Incorrect. Take the time to RTFM. You'll be pleasently surprised at how powerful and full featured the **FREE** advanced feature SQL Server 2005 Express edition is.

Aaargghhh, I'm getting confused...
Here is my SQL statement:
SELECT DISTINCT(pb.id), name, file, alttext, votecount, showcount, rating, link, lastwin_year, lastwin_month, MAX(place) AS place FROM pb LEFT JOIN pv ON pb.id = pv.id WHERE pv.lastwin_month = $current_month AND pv.lastwin_year = $current_year GROUP BY pb.id, pv.lastwin_year, pv.lastwin_month ORDER BY rating DESC LIMIT 0, 3
The problem is that it returns 0 rows if the table pv is empty. How do I make it return 3 pb rows with highest ratings if pv is empty?
If there are 3+ rows in pv, the SQL statement works perfectly. The only fields that are unique in the two tables are pb.id and pv.id. pv.lastwin_year, pv.lastwin_month are not unique.
Thank you,

A good idea, but it doesn't solve the problem 
I still get 0 rows back.

pv.lastwin_month = $current_month AND pv.lastwin_year = $current_year
You must allow these two columns to be null as well example
(pv.lastwin_month = $current_month or pv.lastwin_month is null) and
(pv.lastwin_year = $current_year or pv.lastwin_year is null)

... that will retrieve some rows, but what about the rows where lastwin_month != $current_month and lastwin_month IS NOT NULL (and same for lastwin_year)? These rows are not retrieved 
|
|
|
|
|
If you care about rows that != a value, why are you specifing them in the where clause?

What I want are the 3 rows in the pb table with the highest rating.
If these rows have a match (id) in the pv table, I want a row of pv information for each pb row as well. The information in pv is only relevant if lastwin_year and lastwin_month match the $current_year and $current_month parameters. No information should be retrieved from pv if no matching lastwin_year/lastwin_month can be found. Place should be as low as possible.
For example:
pb
---
id = 1, rating 56
id = 2, rating 63
id = 3, rating 42
id = 4, rating 70
pv
---
id = 2, lastwin_year 2006, lastwin_month 10, place 3
id = 2, lastwin_year 2006, lastwin_month 10, place 1
id = 3, lastwin_year 2006, lastwin_month 7, place 3
id = 4, lastwin_year 2005, lastwin_month 8, place 3
id = 4, lastwin_year 2005, lastwin_month 9, place 3
desired result ($current_year = 2006, $current_month = 10)
---
id = 4, rating 70, NULL
id = 2, rating 63, lastwin_year 2006, lastwin_month 10, place 1
id = 1, rating 56, NULL

I think this is what you are trying to do
select top 3 *
from pb left outer join
(select * from pv where lastwin_year = year and lastwin_month = month) b on pb.id = b.id
order by value

Hi,
I currently have a stored procedure which is able to delete a record of my choice..
Instead of having the RECORD deleted, I would like the RECORD to disappear from the Datagrid, and have a boolean value of the 'Deleted' Field in that RECORD be set to 1...
Is this implemented in the Stored Procedure? Any ideas would be appreciated..
|
|
|
|

This is a very common approach. There should be no problems implementing this into a stored procedure (except you will have to remove the item from the datagrid in the code).

Thanks for the reply. Appreciate it. I'll go figure it out.
Take care.

I would Imagine that you are populating your Datagrid in a method. If you do not have a separate method for this I would highly recommend it. When the user activates the UI control to delete the record from the datagrid I would also call the method that populates your datagrid. If you call this method after you delete the DB record your Datagrid will automatically re-populate with out the record.
Hope this helps.

I have the below query but would like to use a wild card value to do the search.
I need to pass a value like "on" and find, Jason or Preston. It would be nick if it is also not case sensitive....
This value is coming from VB.Net App and this is messing with me...
My Access (SQL) statement is:
SELECT *
FROM MainTB
WHERE myCustomer Like [@myVar];
But the LIKE needs to be [%myVar%] I think.
Feedback welcome please......

|
|
SELECT *<br />
FROM MainTB<br />
WHERE myCustomer Like ('%myVar%');
|
|
|
|
|
Running this query from access it does not ask me for an input it is looking for a user of %myVar%
As it is in the ' ' string quotes... I have already found this and tryed it...
Any other thoughts.....
?

The string concatenation character might help
select *
from MainTB
where upper(myCustomer) like '%'|upper(@myVar)|'%' This will also make it case insensitive.

The following error is occuring while attempting to connect to sql server the connection string is as follows:
"conn = new SqlConnection("Password=786;data source=DBSERVER;initial catalog=Venture;persist security info=False;user id=sa;workstation id=Venture;packet size=4096");"
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)

I've seen this error occur when SQL Server is not running. Not sure that is your problem, but it is something to eliminate.

It could be exactly what it says. There is a configuration tool for SQL 2005 that will let you check this. Check the server protocols. There will be a short list something like this:
Shared Memory Enabled
Named Pipes Disabled
TCPIP Enabled
VIA Disabled
If you right-click on TCPIP and select properties you might be as surprised as me to find this:
IP1
Active Yes
Enabled No
Address 192.168.1.1
...
IP2
Active Yes
Enabled No
Address 127.0.0.1
...
Apparently SQL server comes with most things turned off. Try setting the Enabled(s) to yes and see if your problem changes. I was not using the TCPIP, so could not test it. Please post back if this made a difference.

Thanx!!
It is now working fine.
I just enabled the named pipe, after that it is working.

Hey all,
Is there a way to know when table changed and who changed it?
is there a default table that logs those kinds of changes in MSSQL 2000?
Thanks
RoyRose.

Nope, unless you've enabled it. Article here talks about it.[^]
If it's just one table, then you can implement it yourself using triggers etc...
Googling for "sql server audit trigger" provides a load of methods.
