In SQL Server Management Studio, place this query in the workspace and click on the icon that has a description of "display estimated execution plan". This will give you an idea of where there may be table scans and where you might be able to add an index to improve your performance.
You should also check to see if your statistics are updated on the tables and indexes involved in this query before running the "display estimated execution plan" as described above.

Hi there I am trying to update a field in our contact table. I have a view which contains all of the contacts that i need to run the update for, my question is:
How do i update a contact table but only update the contacts that are in my custom view?
|
|
|
|
|
This example is based on the AdventureWorks database;
UPDATE HumanResources.Employee
SET Title = 'updateFromView'
WHERE EmployeeID IN (SELECT EmployeeID FROM HumanResources.vEmployee)
The select statement gets a list of ID's in the view. You can then update all the records in the table that have this particular ID. You'll need something to identify each record individually for this to work. If there isn't, then try to add the primary key to the view. If there is no primary key defined in the base-table, add an identity to fullfill this role.
Good luck

Hi,
I have a table which looks like the following.
OriginalTable
OriginalTable_Id(pk) OriginalTable_Name(unique)
---------------------------------------------------
1 NewColumnName1
2 NewColumnName2
...
I need to make it look like this table below dynamically:
NewTable
NewTable_Id(pk) NewColumnName1 NewColumnName2 ...
---------------------------------------------------------------
I know I need to create a new tempory Table (using tempDB?), but I don't know how to get the values in the table to be the new column names.
I have this at the moment:
CREATE TABLE NewTable
(
NewTable_Id INT PRIMARY KEY,
???
)
???:
Would it be something like:
SELECT OriginalTable_Name FROM OriginalTable
Any tutorials or advice would be greatly appreciated.
Thanks in advance.
hmmm pie

Brilliant, that's exactly what I was looking for thanks alot.
But how can I get the name of the columns dynamically.
eg.
The value is '198' so how can I make it the column name without knowing the value?
Edit:
Thanks again for your help.
Two minutes after posting this reply and Googleing 'Dynamic Pivots' I found this[^] which solved my problem.
Sorry for the inconvenience.

Hi
I have a stored procedure that takes an XML as a parameter. The problem is that anyone could call it passing in any XML. How do i write the stored procedure so that the XML that it takes in as a parameter is based on a specific schema?
Thanks

Hi
I Made Setup from my C# program (that work's with Oracle 10g)
when I try to run this program - in different Computer, i got this error message:
unable to load dll 'OraOps10.dll'
what it can be ?
thank's in advance
|
|
|
|

Did you add the reference to OraOps10.dll to your project? Did you copied this library also to the output folder (where your app is located)?
|
|
|
|
|
|
Maybe you have to install some kind of oracle client at the target computer.

I think so, but which file's I need ?

Hello. I want to save the RowCount returned value in a variable and want to print (+1 with 'A' prefix).
I created a variable as int.
declare @TotalIntRow as int
Now I'm unable to assign the returned value of rowcount in a variable.
i use these ..
@TotalIntRow = select Count(*) from Rcount
Error :- Msg 137, Level 15, State 2, Line 1
Must declare the scalar variable "@TotalIntRow".
set @TotalIntRow = select Count(*) from Rcount
Error : - Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'select'.
[I also tried to add a demo value , Set @TotalIntRow = 1; , but showing message number 137 as above mentioned]
How could I save the value in it.
|
|
|
|
|
Try this one;
DECLARE @TotalIntRow AS INT
SET @TotalIntRow = (SELECT COUNT(*)
FROM Rcount)
PRINT @TotalIntRow
Don't forget that the DECLARE statement should be used to declare the variable, before using it.
Hope this helps

Awesome mate.
But I cant understand one thing, if I do these steps individually I got scalar error something. why so ? just curious about it. Ain't the values are stored permanently in it?
BTW.. If even I run the above scripts do the variable takes additional space or they get removed after application shutdown?
Begin
DECLARE @TotalIntRow AS INT
SET @TotalIntRow = (SELECT COUNT(*)
FROM Rcount)
print @TotalIntRow + 1
Insert into Rcount Values(@TotalIntRow)
End
I m getting my partial desired result. I want to add prefix 'A' with the result set .. When I did .. I got , can't convert (variable declared for storing A) to int data type..
|
|
|
|
|
Oh my god, I can't believe I did it..
Begin
DECLARE @TotalIntRow AS INT
SET @TotalIntRow = (SELECT COUNT(*)
FROM Rcount)
print @TotalIntRow + 1
Insert into Rcount Values('A'+ Convert(varchar, @TotalIntRow))
End

Well done dude

Not permanent, they are 'lost' once the command is finished executing. (In this case, once it passes the END statement) That's also the reason why they can't be executed separate, they are interpreted as separate commands if you execute them line by line separately.
nt_virus wrote: BTW.. If even I run the above scripts do the variable takes additional space or they get removed after application shutdown?
They are gone as soon as the script (the complete collection of lines) are finished, unless you store them in a table somewhere. Most applications execute their script and close the connection to the database when done.
Good work

I am using a piece of automation software called Taskcentre, this has it's own database. This morning we were having issues with the software and it turns out that an essntial table has been cleared of all data.
There are currently no backups for the database and all tasks that have been created over the past year are now gone unless i can find a way of restoring the database to 2 - 7 days ago.
I was wondering if anyone had any ideas.
