Confusing About Connection String Meaning
May 29, 2008
I have some basic skill in SQL Server Management Studio Express already .
But , I still can't understand the exact meaning of ConnectionString.
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database1.mdf;Integrated Security=True;User Instance=True"
code above is copied from a machine-generated app.config.
Questions are:
1.what do [[ | ]] and [[ ]]mean in AttachDbFilename=|DataDirectory|Database1.mdf ??
2.what does User Instance mean? And if this it false, what will happen in my computer.
3.Some string I saw before contains InitialCatalog= Northwood. What are the differences between initialcatelog and attachdbfilename ?
Very thanks

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'm having a BIG problem, this is my 3rd day looking for answer !I'm trying to create a custom membership provider with MS SQL database 2005 but not the default ASPNETDB. I've changed the web.config to be as following:<connectionStrings><add name="sqlConn" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=ASPNETDB;"providerName="System.Data.SqlClient" /></connectionStrings> <system.web><trace enabled="true" /><roleManager enabled="true" /><authentication mode="Forms" />
<membership defaultProvider="MySqlProvider"><providers><remove name="AspNetSqlProvider"/><add name="MySqlProvider" connectionStringName="SqlConn" type="System.Web.Security.SqlMembershipProvider" applicationName="/" /></providers></membership>
But when I try to login to the site using the login control the following error occurs:
Server Error in '/etest' Application.
Configuration Error Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: The connection name 'LocalSqlServer' was not found in the applications configuration or the connection string is empty.Source Error:

It is clear that this is a prblem with my Machine.Config file - since I've "worked!" on this file for a while. But when I've checked the Machine.config file I've found the LocalSqlServer connection it is talking about! .
I'm lost and I dunno what to do, can anyone help?
Here is the mahine.config in case if you need it:<connectionStrings>

I have been trying to host my website on Go Daddy for about 3 weeks and I have cleared several problems but this one remains. I can get into the ASPNETDB database for doing logins , etc but I cant access my database called "PINEmgt".
To try to understand where the problem is located,I built a very simple application without login controls and put on it one Detailform accessing a single line table "Signin". I continually get the error message I got with my real app :"The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty. " There is only one connection string in my app -'PINEMgtConnectionString2'. When I run the app locally on my machine it works. After I move everything to Go Daddy, I get the error message and the following dump"
Line 24: </Fields>
Line 25: </aspetailsView>
Line 26: <aspqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStringsINEMgtConnectionString2 %>"
Line 27: InsertCommand="INSERT INTO Signup(first_name, last_name, email, customer_id) VALUES (,,,)"
Line 28: SelectCommand="SELECT * FROM [Signup]"></aspqlDataSource>
This is indeed the code from my single page app.
The dump is:
[InvalidOperationException: The connection name 'PINEMgtConnectionString2' was not found in the applications configuration or the connection string is empty.]
System.Web.Compilation.ConnectionStringsExpressionBuilder.GetConnectionString(String connectionStringName) +3039085

After Googleing, asking Go Daddy for info (which they dont give) , etc for three weeks, I need serious mental help
in the form of a solution of this problem. Your help with the problem or the name of a good mental health professional in eastern N.C. (maybe both) would be appreciated.

I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.

This is the first time I have used SSIS, so please bear with the ignorance.
I have a super simple package that inserts x000's of rows into a temporary table. The data source is a file that the user will upload. I need to be able to tell the package what file to upload. I'm thinking the simplest thing would be to edit the connectionString property of the SourceConnectionFlatFile at runtime. Is this possible? What form should the file path be in (UNC, other)? And, are there any other considerations I should be aware of?
Thanks!

Good Morning,
I hope that I am just missing a step in the process somewhere. I have established a string variable called DatabaseServer and another called DatabaseName. In the OLE DB connectionstring expression I have the following:
Code Snippet
"Data Source=" + @[User::DatabaseServer] + ";Initial Catalog=" + @[User::DatabaseName] + ";Provider=SQLNCLI.1;Integrated Security=SSPI;Auto Translate=False;"
My understanding is that changing the variable from SERVERA to SERVERB should repoint the connection. (Test to pre-production to production in my current promotion environment.) This should also take effect in any dataflow task using the database connection above right? When I try to repoint the server variable (and only the server variable) I am either a.)throwing errors saying the original connection cannot be found in the data flow task, or b.)the job appears to be processing fine, but the repoint did not take place and data is still flowing to the original server.
Can anyone offer suggestions as to what I am missing?
The properties values in the DB connection:
ConnectionManagerType is OLEDB
DataSourceID is blank
DelayValidation is False (Setting to true changes nothing in my test)
Expression for ConnectionString is (see above)
RetainSameConnection is False
SupportsDTCTTransactions is True (and appears to be unchangeable.)

