Hi all,
I need to relocate the datbase to another drive on my server and i need to make sure that all permissions and rules, diagrams are moved also to the new location. I can relocate either by copying and pasting mdf and ldf to new location and then attach or by backup and restore. I need to keep the same database name.
Do these above 2 ways guarantee me relocating with keeping all my permissions?
thanks

Yes, either detach and reattach in the new location, or backup and restore in the new location. If it is staying on the same server all these will be preserved.
If you move to a different server you will have to connect the logins (which are server wide in scope) with the users (which are database scope) but that's it.
I tend to go with the backup and restore model myself because the original is untouched until I'm satisfied everything is okay and I can take down the original. But if you are keeping the same database name you obviously can't keep the original running concurrently.

currently i m using ms-sql server 2000
CREATE TRIGGER [dateupdate] ON [ORMDatapro].[tab1]
FOR INSERT, UPDATE
AS
Update tab1
SET Initiated = Case WHEN Datestarted IS NULL OR LEN(Status)=0
OR (Status IN ('Cancelled', 'Cancelled merged', 'Cancelled split'))
THEN 'NA'
WHEN Status IN ('Complete', 'Close')
THEN DateDiff(dd, Signoff ,Datestarted) + 1
WHEN Status IN ('In Progress')
THEN DateDiff(dd, GetDate() ,Datestarted) + 1
END
Where Exists (Select * from INSERTED)
Here,
Datestarted, Signoff - datetime (datatype)
Status, Initiated - nvarchar (datatype)
When i save the above trigger and change any value in "tab1" table, the error Syntax error converting the varchar value 'NA' to a column of type int.
help me

The error message kind of says it all. Its obvious from the sql what is causing it, so why not just fix it?

It means that Initiated (the column) is an int (a number) and 'NA' is a varchar (not a number). It expects you to put a number in a column that is marked as a number. It does not expect you to put in varchars.

Hi,
I have two select statements that retrieve a couple of rows as follows:
Col 1

However I want to combine these two columns in one select statement to produce:
Col 1 Col 2

B 2
C 3
D 4
Please help

I recently did an article that included a pivot, maybe it can help you. If you are struggling with the existing examples I can only recommend you keep looking, sooner or later you will find one that makes sense.

Thanks Holmes,
I've found something but it doesn't work well, maybe you can advise me as I'm not professional when it comes to SQL..
CREATE TABLE TEST(F1 NUMBER(1),F2 NUMBER(1),F3 NUMBER(1))
/
INSERT INTO TEST VALUES(1,2,3)
/
SELECT X.C1 AS "COLUMN NAME", Y.C2 AS "VALUE"
FROM
(SELECT column_name AS C1 from user_tab_columns where table_name = 'TEST') X,
(
SELECT F1 AS C2 FROM TEST
UNION
SELECT F2 FROM TEST
UNION
SELECT F3 FROM TEST
) Y
/
The bloody output is:
COLUMN NAME VALUE
------------------------------ ----------
F1 1
F1 2
F1 3
F2 1
F2 2
F2 3
F3 1
F3 2
F3 3
9 rows selected.
Why is it matching every left value with all the values?? Please help Holmes

This worked for me but the column names are not dynamic. You could put then into another table and do a join
<br />
--And you can keep out of my database please<br />
DECLARE @Tbl Table(F1 int,F2 int,F3 int)<br />
<br />
INSERT INTO @Tbl VALUES(1,2,3)<br />
<br />
SELECT *<br />
FROM @Tbl<br />
<br />
<br />
SELECT 'F1' Col, F1 [Value]<br />
FROM @Tbl T <br />
UNION <br />
<br />
SELECT 'F2' Col, F2 [Value]<br />
FROM @Tbl T <br />
UNION <br />
<br />
SELECT 'F3' Col, F3 [Value]<br />
FROM @Tbl T <br />

Hi
I've an UPDATE statement inside a stored procedure, when I execute the SqlCommand.ExecuteNonQuery() function I get a return value of -1, but I need to get the # of rows affected by the update statement.
Any Idea how to do this?
Thanks

Add an OUT parameter to your stored procedure and using it, return the number of affected rows. To resolve it inside the procedure use @@ROWCOUNT.

Thanks alot, it worked!

declare a variable and, after the update,
set @Var = @@Rowcount<br />
Select @Var Records

Or something that can allow us to select column names from a one-row table where a specific column value exists
I mean, I want to get the column names of a table that has for example the value '1' in the first and only row of that table
Example:
A B C
-- -- --
0 0 1
The output should be:
C
Please tell me if you can make this happen from Sql.
Many thanks guys!

It could be done but not in 1 select statement.
A combination of a while loop to get the column names from the system info views and a select on the table to test the value of the column could acheive it.
What happens when 2 or more column have a value?
I suspect this is a really badly designed table. I recommend that you look into the data structure if it is possible.

Hey Holms,
Mycroft Holmes wrote: I suspect this is a really badly designed table
No, it's "terribly designed" and no, there's no way I can modify the structure
Mycroft Holmes wrote: What happens when 2 or more column have a value?
It will return those Column names just like rows.. like
A
B
C
Thanks for your help though!

You might look into unpivot, I've never used it though.
Sounds like an 80s legacy system to me

Yah, tell my Holmes, do you know how to transpose columns with rows in a select statement, that should be pretty doable and I see it everywhere when googling but cant apply it

What possible business reason could you possibly have that the servers DSN changes. I can understand an occassional change, say once a decade but "constantly" seems a little weird to me.
As you connectin relys on stable properties I see no way this could be acheived. It would require foreknowledge of the servers name/address
