I m facing a problem in this query

select a.eventid,b.name,convert(nvarchar,c.assigndate,106)as assigndate,<br />
convert(nvarchar,a.eventdate,106)as eventdate,a.event,a.details,a.eventtype from event as a left outer join emp <br />
as c on a.eventid=c.eventid left outer join user_info as b on b.userid=c.userid <br />
where(a.eventtype='Single Month' or(a.eventtype='All Month' and <br />
(select substring(convert(nvarchar,edate,102),9,4) from event where eventtype='All Month')>( select substring(convert(nvarchar,getdate(),102),9,4)) ))order by a.eventdateselect * from event<br />
<br />

In event table there are some fields like eventid,eventdate,eventtype n etc
In user_info there are userid, name n etc fields

i wanna get all record when
1> eventtype is Single Month and the eventdate is in current month n eventdate is heigher than currentdate
2> eventype is All Month and eventdate is heigher than current date

eventid -----eventdate ------- eventtype
1 -----2008-04-15 00:00:00 ----- All Month

2 -----2008-04-20 00:00:00 ----- Single Month

3 -----2008-04-16 00:00:00 ----- Single Month

4 -----2008-04-16 00:00:00 ----- All Month

The answer shd be eventid 2,3,4

Try this

select a.eventid,b.name,convert(nvarchar,c.assigndate,106)as assigndate,<br />
convert(nvarchar,a.eventdate,106)as eventdate,a.event,a.details,a.eventtype from event as a left outer join emp <br />
as c on a.eventid=c.eventid left outer join user_info as b on b.userid=c.userid <br />
WHERE a.eventdate > getdate()<br />
AND (<br />
(a.eventtype = 'Single Month' and left(convert(varchar,getdate(),102),7) = left(convert(varchar,edate,102),7))<br />
OR (a.eventtype = 'All Month')<br />
)

I believe Excel VBA does ADO, so you should be able to connect to the DB2 database and do your stuff. For connection information, look up www.connectionstrings.com[^].

I feel I have the wrong handle on your problem but...

If you want the additional of col1 + col2 then it is the same method as the multiply
If you are after the sum of all the records preceding the current record then you need to look into running totals (depends on your DB)

if you want the sum of the 2 cols included in the result set you need to do the query 2 times, 1 to get the total into a var and the seconed to include it in your result set

You really need to define your problem a little clearer. Remember we have not gone through the process of getting where you are stuck and do not have the code in front of us.

Depending on whether you are trying to just add the two columns together, or add the sum of the columns together, you could either do:

select tbl1.column1 + tbl2.column as summation

select sum(tbl.column1 + tbl2.column) as total

Is this what you are looking for:

select tbl1.column1,tbl2.column2,tbl1.column1*tbl2.column2 as Result, sum(tb1.column1*tbl2.column2) as Total

This query will have the Total column as the same value for all the rows.

sqldmo backup issue (Cannot open backup device)

If having it in the same row is Ok, then my earlier query should work for you (providing of course that you specify the correct join condition).

Hi...

I'm trying to get programmatically a backup file of my database, here is the code:

<br />
//Get a temporary file<br />
string BakFilePath = System.IO.Path.GetTempFileName();<br />
<br />
//create a backup class instance<br />
SQLDMO.Backup bak = new SQLDMO.BackupClass();<br />
//set the backup device = files property ( easy way )<br />
bak.Devices = bak.Files;<br />
//where to store<br />
bak.Files = "[" + BakFilePath + "]";<br />
//set the database to backup<br />
bak.Database = "MyDB";<br />
bak.BackupSetDescription = "Something";<br />
<br />
//perform the backup<br />
bak.SQLBackup(srv);<br />

Under VS2005 c# SQL Server 2005, in debug mode there are no problem.
When installing on a win xp with SQL Express 2005, I have the following error:

<br />
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot open backup device 'C:\Documents and Settings\JOZ\Local Settings\Temp\tmp19.tmp'. Operating system error 5(Access denied).<br />
[Microsoft][ODBC SQL Server Driver][SQL Server]BACKUP DATABASE is terminating abnormally.<br />

I like sqldmo backup because is really quick... but this issue is driving me crazy... Can somebody help me please? $Shucks | :-\$

Life is not short... the problem is only how you organize yourself

Maybe your SQL Server 2005 service is running under an account which has permissions to the backup folder, which the account used by SQL Express does not.
Try giving write permissions to the account under which SQL Express runs.
