Linked Table Is Read-only, But Why?
Apr 17, 2008
I work on an MS Access project ( *.apd - file) that is linked with a
SQL-express server 2005 (local installed). On this server are 2 databases x
and y.
I linked some tables of database x to y and here's the problem: the linked
tables are read-only.
My authentication for the server is Windows authentication and I'm
administrator.
I say this because I think the problem is a security problem.
when I try to change data in the
linked table in Microsoft SQL Server Management Studio Express, I get now the follow error:
---------------------------
No row was updated.
The data in row 12 was not committed
Error source: .Net SqlClient Data provider.
Error Message: Transaction context in use by another session.
Correct the errors an retry or press ESC to cancel the change(s).
---------------------------------
All other programs are close, except MSE
thanks a lot!!!!!
Can somebody help me to make the linked tables are not read-only? What is
the problem, what did I wrong?
Thanks a lot!

Hi,
I have an Access database Front End which use SQL server as a Back End. The two are connected using ODBC. Occasionally, some of the linked tables in Access go read only. I can't add or edit records. The only way I know to get round the problem is to delete the link and re-create it. Refreshing the link does not work. Can anybody suggest why this would happen, and the best way to fix it when it does occur?
Edited 12:10 06/14/07
Some extra info. At the same time it goes read only, the link loses it's primary key.
Thanks
Colin

I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below:
EXEC sp_addlinkedserver
@server = 'test1',
@srvproduct = 'Oracle',
@provider = 'MSDAORA',
@datasrc = 'testsource'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'test1',
@useself = 'false',
@rmtuser='sp',
@rmtpassword='sp'
When I execute
select * from test1...COUNTRY
I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?
Thanks a lot.

Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew
If jdoenew is missing in the 2nd db I will need to write entries like:
db1.usr_table.usr_name = jdoenew
db1.usr_table.password = tmppassword
db1.usr_table.active = 1

Hey ,
I have sql server 2000, and i am using Microsoft Application block.
I have Transaction Like...
SqlConnection conn = new SqlConnection(ASLConnectionString); conn.Open(); SqlTransaction Trans = conn.BeginTransaction(IsolationLevel.ReadUncommitted);
But If i have another process that try to read the Table if that old transaction running.. it wouldn't Allow me to read the DATA.
i tried Isolation level "snapshot" but that works under sql server 2005 only. so i can not use that. And i have some services that will run during day time.
So if anybody have solution to read the data from table...from sql server 2000 even if another transaction is running?
Please Give any guideline..Help will be appriciated.
thanks & regards,

Hello,
I was wondering how to make a table read-only. I want to make a script that creates a table, adds some data to it, then makes the table read-only to prevent someone from accidentally changing the values.
Thanks to anyone who can help,

Strange one here - I am posting this in both SQL Server and Access forums
Access is telling me it can't append any of the records due to a key violation.
The query:
INSERT INTO dbo_Colors ( NameColorID, Application, Red, Green, Blue )
SELECT Colors_Access.NameColorID, Colors_Access.Application, Colors_Access.Red, Colors_Access.Green, Colors_Access.Blue
FROM Colors_Access;
Colors_Access is linked from another MDB and dbo_Colors is linked from SQL Server 2000.
There are no indexes or foreign contraints on the SQL table. I have no relationships on the dbo_ table in my MDB. The query works if I append to another Access table. The datatypes all match between the two tables though the dbo_ tables has two additional fields not refrenced in the query.
I can manually append the records using cut and paste with no problems.
I have tried re-linking the tables.
Any ideas?
Thanks,
Brad

I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.
Thanks in advance,
Mark

SQL Server 7.0 (SP1)
Error:
------
OLE DB provider 'SQLOLEDB' supplied inconsistent metadata. An extra column was supplied during execution that was not found at compile time.
A column was deleted from the a table on the linked server and now this message appears when using the linked server definition to access the table. Deleting/Recreating the Linked Server has no effect. I found an earlier note on this...but it just kind of ended with no resolution. Anyone have any thoughts on this now.
Thanks for any input.

Hello
I'm working on a package which loops through each xml file in a folder.
The name of each xml file is put in variable.
The format of the filename is something like "part1_part2_part3.xml"
I need to store the 3 parts in three different columns of table A
The content of the xml file needs to be manipulated ("." needs to be replaced with ",", ....)and put in serveral columns in tableB
It's not clear to me yet how to start this but my main concern is read the three parts of the filename. I don't find any task in SSIS which could help me with that.
Could someone give me some pointers?
Many thanks!

