Suddenly INSERT, UPDATE and DELETE fails for a certain file (a table in a remote system which I believe is an AS/400).
The linked server that we make use of is set up in SQL Server, and it's using an ODBC data source (DSN). The Data source is an "ODBC-data source for iSeries Access for Windows".
Only one single table has this problem. We can make inserts and updates in other tables using the same linked server, without any errors, and SELECTs still work for the problematic table.
We get these messages for INSERT and UPDATE statements (server and DB names replaced in the code below):
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "MYSERVER" reported an error.
The provider did not give any information about the error.
Msg 7343, Level 16, State 2, Line 1
The OLE DB provider "MSDASQL" for linked server "MYSERVER" could not INSERT INTO
table "[MYSERVER].[MYDB].[DMPCOM].[DMPXIF]". Unknown provider error.
And DELETE gives this message:
The OLE DB provider "MSDASQL" for linked server "MYSERVER" could not delete from
table ""MYDB"."DMPCOM"."DMPXIF"". There was a recoverable, provider-specific
error, such as an RPC failure.
If you have any clues to this, please don't hesitate to answer this question.
Thanks,
Andreas
The reason to the error was that journalling had been turned off on the AS400 file, that we connect to from SQL Server using linked server and an ODBC iSeries datasource. This had also turned commitment control off.
Setting commit to "Commit immediate (*NONE)" on the ODBC iSeries datasource did however not help. (Perhaps there is more to it than changing that setting.)
The database administrator of the AS/400 system recreated the table with its default settings, including journaling and commitment control, and then it was all back to normal, and insert, update and delete worked, from the linked server connection.

I have been working on SQL Server 2017 via R (on Rstudio as well as R on SSMS) and i am unable to connect to a specific database. I mention the database name in the connection prompt but, it gets connected only to the master database. Is there something that I am missing while connecting?
The syntax I use for connection is:
conn = "Driver={ODBC Driver 13 for SQL Server};server=;Uid=uid; pwd=pwd;Database = mydb"
I am trying to use both RevoscaleR as well as ODBC() package in Rstudio to connect to a specific database but, it still gets connected to master database. Using RStudio connections pane, if i try to explore the other databases, it shows only dbo schemas and no other schemas even if they exist. Can someone help me in figuring out what might have gone wrong?
Most likely the login you use (the uid) is not authorized for that particular database (it is not created as a user in that database).
Some example code you can run in SSMS as - for example - sa:
--switch over to the database in question
USE mydb
GO
CREATE USER uid FOR LOGIN uid;
The above code creates a user in the database in question with the same name as the login.
Hope this helps!
How to create a small and simple database using Oracle 11 g and SQL Developer ?
I am seeing too many errors and I cannot find any way to make a simple database.
For example
create database company;
Caused the following error:
Error starting at line 1 in command:
create database company
Error at Command Line:1 Column:0
Error report:
SQL Error: ORA-01501: CREATE DATABASE failed
ORA-01100: database already mounted
01501. 00000 - "CREATE DATABASE failed"
*Cause: An error occurred during create database
*Action: See accompanying errors.
EDIT-
This is completely different from MySQL and MS-SQL that I am familiar with.
Not as intuitive as I was expecting.
First off, what Oracle calls a "database" is generally different than what most other database products call a "database". A "database" in MySQL or SQL Server is much closer to what Oracle calls a "schema" which is the set of objects owned by a particular user. In Oracle, you would generally only have one database per server (a large server might have a handful of databases on it) where each database has many different schemas. If you are using the express edition of Oracle, you are only allowed to have 1 database per server. If you are connected to Oracle via SQL Developer, that indicates that you already have the Oracle database created.
Assuming that you really want to create a schema, not a database (using Oracle terminology), you would create the user
CREATE USER company
IDENTIFIED BY <<password>>
DEFAULT TABLESPACE <<tablespace to use for objects by default>>
TEMPORARY TABLESPACE <<temporary tablespace to use>>
You would then assign the user whatever privileges you wanted
GRANT CREATE SESSION TO company;
GRANT CREATE TABLE TO company;
GRANT CREATE VIEW TO company;
...
