Hi Friends,
I am using SQL Server 2005. I am facing the following problem. I need to know how to apply if condition in query.
I am having one table called Test1 with two fields c_name, average.
CC 7
CC 6
CC 8
IGC 2
IGC 4
IGC 6
HC 4
HC 5
NM 9
NM 6
NC 2
NC 5
NC 9
JC 4
JC 3
JC 1
The above are the values in that table.
Now I am using the following query to display the c_name, count(college) with average >5 group by c_name
select c_name,count(c_name) as Total from test1
where average>5 group by c_name
Result :
CC 3
IGC 1
NC 1
NM 2
Based on my query I am getting the above result. In the above result the colleges HC and JC are not coming because it has average only less than 5. But for my case, I want to display the college name with the total as 0 if that college doesnt have average >5. I need to modify the above query to get the result like below.
CC 3
IGC 1
NC 1
NM 2
HC 0
JC 0
Please help for this.
Thanks in Advance,
Regards,

Try this:
select c_name, sum(case when average > 5 then 1 else 0 end) as Total
from Test1
group by c_name

Backups created with Microsoft SQL Server 2005 cannot be restored to an earlier version of SQL Server.
With the help of Export/Import OR some third party Tool you can transfer your data from 2005 to 2000 and this is the way only.

Seems reasonable to me, what makes you beleive you will be able to restore a 05 DB on 2000. I would have thought this would be a futile effort.
You will be able to DTS, or select the data across. You may even be able to use replication but restore, not a chance.

Every morning I have a temporary table that gets updated with Customer Sales data (year to date, month to day, last year to date, etc), from another database. One problem I have is that I get every single customer from that database, even if a customer's MTD, YTD,LYTD figures have no changed, resulting in getting 625,000 records. Another is that I need update Existing customer with the data in my temp table. I tried using a while loop and looping through my table to update records. I also tried select the records from the temp table and comparing the values to what is in the existing, the placing those records in a table variable and using a cursor on the temp table. Both of these take entirely too much time. Here is the T-sql for reference...
Declare @ARbal money,
@CustTreeNodeID uniqueidentifier,
@CustomerNumber varchar(50),
@CustomerUpdateID int,
@LYSales money,
@LYTDSales money,
@YTDgm money,
@YTDSales money,
@MTDSales money,
@LMTDSales money
Declare @t table
(
CustomerUpdateID int,
CustomerNumber varchar(50),
YTDSales money,
LYSales money,
ARBal money,
LYTDSales money,
MTDSales money,
LMTDSales money
)
insert into @t(CustomerUpdateID, CustomerNumber,YTDSales, LYSales,ARBal, LYTDsales,MTDSales,LMTDSales)
select CustomerUpdateID,
CustomerNumber,
YTDSales,
LYSales,
ARBal,
LYTDSales,
MTDSales,
LMTDSales
from _CustomerUpdate u
where exists (select 1 from CustTreeNode c join CustTreeNodeaccountAssoc ca on ca.CustTreeNodeID = c.CustTreeNodeID and (u.LYTDSales != ca.LYTD or u.YTDSales != ca.YTD or u.MTDSales!= ca.MTD or u.LMTDSales !=ca.LMTD ))
declare mycursor cursor forward_only
for select CustomerUpdateID from @t
open mycursor
while (1=1)
begin
fetch next from mycursor into @CustomerUpdateID
if @@Fetch_status <>0
break;
set @CustomerNumber = (Select CustomerNumber from _CustomerUpdate where CustomerUpdateID = @CustomerUpdateID)
if isnull(@CustomerNumber,'')<>''
begin
set @CustTreeNodeID =(select CustTreeNodeID from CustTreeNode where CustomerNumber = @CustomerNumber)
end
select top 1 @YTDSales = YTDSales,
@LYSales = LYSales,
@ARbal = ARbal,
@LYTDSales = LYTDSAles,
@MTDSales = MTDSales,
@LMTDSales = LMTDSales
from @t where CustomerUpdateID = @CustomerUpdateID
update CustTreeNodeAccountAssoc set YTD = @YTDSales, LYTD= @LYTDSales,Balance = @ARbal where CustTreeNodeID = @CustTreeNodeID
end
close mycursor
deallocate mycursor
|
|
|
|
|
Can you re-write the cursor to not use cursors? I think cursors are slow in SQL.
|
|
|
|

Like I said I tried using a loop using a status field on the temp table: something like this
while(select top 1 from _customerUpdate where [Status] ='INC') = 'INC'
begin
Begin Try
perform customer update logic here...
End try
Begin Catch
End Catch
Update _CustomerUpdate set Status ='CMP' where CustomerUpdateID = @CustomerUpdateID.
End
Either way both of these ran incredibily slow...

Am developing a multi user VB.NET app and i would welcome suggestions on how to code my connection code.
How do i put it such that i only write it once(maybe a module -like i used to do in VB 6) or put it in an XML config file
|
|
|
|
|
Use the config file. If its .NET2 or higher there is a app setting of connectionstring specifically for this.

Hello,
I have a product table.
I have a ProdIn table with fields (ProdIn,ProdOut,Cost)
ProdIn,ProdOut are the fields from Product Table.
Now I want to fill up ProdIn table with all the combinations of Products.i.e If I have 2 products ,I have 2^2 records in ProdIn.
I don't know how to do this.
I have done this which is wrong
Select Product as ProdIn ,Product as ProdOut from Product
Prithaa

|
|
This will probably do it -
select a.product as prodin,b.product as prodout
from product a, product b

Just create an on insert trigger, use the special inserted table to get the data you are inserting and update the real table as required.

Hi Bob,
Do you have any other Method?
|
|
|
|
|
Not really. From your original post I would use a trigger, or if it was a one off load maybe run some SQL to do the update after the load, but it all depends on what you are trying to do.