Hi,
My Issue is that, I have to create a package which should read from multiple table from a RDBMS Source.
Right now I have different Source adapters for each table. I want to reduce the number of source adapters.
Can I
1) Create a connection manager and set the connection string from a variable. Set the variable from a script task. Put both of these into for loop container (no of tables).
Issues
a) Most of the table has same schema, but few have different, so all tables which has same schema will work.
For different schema anyway I have to create different data source.
b) Will Destination column mapping work.
If any one has already worked on it let me know.
Thanks

The problem that I am having is that I am not getting the results from an entire table, just a small subset. The sql command is "Select * from login", which has always implied to me, get everything, to end of table, or, until I tell you to stop. I am getting exactly, 10 items as input, and then it stops. I am including the code below in the hopes that someone can spot what it is that I am doing wrong.
The purpose of the routine is to convert a user login database into a new, expanded format.
TIA, Tom

In a stored procedure, I am trying to create a table and then read it from within that SP or from another one (nestsed). When I run the below code (simplified version of my real SP), no records are returned even though I know that there is data. The table is created and records are inserted, I just cannot read the records from the SP or one that calls it with an EXEC.
Any ideas? My code is listed below. (When I get this to work, I plan to convert the code to manipulate a temporaty table).
Alter Procedure spWod_rptWoStatusSummary_9
As
BEGIN
CREATE TABLE tblStatusSummary (TckStaffCd_F Char(3), RecType Char(20))
INSERT INTO tblStatusSummary
SELECT TckStaffCd_F, RecType
END
BEGIN
Select * from tblStatusSummary
end

Hello,
Any help here much appreciated.
I am using sql server 2000 to perform address cleansing. there is a point in my scripting when a table i pass values to becomes read/write.
i suspect this is when i run a cursor through the table.
Is anyone able to confirm for me whether running a cursor changes a table's properties?
Many thanks.
Tim
Ps as the table seems to be read/write it is harder to tell if NULLs are in the table and this is messing with joins I have further down the track.

I am quite new to MS SQL, and I want to read rows from a todo table, andwhen a row has been processed, I want to delete that row.Ages ago in MySQL I would probably have locked the table, select, processa row, delete a row, unlock the table.I have been reading through the documentation from MS SQL, but it's notclear what exactly I should do.Since I want to lock only one table in the select (the others just providedata, and are not modified), what's a good solution?--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

I have a data file that I converted from Access to SQL Server using theupsizing wizard. I then attached the tables to the Access front end using anODBC connection. I have one table that is read only for some reason. I'mnot sure how that happened, it went through the same procedures as the othertables in terms of upsizing and connecting. The original table was not readonly or hidden or anything else, it had full permissions.I've tried disconnecting and reconnecting the table but still the samething. In SQL Server, the permissions are the same as all the other tables.I can't seem to figure out what's making this one read only.I'm using SQL Server 2005 Express and Access 2003. Any ideas would begreatly appreciated.Thanks!

Hi,
We currently use an access database to manipulate data in tables on a SQL server. The end user copies a list of ProjNo from a spreadsheet into an Access table. The Access table is used as the criteria for 5 Access queries. It is common that one of the queries does not get run.
I figured I would create a Storied Procedure on the SQL server, call the storied procedure from MS Access using the MS Access table as the criteria to run the Storied Procedure. I do not know how to provide the Storied Procedure the ProjNo in the MS Access table. The number of ProjNo records in that table can vary.
I've found info on how to add one record at a time but I need a more of a batch process approach.
Can you point me in the right direction?
Thanks,
Mary

I have a requirement to read a value from table and increment it by 1. There can be multi-threads doing the same operation and would need a ROW LOCK so that read and write both are atomic. How can i put an exclusive lock on the row before I read the value from the table.
CREATE TABLE [dbo].[tblOnboardingSequence](
[OnboardingSequenceID] [uniqueidentifier] NOT NULL,
[Name] [nvarchar](255) NOT NULL,
[NextNumber] [bigint] NOT NULL,
CONSTRAINT [PK_OnboardingSequence] PRIMARY KEY CLUSTERED(
[OnboardingSequenceID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
My Stored Procedure has below logic
DECLARE @NextNumber BIGINT
----------- Acquire row lock here
SELECT @NextNumber = NextNumber FROM tblOnboardingSequence WHERE Name = 'TPO'
UPDATE tblOnboardingSequence SET NextNumber = @NextNumber + 1 WHERE Name = 'TPO'
----------- Release row lock here
I would like to have a row lock for the row having Name "TPO" before SELECT query and release after UPDATE query.
What si the best way to deal with this?
