Hi
Is there any reason I could not use VS2005 with SQL Server 2000. I have just started at a new organisation and they already have SQL Server 2000 (with no plans to upgrade). They don't, however, have any development tools, so I am looking at using VS2005.
Any input would be greatfully accepted.

I'm in need of some sql help
SELECT P1.name, P2.name , J.text FROM person p1, person p2, job J WHERE P1.persID = J.creatorID AND P2.persID = J.responsibleID AND J.id = 1
the above statement does not return any rows if the job J has null in the responsible field. But I want it to return an empty string for P2.name in that case. Is that possible. Would be thankful for any help!

You need an OUTER join. Start with this query.
SELECT p1.name as p1name, isNULL(p2.name, '') as p2name , J.text<br />
FROM person p1 INNER JOIN<br />
job J ON p1.persID = J.creatorID LEFT OUTER JOIN<br />
person p2 ON J.responsibleID = p2.persID<br />
WHERE (J.id = 1)

Post the complete query. You need to have a GROUP BY along with JOINs in your query b/c of an aggregate function.

the complete query is:
<br />
SELECT Description,COUNT(DISTINCT id_Stud)<br />
FROM Studenti, Istituti<br />
WHERE Studenti.id_Istituto = Istituti.id_Istituto<br />
GROUP BY Description;<br />
But the Distinct syntax is wrong i think...

Syntax looks fine, look for field name typos.

What do you mean?
I wrote it on Access too but it doesn't work..
I use an OdbcDataSet to retrive this information..maybe it's a DataSet's problem, i dont know!

Post your tables structure here.

ok, i have 5 tables:
Studenti(student):
fields -> CodiceStud(PK),NomeStud,CognStud,DataNascita,Classe,
CodiceIstituto(FK)
Istituti(school):
fields -> CodiceIstituto(PK),Denominazione,Indirizzo,Telefono
Professori(teachers):
fields -> CodiceProf(PK),CognProf,NomeProf,CodiceIstituto(FK),
CodiceManif(FK)
Manifestazioni(Competition):
fields -> CodiceManif(PK),Descrizione,Luogo,DataInizio
Iscrizioni(inscriptions):
fields -> CodiceStud(FK),CodiceManif(FK),DataInizio
The "inscriptions" table result from the N:N relation between student and competition.
The tables i need for the query are student and school only.
With this query i want to have as result the list of the school with the number of students who take part in one of the competition.
PS: Without the Distinct function, if a student take part in more then one competition he will be counted more time...

You could start with this rather not-so-elegant query and then fine tune it to your taste.
Select i.Denominazione, count(s.CodiceStud)
From Istituti i INNER JOIN Studenti s ON i.CodiceIstituto = s.CodiceIstituto
Where Exists
(
Select DISTINCT Iscrizioni.CodiceStud
From Iscrizioni
Where Iscrizioni.CodiceStud = s.CodiceStud
)

Aliases for table names.
You can define as alias like this:
SELECT * FROM MyTable t
INNER JOIN OtherTable o ON ....
where the alias comes immediately after the occurrance of the table name in the FROM or JOIN clause. I prefer to make this more explicit by writing it like this:
SELECT * FROM MyTable AS t
INNER JOIN OtherTable AS o ON ....

In my opinion, it makes it easier to read when using aliases

Im a beginner so im going to ask a stupid question that i did not find an anserw to in the documentation.
Is it possible to connect to sql 2005 over internet? So far i only done it with intranet.
If it is possible, could somebody tell me how it is done, or show me to an article concerning the subject?
(would also apreciate some security aspects that need to be considered)

I should be. I don't see why not, it is just TCP/IP traffic. A firewall might block it, of course.

Also, exposing your SQL Server over the internet is a security risk. Normally it should sit behind an propertly configured firewall so that it can only be used on an internal network. If you must expose it over the internet you should consider some sort of VPN (Virtual Private Network).

I need to include a column in an SQL Server table, which can hyperlink to some text stored somewhere inside or outside the same database.
Please help.

In case of the text store in the database you should scan through the table and search for the text that you need by using SELECT statement. Check here for the SELECT statment information.[^]
In case of the text outside the database you should know the file path. The field that you are create must store the file path and point to the specific file that you need to open it. Check here for the information about read and write to text file.[^]

Comparing only Time in Sql?
Hi Dears!
I have two Different DateTime Values i want to Compare only their times independent of Dates How to do it?
let
DateTime @dt1='2004-10-30 19:30:00.917'
DateTime @dt2='2005-11-29 15:00:00.917'
accordint to my requirements
@dt1>=@dt2 should be true as 19:30>=15:00
because i have to compare only the time not the Date how to achieve this in sql .Function required.

You can change your times to milliseconds since midnight and compare those.
CREATE FUNCTION MillisecondsSinceMidnight
(
@in DATETIME
)
RETURNS INTEGER
AS
BEGIN
DECLARE @retval INTEGER
SET @retval =
DATEPART(ms,@in) +
DATEPART(ss,@in) * 1000 +
DATEPART(mi,@in) * 60000 +
DATEPART(hh,@in) * 3600000
RETURN @retval
END

Hi, I have a problem while trying to install SQL server 2000 sp4. There are 3 component that i need to install:
- sql server sp4
- analysis serverice sp4
- msde sp4
The first 2 option could be install successfully. But when i try to install the last option (msde sp4) it display a message "The instance name is invalid" after i double click on the file setup.exe. Does any one challenge this problem before? If you have please let me know about the solution how to fix it.

You don't need to install 'MSDE SP4' on a regular instance of SQL Server: Developer Edition, Standard Edition, Workgroup Edition, Enterprise Edition or Personal Edition. 'MSDE SP4' is only for updating the SQL Server 2000 Desktop Engine, also known as MSDE 2000.
Stability. What an interesting concept. -- Chris Maunder