Once that is done, you can connect to the (existing) database as COMPANY and create objects in the COMPANY schema.
Actually the answer from Justin above could not be more incorrect. SQL Server and MySQL are for smallish databases. Oracle is for large enterprise databases, thus the difference in it's structure. And it is common to have more than one Oracle database on a server provided that the server is robust enough to handle the load. If you received the error posted above then you obviously are trying to create a new Oracle database and if you are doing that then you probably already understand the structure of an Oracle database. The likely scenario is that you attempted to create a database using dbca, it initially failed, but the binaries were created. You then adjusted your initial parameters and re-tried creating the database using dbca. However, the utility sees the binaries and folder structure for the database that you are creating so it thinks that the database already exists but is not mounted. Dropping the database and removing the binaries and folders as well as any other cleanup of the initial attempt should be done first, then try again.
From your question description, I think you were to create a database schema, not a database instance. In Oracle terminology, a database instance is a set of files in the file system. It's more like data files in MySQL. Whereas database in MySQL is somewhat equivalent to Oracle's schema.
To create a schema in Oracle: https://docs.oracle.com/cd/B19306_01/server.102/b14200/statements_6014.htm
To create a database instance in Oracle (I personally prefer CDBA):
https://docs.oracle.com/cd/E11882_01/server.112/e25494/create.htm#ADMIN11068
Notice the Oracle Express edition does not support mounting more than one database instance at one time.
I have a ASP.NET web application which does some changes on a table in SQL Server 2008 R2.
On this table there is a trigger that does updates on another table in another database on the same database server.
When saving the changes I'm having the following error:
- The error message: The underlying provider failed on Commit.
- InnerException: This SqlTransaction has completed; it is no longer usable.
Also allowing the database user to connect to the other database isn't working.
Somebody knows how I can make this work?
The trigger is not related to Entity Framework.
The trigger fires when changes are made to the table irrespective of where that change came from.
This is probably a rights issue, the system is attempting to make the change to the second database with the security context that was used to connect to the first database. It the change that was caused by the trigger fails, then everything in the same transaction will fail.
Since you are accessing 2 databases in a transaction, you are using MSDTC, make sure that it is started and that you have rights to it.
I am trying to set up the SQL Adapter in BizTalk 2009 to use a Stored Procedure in our SQL 2008 DB. For some reason, when I click "generate" in the wizard, and then click "next," I receive the following message:
Failed to execute SQL Statement. Please ensure that the supplied syntax is correct. New Transaction cannot enlist in the specified transaction coordinator.
I know the stored proc works, because we call it from C# code as well and I don't have a problem with it. I'm pretty sure I'm missing something basic, but I can't find what it is, and the only information I can find on using Stored Procs through the BizTalk SQL Adapter only show Select statements, so I don't know if there's some other setting I"m missing.
Here's the Stored Proc:
SET NOCOUNT ON;
Declare #Client int
set #Client = (Select Client_Id from Clients where Client_Name = #clientName)
Insert Into [FTP_Data].[dbo].[FileLog](Client_Id, Client_Name, FileType, Received)
Values(#Client, #clientName, #fileType, GETDATE());
Edit/Update: When I move the solution off my developer box and onto the actual server box, it works fine. As far as I can tell, the only difference is that the actual BizTalk Server components (instead of just the developer stuff) are on the same machine as the SQL Server to which I'm connecting. I would think that should be an issue, though...
"New Transaction cannot enlist in the specified transaction coordinator". Seems to indicate a possible DTC error. Is this the SQL server that the BizTalk databases are installed on?
In normal condition, I can add schemas in the dbml file to empty database with code below.
But now when I run this code, I take the error "Cannot drop database "test" because it is currently in use." How can I do it?
Dim db As New UI_Class.UIData
If db.DatabaseExists Then
db.DeleteDatabase()
End If
db.CreateDatabase()
It might happen as your SQL Server Management Studio (SSMS) must be holding it.
Most likely something is connected to the db.
Common causes are:
Some other tool connected
Trying to delete the database you connected to.
Another user connected to the db.
