So here's the situation: I'm creating a front-end application to an SQL Server 2000 database and I need to create a new login to the database for the app.
Is it possible (or even; is it a good idea...) to create a logon that only has access to a single table?
Actually, I know it's possible - but I don't want to have to go through the hundreds of tables and deny access to them all! So I guess the question is;
Is there a quick and easy way of granting a login permissions to a single table only?
Hi everyone, not sure if a this topic has been covered yet (a have been looking all day), but as I am still very new to this, my problem is as follows:
In the Try .. Catch block below, data is posted from a form and the SqlCommand.ExecuteScalar() statement returns a Unique Job ID.
I am attempting to populate a subordinate table for qualifications which are selected from a ListBox, but rather than using qualification titles, I am using the values.
My problem is that only one value (the first) gets posted multiple times, when multiple values are selected.
Looking at the For Each loop in the inner Try Catch block, I am wondering whether there is some sort of Index pointer that needs to be incremented, in order to establish new values further down the list.
I have seen no evidence that this is the case, save for the fact that the value stalls on just the first.
Any help would be appreciated.
===== CODE ===
Try
C4LConnection.Open()
JobPostingID = SqlJobPost.ExecuteScalar()Response.Write("<br />Selected Item: " & Qualifications.SelectedItem.Value)
Try
' Multiple Qualification EntriesSqlQualPost.Parameters.Add(New SqlParameter("@JobPostingID", SqlDbType.Int))
SqlQualPost.Parameters("@JobPostingID").Value = Int32.Parse(JobPostingID)SqlQualPost.Parameters.Add(New SqlParameter("@QualificationID", SqlDbType.Int))
SqlQualPost.Parameters("@QualificationID").Value = Int32.Parse(Qualifications.SelectedItem.Value)
If Qualifications.SelectedIndex > -1 ThenFor Each Item In Qualifications.Items
If Item.Selected ThenResponse.Write("<br />SelectedItem Value: " & Qualifications.SelectedItem.Text)
QualPostingID = SqlQualPost.ExecuteScalar()SqlQualPost.Parameters("@QualificationID").Value = Int32.Parse(Qualifications.SelectedItem.Value)
Response.Write("<br />Selected Item: " & Qualifications.SelectedItem.Value)
End If
Next
End IfCatch Exp As SqlException
failJobPost = True
lblError.Visible = TruelblError.Text = "Could not add qualifications <br />" & Exp.Message
End Try
failJobPost = FalseCatch Exp As SqlException
failJobPost = True
lblError.Visible = TruelblError.Text = "Error: could not post job to database <br />" & Exp.Message
Finally
C4LConnection.Close()
End Try
With the Synonym, I was encouraged to separate my db to several smaller dbs, like base,dynamic,static and security. Now I am trying to use mirroring, I see it may cause problem, I think I need mirror all them to another server. My question is when the server is down, will all db switch to mirror server in the same time? And one can manually set which db is the principal db, but in my case, it will not work if principal server of all four dbs are not the same.
Any thought?
thanks

Has anyone managed to crack getting multi-select parameters to work from an SSRS 2005 report which is querying an SSAS 2000 cube.
SSRS 2005 does support Multiselect, however SSRS 2000 did not. Given that i am querying an SSAS 2000 cube, i get the impression that i am also limited to SSRS 2000 functionality regarding to multi-select parameters.
Is there anyone out there that ever managed to get a wor around, say by using filters on a table or anything really that coud simulate the same behaviour....

