I just ran the following update on my local database. It has one user, me, and the update query took 57 seconds to update 111k records. That seems pretty long too me, so I assume the cost of the update is in the newid() function call. Pretty expensive.
|
|
|
|
|
Can you provide the update statement.
|
|
|
|
|
You might want to provide the actual update statement. It might be something else that you are doing that is expensive. I've updated hugh quantities of rows with a NEWID() before and it wasn't this long.
|
|
|
|
|
Expensive queries tend to be the result of not using key fields in the filter criteria. Have you viewed your execution plan to see what it is doing? If you are doing a sequential scan, this will be the cause of your problem.
I really don't see the problem being with the newid() function.

It was a table scan, but redoing the column addition and running the update again gave a time of 2s. The first one is probably due to some housekeeping work my very underused server was doing. The query is:
alter table myDoc<br />
add<br />
GlobalDocID uniqueidentifier default newid()<br />
go<br />
update myDoc<br />
set GlobalDocID = newid() where GlobalDocID is null

while fetching from SQL Server it is possible, to filter for a specific month & year.
for example
if the modify_dt is the column with datetime datatype
where clause for fetching this can be
1. WHERE modify_dt BETWEEN <frmdt> AND <enddt>
2. WHERE month(modify_dt) = <mth> AND year(modify_dt) = <yr>
if is for previous month (current month is Feb then prev. is Jan)
WHERE month(modify_dt) = month(getdate) - 1
AND year(modify_dt) = year(getdate())
-- modified at 22:45 Tuesday 13th February, 2007

Thanks For U r Reply. but i am declaring that month fields as nvarchar, am also uploaod all the databases from excel to Sql.
Now is it Possible to get Last month Details?
That table contain 42 fields and also No of records in it is nearly 850. Please help me to avoid olderdata's getting repeated. only i want last month Modified Records. Please tell me any other way to solve this Issue. ..
Thank You

does the data belongs to same year ? if so ....
In SQL datepart(m, getdate()) returns current month number
where clause can be used
MonthField = datepart(m, getdate()) - 1

Hi Guru's
I know how to trim varchar parameters ltrim(rtrim(@parameter)) but is there more explicit way of doing this? e.g. vb.net string.trim()
Thanks

I would like to find out how to insert images into a SQL table? I have an ID (int), Description(text) and Image(image).
Please help, I want to use a stored procedure to insert the data.
Thanks!

You just use the Image type as a parameter in your stored procedure. Then you can insert the information to your hearts content.

Hello,
I am using the DTSWizard.exe to import data into a SQL Server database from text files.
I have performed this operation several times before without incident. The database is running and by all accounts seems to be functioning fine. However, for some unknown reason, now when I try to select the database as the destination for my imported data, I get the error message pasted at the bottom of the page. Does anyone have advice for how I should proceed?
Your help would be greatly appreciated.

I've not seen that before, but it sounds like permissions on the physical log and data files (or the folder they live in).
Check that the files can be accessed by the account that is used by SQL Server service to log on (see appropriate SQL Server service properties in "SQL Server Configuration Manager -> SQL Server Services".
Hope that helps.

Hello everyone,
In our project, we created a SSIS package to load data from Excel into SQL2005 database.
Right now, I want to write code (whatever is vb.net, Vbscrip, or storedprocedure code) to change the existed excel worksheet name. If anyone can give me any suggestion with it, I will really appreciate it.

Scenario: A company has an internal Access database located on a server within their network. They would like to have a small read/write asp.net page within their website located a Hosting Server outside their network.
Question: Is it possible to setup a connection string from an external web application to an internal Access Database?
Any help would be greatly appreciated.

hi.
I want to select,for example, records from no 10 to 20.
I have no id column or ordered column .
i want this for paging in asp.net grid fro a table with one million records.
I wan retrive records 10 by 10
|

A common way to do this is to do nested selects. If you want records from number 10, and you want 10 of them, you select the top 20 records, then you do a select on the result set of that query, which asks for the top 10, ordered in descending order. Finally, you want to select this in ascending order, if that's the order you want.

