I know in ASP one could looop through the collection using For Each
like below to see all the connection options. How do you achieve this
in ASP.NET?
for each item in
objCNN.Properties intCTProps = intCTProps +
1 Response.Write "<tr><td>" & intCTProps
& "</td>" & vbCRLF Response.Write
"<td>" & item.name & "</td>" &
vbCRLF Response.Write "<td>" & item.value
& "</td></tr>" & vbCRLF next
Can anyone point me to a comprehensive list of the options available in connection strings? I know that a lot of the options are able to be set elsewhere, but I'd like to have a complete listing for interests sake.
Thanks
There are a few questions I have on the parameters you can use in a connection string. I didn't see a post with these already, and I think they may be helpful for those just starting to figure out how things work. I couldn't seem to find these defined in the msdn anywhere. What exactly do the following do:
"server=.\sqlexpress;" or "data source=.\sqlexpress;" - Is there a difference in using these, or are they completely interchangeable without any side effects? So far it seems I have been able to swap them for each other without anything happening however there may be something I don't see happening behind the scenes!
"Trusted_Connection=yes;" - Is this a workaround for getting SQL Server to work on vista's UAC or something? If not what does it do?
"Integrated Security=true;" - I know this has to be used with User Instance=true, but is there anywhere that says what it's actual function is?
"database=myDB;" - If I use this in a string it causes my program to crash. It also has a side effect of making me have to stop all sqlservr.exe processes and restart the service before my program will run again without it included in the string. Not sure why this is the case, however here is the string I try to use:
Code Snippetstring connStr="server=.\sqlexpress;AttachDbFilename="c:\sfsf\sads\myDB.mdf";database=myDB;Trusted_Connection=Yes;";
Now with using that string, the point of having both the "AttachDbFilename="c:\sfsf\sads\myDB.mdf";" and the "database=myDB;" options is that I read if you use those together it causes the SQL Server to first check and see if the database is already attached. If it is then it doesn't reattach the database, and just uses the current attached database. While this makes sense it doesn't seem to work for me since as I stated above anytime I use the database option it crashes the app. Any ideas? If that isn't how it is used what is the "database=" option for?
There may be more options I don't know about yet, but those are the ones I am not clear on. Hopefully one of you more experienced folks and shed some light on them!
Hi,,
when I open a connection to SQL Server 2005 (c#, VB.NET 2005, SQL Native Client) these setting are set (can see it in Profiler):
-- network protocol: TCP/IP
set quoted_identifier on
set arithabort off
set numeric_roundabort off
set ansi_warnings on
set ansi_padding on
set ansi_nulls on
set concat_null_yields_null on
set cursor_close_on_commit off
set implicit_transactions off
set language us_english
set dateformat mdy
set datefirst 7
set transaction isolation level read committed
I would like ARITHABORT to be ON. Have tryied to set it as a defaul in my database, but still the connection has OFF at this setting.
How can I force my C# code to set this option to ON during connection opening?
Thanks,
Przemo
I need to set multiple values for some SQL statements, for exampleSET NUMERIC_ROUNDABORT OFFGOSETANSI_PADDING,ANSI_WARNINGS,CONCAT_NULL_YIELDS_NULL ,ARITHABORT,QUOTED_IDENTIFIER,ANSI_NULLS ONGOin a .sql file, but would like to reset them to their previous settingsagain for other SQL statements. I didn't find anything in books online. Ithought just calling "set" was enough, but apparently not ....Thanks.

In my project , we are using Dsn and DSN less connection, for certain functionality
we are providing users to select tables and views .
we don't want that all system tables and views are listed for selecting , how can we achieve this functionality?
Is there any options in the connection string for restricting system tables and views?
Any help is much appriciated
Thanks

I have added several SqlDataSource controls to my C# project, but when I try to configure them, there seems to be a lot of greyed out buttons. Either the WHERE, ORDER BY, and ADVANCED buttons are greyed out, or when they are active, the ADVANCED button always displays the advabced options which are always greyed out. I doesn't make any sense to me. Please explain (in baby language please)
View 4 Replies View RelatedI've added an SqlDataSource control to my web page and selected "Configure Data Source" on it. This brings up a "Choose Your Data Connection" wizard, and it asks you to select from a dropdown list of presumably pre-existing connection strings in my web.config file. However none of my connection strings will display in that dropdown list. The only thing i can do is hit the "Create New Connection" button and this adds yet another connection string to my web.config file. I've already ran through the wizard once, created a new connection string, but when i run through the wizard again, even the new connection string - the one created by the last wizard will not appear in the dropdown list. Any suggestions? Jason

