As you are using dynamic SQL (and I don't see any reason why you need to do that), you need to put apostrophes around your variables. So, the where clause becomes WHERE UserID = ''' + @UserID and so on.

Also, the BEGIN doesn't need to be there - in fact, it causes an error.

Problematic connection string to SQL Express 2005

Hi all,
I have a problem that have haunted me for days and no suggestion I tried from CP worked... Please help!

I have installed SQL Express 2005 on Win2003 server and created a database. Authentication is in Mixed Mode. No firewall.
Here is what happened:

LOCALLY: (login as administrator)
1. I can open it using SQL Server Management Studio.
2. I SUCCESSFULLY connect to it programmatically (VC++) with any of the following connection strings:

Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Uid=myUsername; Pwd=myPassword;<br />
Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Trusted_Connection=yes;<br />

REMOTELY on XP SP2: (login as administrator and with SQL Server Native Client installed)
1. I can open it using SQL Server Management Studio (in both modes, SQL and Windows).
a. This confirms that I have correctly set up and enabled remote connection.
b. I enabled remote connection using both TCP/IP and named pipes.
c. I enabled Shared memory, Named pipes, and TCP/IP protocols.
d. I enabled and activated SQL Server Browser

2. I FAILED to connect programmatically. Here are some connection strings I've tried:
(most error messages: "Login failed for user 'admin'." (which is a renamed 'sa').

<br />
Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Uid=myUsername; Pwd=myPassword;<br />
Provider=SQLOLEDB;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Uid=myUsername; Pwd=myPassword;<br />
<br />
Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS,1433;Database=myDatabase;Uid=myUsername; Pwd=myPassword;<br />
Provider=SQLOLEDB;Server=myComputerName\MYSQLEXPRESS,1433;Database=myDatabase;Uid=myUsername; Pwd=myPassword;<br />
<br />
Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Trusted_Connection=yes;<br />
Provider=SQLOLEDB;Server=myComputerName\MYSQLEXPRESS;Database=myDatabase;Trusted_Connection=yes;<br />
<br />
Provider=SQLNCLI;Server=myComputerName\MYSQLEXPRESS,1433;Database=myDatabase;Trusted_Connection=yes;<br />
Provider=SQLOLEDB;Server=myComputerName\MYSQLEXPRESS,1433;Database=myDatabase;Trusted_Connection=yes;

I've read thru www.connectionstrings.com and I don't think I missed anything, did I?
Did anyone have similar problem before, or have any idea why?
Thanks a lot.

I finally found and fixed the problem. It was my original hunch, that 1433 is not the right LISTENING port (although the setting of SQL Express still points to 1433). To check the port, run cmd.exe and look at the result of "netstat -ano".

Hopefully someone find this useful and don't need to spend days figuring this out.

Hi,
Is there any way to store the unicode characters in sql DB.

I want to store the unicode characters in sql DB and show it back to the user again.

Look into the nchar, nvarchar, and ntext data types.

Yes I tried with nText and stored in database. While retrieve usenig select, it will not return the unicode characters it shows some '?' mark characters.

Expensive Update

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())

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

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

Trouble using DTSWizard.exe to Import data into SQL Database

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.