Having an extremely frustrating issue trying to connect to SQL once I've done the NET START MSSQL$SQL_DEV /c /m /T3608.
Briefly: SQL 2K and 2K5 named instances running on same DEV box. Can't open admin:<serverinstance> in SSMS, I get the following error:
"Login failed for user 'sa'. Reason: Server is in single user mode. Only one administrator can connect at this time. (Microsoft SQL Server, Error: 18461)
This happens regardless of credentials supplied (my AD acct (local admin on box), AD acct running SQL services or sa). Object Explorer is closed, remote connections disabled in SS Surface Area Config. I open SSMS and make no attempt to connect to server. Choose File >New > Query with Current Connection. In dialogue box, I attemp to utilize DAC and get the above error.
In DOS prompt where I issued the single user mode startup cmd, try to use sqlcmd to grab DAC session and receive the following error:
SQL Network Interfaces: An error occurred while obtaining the dedicated administrator connection (DAC) port. Make sure that SQL Browser is running, or check the error log for the port number [xFFFFFFFF]. Sqlcmd: Error: Microsoft SQL Native Client : An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections..
So, no matter what method I use, I've managed to disable ALL access to the instance, despite the tips I've seen here and on Google.
I need to move the system databases to new disk volume, but cannot do so until I can open a connection to the instance once I've put it in single user mode. Looking in the SQL Srvr log following startup in single user mode I see the following:
Message
Server is listening on [ 'any' <ipv4> 3560].
Message
Dedicated admin connection support was established for listening remotely on port 3560.
Do I need to call the port# specifically when using SSMS or sqlcmd?
I can include screenshots of the failures and mssgs if necessary.
More disturbing is in a DR situation, I CAN'T OPEN A SESSION TO THE INSTANCE, which would be a very bad thing...
Please Help!
Hi,
I'm currently writing an windows application where a LOT of threads connect to database and send small amount of data.
I'd like to ask you for the best approach to do it.
The way it's implemented now:
Each therad uses it's own SqlConnection sends few bytes of data and closes the SqlConnection. Each thread has to send initliazation data which i guess is few times bigger then accual data and then it has to close connestion even more bytes that could be avoided are sent.
The way i'd like it to be:
There is only one SqlConnection all therads share it. It's opened when the applications starts and closed when it's application is closed. This way i send initialization data only once and by doing this i can save some bandwidth.
Does SqlConnection operations has to be in critical area? Can it be used pararelly by many threads? Maby there is better way to do it? Is it recomended to close SqlConnection as soon as possible after query? If so why?
Thanks in advance,

Hi,
I have Windows XP Home Workgroup LAN.
I am treating one of the XP Home system as 'Server' and installed SQL Express 2005 SP1. Enabled remote connections access.
I have total 4 XP Home systems, out of which one i am treating as Server, from the rest 3 computers, 2 are successfully connected to the Server and able to access SQL Express without any problems. But the 3rd system is unable to communicate with the Server. I disabled all firewalls in this 3rd system but still unable to connect to the server. I am able to ping the server, browse for shared folders on the server. Except SQL Express remote connection, everything else in the network is accessible from this 3rd computer.
Can anyone help me on how to troubleshoot this 3rd computer sql express connection problem to the server.
I don't have any error message to provide here. It just says, unable to connect to sql server, verify username/password etc.
Is there any limitation on SQL Express remote connections ?
I'm trying to insert data into a table from two tables into a single table along with a hard coded value.

I get the following-

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.

Hi Everyone,
I have set up a link from ACCESS to a SQL 7.0 database using ODBC (File DSN saved on a shared DRIVE). The link works well only from the workstation where the link was created. But How can I create a link so a group of users can view the linked table in ACCESS without type a password? Any suggestion is appreciated.

Is there a way to specify a MS Access table (or query object) in the select query of SQL Server.
Ex.:
MSAccessTable (in file.mdb)

col2
a1

b1
b2
SQL query in SQL Server:
SELECT col1, col2 into SqlTable from [file.mdb].MSAccessTable;

I have table "Clients" who have associated records in table "Mailings"
I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting.
I'm trying to return records containing the next upcoming mailing for each client.
The closest I can get is below:
I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date'
SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN
dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id
The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..
I've managed to BCP in a single table form a backup DAT file into a database, but it took WAY to long (1 hour+ on a meaty server) and I can't understand why.
The table only had a few rows of data and only had a few small dependancy tables.
The table has a primary key, hence an index so the BCP becomes a logged operation but it still should not take this long.
Here is the BCP command line that I ran :-
bcp <dbname>.dbo.<tablename> in <DAT filename> /U sa /P /S <server> /m 1 /n
Could anyone please shed some light on this. Is there anyway of 'fast' bcp'ing this table into the database overwriting the existing one.
Failing that, is there any way of scripting the transfer of a table from one server to another.
Many thanks.

Does anyone know of a way to restore a single table using SQL 7.0? I know that I can build a dummy database and do a database restore, then copy the table from database to database. But....was wondering if there is a way to restore a single table from a backup. Is losing the ability to restore a single table one of the 'features' of 7.0?

