changing connection string from one sql server to another using vb .net

I have developed numerous reports in a vb .net app (Windows Database App)
that is
soon to go into production. When I built each report, CR connected to sql
server on my development platform. The connection string is different than
it will be at my client.
How can I change the connection string so that it recognizes my client's
server instead of mine for each of these reports? This is not technically a
sql server question, but I am hoping some of the sql developers who review
these posts will have run into the same issue,
Thanks for any help.

changing a query

This is my current query that I have in an App I wrote:
MySQL = "select DateEntered,Shipper,PickupDate,PUTime,City, State, Zip,
Consignee, Destination, DState, DZip, PickupNumber, ShippersNumber,
PONumber, Consignee_Ref_Number, Weight, Number_Packages, Carrier,
Carrier_Number, Trailer_Number, ApptDate, ApptTime, IDFProNumber,
DeliveredDate, DeliveredTime, FreightCharges, TransitTime, Comments,
LastUpdate, lastcomment from IntermodalTracingMasterFile where " &
tmpMyShippers & " Order by [" & strSort & "] desc "
This works fine.
I need to modify it a little I need to have one query that will return when
the DeliveredDate is empty
and anohter query to return the ones that have somethign in the
DeliveredDate field.
Thanks> the DeliveredDate is empty
If by 'empty' you mean NULL, you can add the following to your WHERE clause:
AND DeliveredDate IS NULL
For non-null values:
AND DeliveredDate IS NOT NULL

Change Table Ownership.

I have a DB that I moved to another server recently and in the process we
created a new user/pass combination.
All the tables for the main app are listed as "system" and the main app runs
great.
There is a secondary app using 12 tables in the DB and although we changed
the user/pass in the app and it connects fine the app won't run saying
"Invalid object name 'tablename'."
The table is there. The only thing I notice that seems odd is the tables are
listed as "user" and not "system" and the user assigned is the old user.
How can I either,
A. change what user owns the table? or,
B. Change it from a "user" table to a "system" table?
Thanks for any replies.

Have you tried explicitly naming the object? e.g. dbo.tablename?

Change SQL Server query optimizer locking

Hi,

Our app has been distributed on more then 300 different sites.
On one of the sites we get the error "Could not continue scan with NOLOCK due to data movement" indicating that the query optimizer takes a NOLOCK for our select statement ( has been opened with adOpenDynamic, adLockOptimistic ).

It's no option to change the source, we have to solve this without touching the code.

Is there any way to tweak the query optimizer so that our app works correctly?
I know that there will be a reduction of performance but it's our only choose.

thnx in advance,

adOpenDynamic, adLockOptimisticCan you reproduce the same behavior in a lab machine, or only on site?

-PatP|||On our test environment it happens once, then it continues correctly.
But on site the problem is persistent.|||Using NOLOCK on highly voletile data in cursor-based situations is not recommended. What you're experiencing is very typical in high activity in terms of action queries. You will have to change your cursor and lock types.|||I'd suggest fixing the cursor, or trying to run the query at a very low (preferably zero) usage time of day for the tables involved in the query.

Change SQL (order by) at runtime?

I'm creating a fairly simple report using the ReportViewer control in
a Windows app. I have credentials and everything working, but I want
to change the SQL at run time. The dataset in the designer has this
SQL:
Select * from CPS.Main Order By Docket
Easy enough, but how can I replace that Docket with something at
runtime. I tried
Select * from CPS.Main Order By ?
and passed in a parameter. It runs, but ignores the Order By.
Am I going about this the wrong way? It's an ODBC database, not
SQLServer if that matters.First, one option for you is to allow the user to sort as they want. User
sortable columns is availabe starting in RS 2005.
Otherwise, what you want to do is to set the data source as an expression.
You are creating a string that equates to the SQL you want.
= "Select * from CPS.Main Order By " & Parameters.MyParam.Value
Be sure you have the field list you want because once you switch to this you
will not get a field list refreshed.

Not option one, each page is a separate law case, the Order By will be
putting those pages in some sort of order.
I was about to tell you that your second approach doesn't work,
because the red ! in the data tab of the designer (VS2005) is greyed
out, but it does work when switching to the Preview tab.

change mdf to sql authentication

I have a web app, designed using VWD Express and using SQL 2005 Express. It has a mdf database called "client". It was created using security of windows authentication. I have already changed my instance of sql server express to accept mixed windows and sql authentication.

How do I change my "client" database's permissions to the sql authentication? I need to add a user name and password as a requirement for my web host to be able to attach the mdf to their instance of sql 2005. It has to be the same user and password as I use with my web host's sql server 2005.

Thank you in advance.

Hi mlg74,

Not very sure what you mean. Do you mena that, since you are going to upload your database to web hoster, you want to create a sql user name and password for your database?

If my understanding is correct, based on my understanding,you have no need to do that. Database authentication is managed by database administration tools, not your database file itself(the mdf file).So, you can just upload your mdf file to the web host and ask for a sql user name & password.

BTW, since you were using windows authentication before, you need to modify your connection string after authentication mode changed to "sql authentication". You can do that by simply remove "Intergrated Security=True" and add "User ID=username;Password=psw".

Sample: <add name="constr_name" connectionString="Data Source=Server IP;Initial Catalog="DatabaseName";User ID=User Name;Password=PSW"
providerName="System.Data.SqlClient" />

If you also want to use sql authentication mode on your local machine, make sure you have sql management studio express downloaded https://www.microsoft.com/downloads/details.aspx?familyid=C243A5AE-4BD1-4E3D-94B8-5A0F62BF7796&displaylang=en. You can create a new sql authentication name/password through Security-->logins-->New logins in Management Studio Express.

Hope my suggestion helps

|||

I know you are right, but my webhoster obviously doesn't know what they are doing. They told me I had to have the same usr name and password on my local machine as I do on the sqlserver 2005 on their server. But I am using windows authentication on my local express edition, but they said I had to make the passwords match anyway. The first time I uploaded the database files to the server for them to attach, I could no longer access my database on their server. So that's when I changed my authentication to mixed mode and had them re-attach it. But your saying it makes no difference, becasue those values are not stored in the .mdf, or .ldf files at all.

What I did to finally make it work, was after they attached it, again I could not access it on their server. So out of frustration, I deleted it off their server and was going to start over. But when I created a new db on the server, I used the same password and username, and when it created, it was my attached db files, so I was happy! That was weird, and it's odd, how some webhosters dont know how to handle sql server 2005.