I’m writing the following stored procedure:
USE Employees;
GO
IF OBJECT_ID('mrmsp_RetrieveEmployeeForEditting','P') IS NOT NULL
DROP PROCEDURE mrmsp_RetrieveEmployeeForEditting;
GO
CREATE PROCEDURE mrmsp_RetrieveEmployeeForEditting
@varEmployeeID INT,
@varTitleID INT OUTPUT,
@varDeptID INT OUTPUT,
@varLName VARCHAR(25) OUTPUT,
@varFName VARCHAR(15) OUTPUT,
@varMI VARCHAR(1) OUTPUT,
@varAddrTypeID INT OUTPUT,
@varAddress1 VARCHAR(40) OUTPUT,
@varAddress2 VARCHAR(40) OUTPUT,
@varCity VARCHAR(40) OUTPUT,
@varStateID INT OUTPUT,
@varZip VARCHAR(10) OUTPUT
AS
SELECT tblEmployees.[EmployeeID], tblEmployees.[TitleID],
tblEmployees.[DeptID], tblEmployees.[LName],
tblEmployees.[FName], tblEmployees.[MI],
tblAddresses.[AddressTypeID], tblAddresses.[Address1],
tblAddresses.[Address2], tblAddresses.[City],
tblAddresses.[StateID], tblAddresses.[ZipCode]
FROM Employees.dbo.tblEmployees
INNER JOIN Employees.dbo.tblAddresses
ON Employees.dbo.tblEmployees.EmployeeID =
Employees.dbo.tblAddresses.EmployeeID
WHERE Employees.dbo.tblEmployees.EmployeeID = @varEmployeeID
AND Employees.dbo.tblEmployees.Deleted = 0
ORDER BY Employees.dbo.tblEmployees.EmployeeID
SET @varTitleID = tblEmployees.[TitleID]
SET @varDeptID = tblEmployees.[DeptID]
SET @varLName = tblEmployees.[LName]
SET @varFName = tblEmployees.[FName]
SET @varMI = tblEmployees.[MI]
SET @varAddrTypeID = tblAddresses.[AddressTypeID]
SET @varAddress1 = tblAddresses.[Address1]
SET @varAddress2 = tblAddresses.[Address2]
SET @varCity = tblAddresses.[City]
SET @varStateID = tblAddresses.[StateID]
SET @varZip = tblAddresses.[ZipCode];
When I run the check routine it says there are no errors in the T-SQL statement, but when I try to run the SQL to place the stored procedure into the database I get the following errors:
Msg 4104, Level 16, State 1, Procedure mrmsp_RetrieveEmployeeForEditting, Line 28
The multi-part identifier "tblEmployees.TitleID" could not be bound.

Msg 4104, Level 16, State 1, Procedure mrmsp_RetrieveEmployeeForEditting, Line 35
The multi-part identifier "tblAddresses.Address2" could not be bound.
Msg 4104, Level 16, State 1, Procedure mrmsp_RetrieveEmployeeForEditting, Line 36
The multi-part identifier "tblAddresses.City" could not be bound.
Msg 4104, Level 16, State 1, Procedure mrmsp_RetrieveEmployeeForEditting, Line 37
The multi-part identifier "tblAddresses.StateID" could not be bound.
Msg 4104, Level 16, State 1, Procedure mrmsp_RetrieveEmployeeForEditting, Line 38
The multi-part identifier "tblAddresses.ZipCode" could not be bound.
I assume the SQL statement can’t bind the data from the indicated columns into the variables in the stored procedure.
What am I doing wrong?

dbo.tblEmployees.TitleID if you use multipart identifiers, you have to supply all three parts...
|
|
|
|
|
Actually, I think the syntax is wrong (you don't want the SET business at all)
Select @varTitlID = tblEmployees.[TitleID],@varDeptID = tblEmployees.[DeptID]...
FROM Employees.dbo.tblEmployees
INNER JOIN Employees.dbo.tblAddresses
ON Employees.dbo.tblEmployees.EmployeeID =
Employees.dbo.tblAddresses.EmployeeID
WHERE Employees.dbo.tblEmployees.EmployeeID = @varEmployeeID
AND Employees.dbo.tblEmployees.Deleted = 0
The 'order by' is not needed, since the query must have only one result row to work at all.