I was looking at a Miscrosoft example of a SQL "INSERT INTO".
One example they give isINSERT INTO Northwind.dbo.Shippers (CompanyName, Phone)
VALUES (N'Snowflake Shipping',N'(503)555-7233') What does the "N" stand for (or do) in N'Snowflake Shipping'? Is this really needed? I've looked around some and can't find any discussion about it.

Please help me out on log backups.
What happens when 2 log backups of the same db happen simultaneously?
Hypothetically:
One Backup Log job run by SQL Server agent(xp_SQLmaint) every 60 minutes & one Log backup run by Backup Exec every 59 minutes.
Is this a dumb idea and will it cause restore problems based on LSN's contained in the 2 separate backup sets?

heh,heh,heh...cute title, eh? I kill me...
Anyway, The following two select statements return exactly the same results, and utilize exactly the same server resources to run (according to the generated explain execution plans).
The where clause(s) in each are designed to exclude rows that are "empty" according to the designer of the db (don't ask...*rolleyes*).
My question is this...which way would y'all code the select. I have always been "trained" to NOT use negative logic (heh,heh,heh), so originally wrote the select (which, in effect, translates to "get me everything but the empty rows") as:SELECTOSID AS OSID,
[Year] AS QtrYear,
1 AS QuarterNo,
QEPS4 AS EPS,
QSales4 AS Sales,
QInc4 AS Income,
CONVERT(varchar(10), QDate4, 101) AS EarningsReportDate
FROM dbo.RSMsi
WHERE ((QEPS4 <> 0.001 AND QEPS4 <> 0.0)
OR QSales4 <> 0.0
OR QInc4 <> 0.0
OR QDate4 <> '01/01/1900')but in retrospect, I think that's an ugly where clause, and think folks will look at it and think "WTF??? what does THAT mean?". So, I re-wrote the select as if it was looking for the empty rows, then slapped a "NOT" in front of the where clause to negate it in order to STILL say "Get me everything, but NOT the empty rows", as follows:SELECTOSID AS OSID,
[Year] AS QtrYear,
1 AS QuarterNo,
QEPS4 AS EPS,
QSales4 AS Sales,
QInc4 AS Income,
CONVERT(varchar(10), QDate4, 101) AS EarningsReportDate
FROM dbo.RSMsi
WHERE NOT ((QEPS4 = 0.001 OR QEPS4 = 0.0)
AND QSales4 = 0.0
AND QInc4 = 0.0
AND QDate4 = '01/01/1900')whatcha think y'all? It's a style issue, I know...just curious for consensus' sake. Thanks!

I have 5 tables, the first 4 are responsible for getting wines with all their associated info:
Areas - Regions - Wineries - Wines
The last table is an artwork table, and both wineries and wines can have artwork associated with them. How do I integrate a join on the 'Artwork' table for both wineries and wines, taking into account that sometimes (for a single record) there is art for both winery and wine, sometimes for one, sometimes there is none?
I think I understand the 'ON' statement, for instance:
Wineries LEFT JOIN Artwork
ON Wineries.winery_id = Artwork.artwork_winery_id
'and'
Wines LEFT JOIN Artwork
ON Wines.wine_id = artwork_wine_id
But how do I integrate that into the following SELECT statement?
SELECT
area_id, area_name,
region_id, region_area_id, region_name,
winery_id, winery_region_id, winery_name,
wine_id, wine_winery_id, wine_name,
artwork_id, artwork_name, artwork_wine_id, artwork_winery_id
FROM Areas INNER JOIN
Regions ON Areas.area_id = Regions.region_area_id
INNER JOIN Wineries ON
Regions.region_id = Wineries.winery_region_id
INNER JOIN Wines ON
Wineries.winery_id = Wines.wine_winery_id
ORDER BY winery_name ASC;

I have the following scenerio configured in sqlserver -
Windows group Login User Role
domainAuditConfig domainAuditConfig domainAuditConfigUser AuditConfigRole
domainLookupConfig domainLookupConfg domainLookupConfigUser LookupConfigRole
domainuser belongs to both domainAuditConfig and domainLookupConifg windows groups.
When domainuser logs in, he will have both AuditConfigRole and LookupConfigRole roles.
If I reconfigure the above using loginless user, how can the user takes on both roles at the same time?
It seems to me that the user needs to know what role he needs at the time and run the appropriate EXECUTE AS command. Is this true? I can see the benefits of using EXECUTE AS when we are testing our code. But in a production environment, how can the end user know who to EXECUTE AS?
Does it only make sense to use EXECUTE AS from within an application?
Thanks

Dear fellows,
LOP_BEGIN_XACT, LOP_COMMIT_XACT,
LOP_INSERT_ROWS
Labels as the ones are easy recognizable when you explore LDFS by mean DBCC or whatever but on the contrary the following ones are tricky to reach the meaning:
LOP_IDENTITY_TYPE
LOP_DELTA_SYSIND
LOP_SET_BITS
Does anyone have any link related with this? I tried hard to search by Goog or something like that but unsuccessfully at all.