View 2 Replies View RelatedHi ,
I could do with a couple of pointers to the best options to acheive my goal, I'm pretty close with the way I've done it, but I feel there is a more elegant solution out their so your help would be most appreciated.
The problem is finding the best way of moving some SQL Server 2000 changed data into sql server 2005. We are only interested in some tables in 2000 (and sometimes just subsets of those). Because there are quite a few tables and the we want to set up a schedule to run periodically, we chose SSIS. The main reason for this is to utilise a for each loop that pulls each tables name from a one column staging table of table names. (that way we can do more or less comparisons by simply adding and removing from the staging table) Also in this loop, using the table name as a variable, we run an exec sql task along the lines of 'SELECT * from varTable EXCEPT SELECT * from varTable_tracker' which gives us the difference beteween the two tables (where the tracker table is a copy of the data table which is sychronised at the end of the job run). So far so good. Now the tricky bit, EXCEPT only works under 2005, the tables are in 2000 so we ended up having a linked server in 2005 back to the 2000 table. Is there a way of acheiving the same result without involving the linked server - or is there a task (script?) we can run to verify the linked server is up before we excecute the job -we already run checks on Connection Managers to see if they are up but never tried linked servers? Lastly, will performance be an issue
Thanks
anyone know about the undocument options of DBCC?
which options are undomented?
i.e.
log
There are only a few options which are documented in SQL Online Books
thank in advance
Is it necessary to reinstall SqlSvr 6.5 in order to chance
from 'per server' to 'per seat' licensing ?
SQL 6.5
What are the most critical "dbcc" options that should be run to insure the sanity of database and DBA alike? Do these have to be run in single user mode or can they be run while users are on the system?
Thank You.
An automatic monthly delete has recently grown from 15 to 20 million rows. It is now filling my 70GB T-Log completly. I don't have any space to expand the T-Log. Do I have any options other than reducing the number of rows in the delete?
View 2 Replies View Relatedhey guys, i need your help please.
here is the scenario:
1. I need to return a data back to client (result set varies 20-10,000)
2. I only want to show 20 records at a time
3. To get info i need to display i need to join 10 tables
When there are small #s of records it works but when i get over 8000 then it becomes a problem:
1. The first version was:
Get all data using big query and return everything back to client and display only 20 at a time (not very proficient).
Takes around 15 seconds to view 20 records.
2. Inspired by 4GuysFromRolla (http://www.4guysfromrolla.com/webtech/062899-1.shtml)
Use Stored Procedure w/ server side paging logic to get 20 records at the time. I had to pass every filter parameter and stuff. SP had to sort resultset and return only 20 records i need to display.
Takes around 5 seconds to view 20 records.
I still think it's slow, i know this is a very broad question but is there any other way to do it, logically?
Any help is appreciated.
Wojo.
Hi folks, Recently i've installed a fresh Installation of Opertaing Sys and SQL.
Win 2000 server, sp4
SQl 2000 Enterprise, sp3.
I am using Domain user service startup for sql and is member of domain admin. I've manually added the user in Local-Admin group of the system. Obviously it's also has Sys-Admin server roles.
The problem is; when i use enterprise manager and change any of the server settings; Priority Boost or Fix Memory Allocation for the Sql server, nothing happens, the options dialog box closes and doesn't ask for restarting the server neither does the settings take effect when i restart SQL.
However if i change the settings using sp_configure using the same user; it works. i've assigned a fixed memory to SQL but the option "Reserver Physical Memory For SQL" won't work. Couldn't find this option in SP_Configure.
Any ideas, what has gone wrong.
Hi all,
This follows on from a query I had a few days back (and for which I was promptly flamed! However, I've got skin like a rhinoseros, so here goes...)
I have a table - ProjectSite - that is pulling information from a two tables (Project and Site). This table contains data regarding which sites are part of which project.
I now want a means of reporting dates against this. The problem is that each project has bespoke milestone dates, so I can't just create columns in ProjectSite. The only solution I can see is to pull each project (and there's quite a few and its corresponding sites into a new table) and then I can create my bespoke columns.
Does this sound like the best viable option, or can anyone suggest another means of doing this?
TIA,
SamuelT
Hello all,
I am considering the different options for package deployment on the server.
Until now, I have found several different ways to deploy packages to the server (File System):
Using the Import option from the Management Studio (only one by one)
Using the Deployment Utility (Needs building the whole project. Opens all the packages in debugging mode, cannot deploy to different folders)
Using the dtutil by constructing a command line for each package deployment. (complicated)
Simply copying the files from the local project folder to the "Program FilesMicrosoft SQL Server90DTSPackages" folder on the server.
Does anyone have any other suggestions for deployment?
The 4th seems to be the easiest one, but I seen anybody suggesting such an action. What's the downside of such an action?
Thanks,

