this report
3. What would be the best approach on doing this.

Please help.

Thanks

Regards,
Nayan