How can I restore just one table from the full backup? It was very easy with 6.5 but I am not sure whether it's possible with 7.0 and if it is possible, how to do it.
Thanks in advance.
I thought I had posted this question already, but didn't see it in
the list. I apologize if this is a repost.
I am running SQL Server 6.5 SP 4.
I am attempting to load a single table from backup, but continually get
the error about schemas not matching. Interestingly, it comes back with
a status 4, and not the status 3 indicating a mismatch on Ansi_Padding.
The statement I am using is
load table demhist from internal_tape with file=5,nounload
I have tried creating the table from scratch and using select * into...
I have tried both above with both settings of Ansi Padding. The table
I am trying to load contaings char columns which allow nulls. I have
experimented with loading 2 other tables. One of the other tables loads
and one doesn't. The one which does not load also has char columns which
allow nulls, while the one that does load does not have char columns
which allow nulls.
Is it a known problem or limitation on the table load that it cannot reload
tables that contain char columns which allow nulls?
Hi!
This morning, I needed to restore 1 table to a database because it had
accidentally been deleted (don't ask). Each time I tried to restore the
single table, I would select TOOLS| DATABASE BACKUP/RESTORE| RESTORE
tab from Enterprise Manager, then I select SINGLE TABLE, but am only
given the existing table names as choices to restore. This happens when
I select to restore 'FROM DEVICE' as well.
Am I doing something wrong or is this how MS SQL6.5 is supposed to
work? Am I only able to restore a corrupt table and not a missing
table? I ended up restoring the entire database...
Thanks for your help!

It appears that in SQL 2000 restoring a single table is a bit more tedious and less user friendly as in earlier versions (6.5). Can anyone explain in a nutshell the easiest/quickest way to restore a single table from a backup?

Hi all !
I have a table with no keys (temp table) which looks like this :
col1|col2|col3
001|A|.087
001|B|.032
001|C|.345
002|A|.324
002|B|.724
003|A|.088
003|C|.899
001|A|.087
001|A|.234
001|B|.032
As you see, there is some duplicate entries in it. I would like to get a list of all the rows that have the same col1 and col2 BUT different col3 value. The result should return col1=001 col2=A but NOT col1=001 col2=B. I tried a lot of queries with EXISTS, HAVING, etc... but nothing seems to work.
Anyone have an idea how I can do it ?

View 2 Replies View RelatedWe have one user who enters a transaction and then does a single rowupdate (updates all columns but only one is changing - this is due tothe way our sql is generated in the application), at this pointanother user enter a transaction and tries to update the same row (heunderstandably has to sit and wait while he is blocked by the originaluser). The original user then updates the same row again – at thispoint the second user is chosen as a deadlock victim and killed. If Itry and recreate this with any other tables(or pubs) I get my expectedbehaviour of the original user just doing 2 successful updates and thesecond user then completing his update once the original user haseither committed his changes or rolled back. The query plan indicatesthat a drop and insert of the row is happening (this is not the casewith any other tables where we get our expected behaviour). This onlyhappens when the index is clustered - if we use a non-clustered indexit does not occur.Is this expected behaviour? it seems dangerous to me as the firstuser has not commited or rolled back his updates. It was onlyhighlighted by a fault in our application that caused the secondupdate to be executed.I have some thoughts about it being something to do with a row lockbeing relased due to a delete / insest of the row in the second update(we see this in the execution plan).....Any help much appreciated as I am struggling to get my head round howthe second user was ever able to get hold of the resource.

Hi,
I need to display the datas in a table format. I have placed a table and now i need to use two different datasets for a single table. Those two different datasets are generated based on two different stored procedures. Those stored procedures retrieve data from two different sql tables.

I was writing a query to get the age and the retirement year for all the employees.And thought of using while loop so that I don't have to write IF conditions or case statements for all the ages.
I'm using the AdventureWorks2012 database.And the actual table looks like this.
SELECT * FROM HumanResources.Employee
*NOTE:- These tables are not the complete tables.
BusinessEntityID         JobTitle                 BirthDate       MaritalStatus     Gender
      1                Chief Executive Officer           1963-03-02  S              M

     4             Senior Tool Designer              1969-01-23           S             M
[Code] ...
And after I wrote the query to get the age and the retirement year of all the employees I got 70 tables for all the ages from 30 to 70. As the starting age is 30 and the last age is 70 in the table.So,I just want to know how I can settle all the tables into a single table as a sinle result and not as multiple results.
The query for age and retirement year....
DECLARE @Counter INT
DECLARE @Duration INT
DECLARE @Result DATE
SET @Counter=(SELECT MIN(DATEDIFF(YY,BirthDate,GETDATE()))FROM HumanResources.Employee)
SET @Duration=30

And the result tables.