I have a gridview that is very basic and list name, address, ......., and a URL.
If I have this url in the database I have no problem http://www.lubbockisd.org/earlychildhood/
yet when I place this URL http://www.lubbockisd.org/erlychildhood/stubbs.htm
It triggers this error on my localhost server and my production server.
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
I've made changes to datatypes with no success, made sure my length of data type was set long enough with no success.
Which datatype is best for a URL in sql express?
Any ideas why this happens with such a minor change?
Thanks

Hi,I have a table for storing my picture albums here it is:CREATE TABLE [UserAlbum] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [UserID] [int] default(0) , [AlbumName] [nvarchar] (100) NULL , [Audience] [int] default(0) , [Date_added] [smalldatetime] NULL , CONSTRAINT PK_CmmNet_userAlbum_ID PRIMARY KEY CLUSTERED ( ID )) ON [PRIMARY]GO
it has a field called "audience" as the name defines i want to choose who will see my albumsit is integer and as follows:0 value=everyone1=friends only2=private
as i started to write a query for it i came into this problem: for exampleif i write SELECT * FROM UserAlbum where audience=1 then only friends can see the infowhat happens to everyone with value of 0?when i set it to 0, friends should also be able to see the info because it is set for everybody
i noticed i should use "in cluase" like thisSELECT * FROM UserAlbum where audience in ('0','1') > so in this way both everyone and also friends can see the info
or maybe i should add 3 different fields for private,public,friends
it seems to be simple but at the same time harddoes anyone have a suggestion?

Hey everyone,I've got a problem and I can't tell if it's in the stored procedure I'm calling, or it's with the Binding it to the datalist.The error is Syntax error converting datetime from character string.The code it crashes on is:Line 100: //Bind data
Line 101: dg_details.DataSource = reader;
Line 102: dg_details.DataBind();
Line 103: dg_details.Visible = true;
and my store procedure I'm calling is: ALTER PROCEDURE coglej.GetEventsForDate
@eventdate datetime,
@eventowner varchar (50)
AS
IF DATEDIFF(ww,GetDate(),@eventdate ) > 2
BEGIN
PRINT 'Getting EB event price.'
SELECT dbo.events.event_date, dbo.locations.city, dbo.locations.state, dbo.locations.name, dbo.locations.address1, dbo.locations.address2, dbo.locations.zip,
dbo.skus.sku_id, dbo.skus.event_type, dbo.skus.price, dbo.skus.slots_available
FROM dbo.events INNER JOIN
dbo.locations ON dbo.events.location_id = dbo.locations.location_id INNER JOIN
dbo.skus ON dbo.events.sku_id = dbo.skus.sku_id
WHERE (dbo.events.event_date = CONVERT(datetime, '@eventdate')) AND (dbo.skus.owner = @eventowner) AND (dbo.skus.price_type = 'Early')
END
ELSE
BEGIN
PRINT 'Getting regular event price.'
SELECT dbo.events.event_date, dbo.locations.city, dbo.locations.state, dbo.locations.name, dbo.locations.address1, dbo.locations.address2, dbo.locations.zip,
dbo.skus.sku_id, dbo.skus.event_type, dbo.skus.price, dbo.skus.slots_available
FROM dbo.events INNER JOIN
dbo.locations ON dbo.events.location_id = dbo.locations.location_id INNER JOIN
dbo.skus ON dbo.events.sku_id = dbo.skus.sku_id
WHERE (dbo.events.event_date = CONVERT(datetime, '@eventdate')) AND (dbo.skus.owner = '@eventowner') AND (dbo.skus.price_type = 'Regular')
ENDWhat's cause the crash are the quotes around @eventdate. However, without them, it doesn't return all the rows (if any) and if I have them in, I get this error. The odd thing is that when I copy and paste one of the SELECT statements into the VWD sql window and replace the variables with the same values I'm using at runtime, everything runs fine.Anyone have any ideas?Thanks in advance,--Joel

Hi,
I have a SQL2k STD with SP3 installed.
Currently, only one database db_XYZ is there. The server has been started up since 07/03/2003 16:00 pm. But in the sql server current log: "Starting up database 'db_XYZ'." info is spreading from that time (16:00 pm) to this morning 10:00am at an interval from every 1 minute to 4 minutes.
Why need to 'Starting up' this database so much times?
This reminds me that this 'Starting up' is kind of 'abused' in many other servers. Any idea?
thanks
David
