I think what he meant was "why don't you just go read the .sql file into the commandtext property of a sql command object and executenonquery". The only thing you need to be careful of is "go", but I also read in another post that colin wrote a utility to help with sql containing "go" in it.

If it's a local instance of MSDE, use the following command:
osql -E -i filename.sql The -E switch indicates to use Windows authentication, and the -i filename.sql indicates which file contains the statements to run. Run osql /? to see other options.

I use ADO.NET to execute sql. But it takes a lot of time, so after 30 seconds program show error message "Timeout expired!" (althrough I declare "Connect Timeout=600" in connect string). How to use SqlConnection without Timeout or with a long time?
Please help me!!!
Thanks!

There are two timeouts. The one you are using is for the connection. In other words, how long should the .NET application wait to connect (not do any work, just connect) to the database.
The other timeout it on the command object, CommandTimeout. This timeout is the amount of time that the .NET application will wait for it to perform what ever command you sent it.
Does this help?

Hi
I've got a login Proc that returns some data upon successful login.
I've just added some checking code before this data to verify that the user may log in etc, but the resultsets from these checks are being returned in the dataset. Is there some way to clear the results before doing my final select statement?
Thanks
Russell

Not too sure if this will help but when I have a structure like that I use a reader. I can then write the following:
if(r.Read()){
// they are valid, get user info
if(r.NextResultSet()){
while(r.Read()){
// return additional data for that person
}
}
}
r.close();

I'm trying to get SQL to not return the recordsets that the SP uses internally and just return the data i really want.
There's quite a bit of branching in the checking code which means i don't know exactly how many select statements will be executed prior to the select that i want executed.

The easiest way around this is to not execute queries that return rows.
Instead of:
SELECT *
FROM Users
WHERE ID = "Tom"
Do:
DELCARE @i INTEGER
SELECT @i = COUNT(*)
FROM Users
WHERE ID = "Tom"
You can use logic to determine if @i > 0 then process the rest of the login. You can use any number of variables in the SELECT. Just make sure your query only returns 1 row.
You can also use EXISTS:
IF EXISTS(SELECT * FROM Users WHERE ID = "Tom")
BEGIN
-- Do your work here
END

Hey all, I've got data structured like this:
ID - Contact - Company - Email
1 - Jeff - Acme - Jeff@Acme.com
2 - Hester - Acme - Hester@Acme.com
3 - Mort - Acme - Mort@Acme.com
4 - Jason - Widget - Jason@Widget.com
5 - Harriet - Widget - Harriet@Widget.com
I need to write a query that will return only the first contact for each company, in this case it should return:
----------------------------------------
1 - Jeff - Acme - Jeff@Acme.com
4 - Jason - Widget - Jason@Widget.com
Thanks in advance!

Not Tested but give it a try.

SELECT ID, Contact, Company, Email<br />
FROM [table]<br />
GROUP BY Company<br />
HAVING MAX(ID) = ID<br />

Just a little correction
SELECT ID, Contact, Company, Email
FROM [table]
GROUP BY Company
HAVING MIN(ID) = ID
|
|
|
|
|
Nope
something like
select * from [table] t where id=(select min(id) from [table] tt where t.company=tt.company)
HTH

|
|
|
|
Check this
SELECT *
FROM DeleteMe
GROUP BY Company
HAVING MIN(ID) = ID
|
|
|
|
|
It will nerver work. Read BOL about GROUP BY first before posting.
|
|
|
|
|
Why dont you try it first then reply. I have already tested it and it works fine.
I think you need some lesson on Group By.

|
|

well the query by alam_pune looks fine to me as well..... its a nice and simple sql and works fine too.....
|
|
|
|
|
select * from [table] where ID in
(select min(ID) from [table] group by company )

Hi !
My app is using SQLite as a database. I'd like to change the datatype of a column of several tables (for example changing from VARCHAR(10) to VARCHAR(50)) without loosing the existing datas.
How can I do this in SQL ? I didn't find anything ! Is it possible ?
Thanks for your help !

Just use the ALTER COLUMN syntax. If I had the following table:
CREATE TABLE DContact(
CONTACTID INT IDENTITY(1,1),
CONTACT VARCHAR(50),
COMPANY VARCHAR(50),
EMAIL VARCHAR(50)
)
I could change things like so:
ALTER TABLE DContact
ALTER COLUMN Email VARCHAR(100)
GO
This is TSQL that I wrote and tested, but it should be generic enough to work with your database.

Use "(local)" instead of "localhost". Off the top of my head I cannot remember the reason why, but there is a difference.