I hoipe someone can point me in the right direction here.
I have an application with the following requirements (using SQL CE 2 alas)
A set of tables on the server that need to be imported to the handheld. Using rda, I need to get the modifications to these tables from the server (add/edit/delete) but the handheld will never update these tables.
A set of tables on the server that need to be imported to the handheld. The handheld needs to add/edit existing records, and it needs to get any changes from the server.
A set of tables on the server where the handheld needs to import a subset of the records. It needs to add (but not edit) new records, upload the new records to the server, and download any changed (add/edit/delete) records to the handheld.
What tracking options should I use in these 3 cases?
The problem comes in that I need to have some foreign key relationships in the database on the handheld. Since rda munges the names of primary keys (and indexes), I do not know of a good way to add these foreign key constraints. Any suggestions?
Thanks
Hello all. I am currently doing some research into options for
setting up reporting. Right now we have a server on EE that's
getting hit a bit too hard by the reports. The budget is
currently a bit low, but we already have a second server
purchased.
For our reporting, we need data that is up to date within the last 15
minutes (less if possible). Because of the potential size of some
of our transactions, I've ruled out log shipping as being too much
downtime of the reporting data while the second server is catching up
to speed. So, I'm trying to figure out what reporting options I
have left open to me.
1) I understand that for reporting purposes, a snapshot must be taken
of the mirrored server. Why are reports not able to run directly
off the mirror live (or am I mistaken?).
2) Is it possible to mirror from EE to SE (remember, low budget for the second server)?
3) How high is the overhead when doing a snapshot every 5-15 minutes (
I would think it's machine specific, but overall is it pretty quick or
prohibitive based on how often the snapshot would be needed)?
4) Is replication perhaps a better option based on how up to date the
data has to be? Are there any other options that may be available
for near-realtime reporting?
Thanks in advance for your time.

Sorry I am a newbie in SSIS.
I have got a small project that requires to feed in a .CSV flat file and load the data into SQL server 2000.
I developed a SSIS package for this and get it working in my computer, but I need to deploy it to customers that they don't have VS 2005 or SSIS installed. May any one of you give me some clues on that?
I played around with the flat file deployment and again it seems only working on my computer as I have everything installed.
Hello all,
Just wanted to get some feedback on this scenario. I will be developing an ASP.net application for our local intranet that employees will have access to. It may also be implmented to allow employees to access this ASP site from home as well. I would be using SQL Server 2000 as the backend DB and wondered what type of licensing would best fit this scenario?
Sorry if this is double posted....seemed to be having some issues with posting.
Thank you!
I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?
Hi,
I was recently experiencing a slowness when executing stored procedures from a .NET Application, but it went fast when executing from Query Analyzer. Research led me to find that by turning ArithAbort ON that it forces the SQL Server to use the same Execution plan whether the request is coming from Query Analyzer or the Application.
My concern now is the effect of ArithAbort. I understand what turning this option does, but I am trying to think of a scenario where turning it on could be bad. Does anyone have any suggestions on what I should be aware of when disabling/enabling ArithAbort or ArithIgnore?
Thanks.

Morning all,
I'm writing an Insert form which will write records to a few tables. What I want to know is how do I write multiple answers to one question in different rows in the table but keeping the ID?
For example.
The form has the following fields:
HotelIDHotelFacilities (CheckBoxList)
Now each hotel (in this case) will only have one ID but more than one HotelFacility .
How do I get my table to read...
HotelID
HotelFacility
1
Bar
1
Restaurant
1
Cafe
1
Wi-Fi Access
I presume INSERT INTO tblHotelFacilities(HotelID, HotelFacility) VALUES(@HotelID, @HotelFacility) won't write more than one selected facility?Thanks,Brett
Advanced SQL generations options:
generate INSERT, UPDATE, and DELETE statements is all greyed out?
in my sql data source control.?
I have made a brand new instance with sql server management express....have I missed something?
We have an intranet site (.NET 2.0) that needs to access to a SQL Server 2005. We've created a named user on the server, WebUser, and use it's credentials in the connection string to connect to the server.
Due compliance issues, we're being asked to remove all the named users from the server. Now the users will have to connect to the database using their security context. That means all the users need to be in some server role, should be given access to the server, etc which is a security risk and a maintenance nightmare.
What other alternatives do we have to solve this problem?
Your help is much appreciated.
Is it possible to leave this parameter (max server memory (MB)) on default(2147483647) if on my Cluster I have Oracle, Lotus Notes and some other things running, or I have to calculate the amount of memory SQL Server needs?
