Data Access :: Return String From Oracle Anonymous Block
Oct 30, 2015
I am trying to execute oracle procedure (anonymous block) with input and output parameters from ms sql code and return 2 values back:a number and a string.I am using **EXEC() AT** to execute oracle code and return a string back to ms sql. It works fine when returning numbers, but if I add a string output parameter, I am receiving an error:Msg 0, Level 11, State 0, Line 0...A severe error occurred on the current command. The results, if any, should be discarded.
The server log has the following entry in exception.txt:
Exception 0xc0000005 EXCEPTION_ACCESS_VIOLATION reading address 00000005031C07E0 at 0x0000000070F9C183
There is also a SQLDump file generated:
* BEGIN STACK DUMP:
* 10/28/15 12:45:38 spid 63
* Exception Address = 000000005040C183 Module(MSVCR100+000000000003C183)
[code]....
It looks like the problem is in passing varchar2 from oracle into ms sql. I had logging code in oracle block, and it works fine. I have found a few examples of using **exec() at** but there is always only integer output passed back.
Hi, Is there anyway I can impliment this in my application without installing it as a COM. My Web Hoster says they won't install it. The Data Access Application Block
I download the DAAB CF version. However, most of them use SQLCEClient to connect to the database. Is there any DAAB that use SQLClient? One workaround that I made is I replaced all SQLCEClient objects with the SQLClient objects. I only test one method "ExecuteDataset" and it works so far. However, my question is "does my workaround a good solution?"
We have an application that requires write settings to reportserver virtual directory for the IUSR account when anonymous is turned on during the install. Once the install is complete, we lock down the IUSR account so that it only has browse access to the virtual directory when enabling anonymous access.
We automate the uninstall and install of our daily builds and I'm trying to figure out if I can automated this process somehow either through command line utility or in vbs.
I'm trying to use the Data Access Application block, and am having some issues with configuration. I am using it in a class library, and it seems that with v 3 you need to configure the DAAB first, making changes to the configuration file. However, in a class library, I do not seem to have the web.config or app.config file to change. So where do I need to store the configuration settings? Thanks, Paul
We are expanding an application's database hardware to have a mirrored failover server. Normally in this case we just have the application add "Failover Partner=MirredServerName" in the connection string.
However, this application is using the Enterprise Library Data Access Block and we can't find any documentation describing how to setup the Failover Partner using this library. Any help would be appreciated.
we recently got a scenario that we need to get the data from oracle tables which is installed on third party servers. we have sqlserver installed on ourservers. so they have created a DBLINK in oracle server to our sqlserver and published the DBLINK name.
what are the next steps that i need to follow on my sqlserver in order to access the oracle tables ?
This is my code... public partial class test : System.Web.UI.Page {protected void Page_Load(object sender, EventArgs e) {SqlDatabase database = (SqlDatabase)DatabaseFactory.CreateDatabase("ConnectionString");DbCommand command = database.GetSqlStringCommand("SELECT UserName FROM Users WHERE UserID = '6264'"); using (IDataReader reader = database.ExecuteReader(command)) {if (reader.Read()) {lblTest.Text = "test"; } } } }
This is my error: Server Error in '/' Application.

Any help with this matter would be very much appreciated. Thank you for your time. Sincerely, Jeffrey Pham
I have a set of reports that should be accessible to any user on our network. Those reports are located in a single folder in SSRS. I would like to configure security to allow anyone to see the reports in that folder. Is there a way to do this?
I do have other folders where I am using security so I do not want to open up system-wide access to all reports.
I'm attempting to move data from an Oracle table to an Access table using an Oracle stored procedure in DTS. The problem is that you can't pass parameters to an Oracle stored proc when its called in a data pump task. Is there a way to pass global variables into an Oracle stored procedure which retrieves data and moves it to an Access database? Maybe in an Active X task? We are required to use an Oracle stored procedure by our DBA's or else I'd just pass the variables into a SQL string and use it in the data pump task.
I have a requirement to set up an Oracle linked server, Ive never done this before and in fact never touched Oracle so I dont really know what I am doing.
Can I create ODP.NET connection in my SSIS connection manager. I had downloaded and installed ODP.NET on my server provided by oracle. The idea is I need to test this provider and see what is the difference connecting oracle database and the data load speed.
I need to run a script in production that adds primary key to a table. Because table is large, I can't run it in one shot, the log file is not so large to accommodate it. Instead, I created a new table with same structure plus new surrogate primary key, and I populate it in a cursor loop.
I already ran it many times in test server, and no problems with that. But the problem will be in production when applications will be accessing this table and try to insert/update it while I am running my loop.
So I am looking for a solution how to block users to access this table, it's OK if they receive an error. Setting database to single user mode will not work because I don't want to block them from all the rest tables in this database.
I have the following stored procedure to test scope of variables
alter proc updatePrereq @pcntr int, @pmax int as begin
[Code] ....
In the above script @i is declare in the if block only when the @pcntr value is 1. Assume the above stored procedure is called 5 times from this script
declare @z int set @z = 1 declare @max int set @max = 5 while @z <= @max begin exec dbo.updatePrereq @z, @max set @z = @z + 1 end go
As i said earlier `@i` variable exists only when `@pcntr` is `1`. Therefore when i call the stored procedure for the second time and so forth the control cannot enter the if block therefore @i variable wouldn't even exist. But the script prints the value in `@i` in each iteration, How comes this is possible should it throw an error saying `@i` variable does not exist when `@pcntr` values is greater than `1`?
I currently have the following connection string set up in Excel to connect to my SQL db:
Provider=SQLOLEDB.1;Persist Security Info=True;User ID=XXXXXX;Initial Catalog=YYYYY;Data Source=SQL;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=PROJMNT1;Use Encryption for Data=False;Tag with column collation when possible=False
What I would like to do is replace the Workstation ID (which apparently is hard coded?) so that the user's workstation name pulls (%COMPUTERNAME%) so that I can see who is connecting, using what, for how long etc etc.
I am using C# in Visual Studio 2008 and remote database as sql server 2008 R2. I want to read remote database table's field value and i have to move that read value to string variable. how to do it.
And my code is :
string sql = "Select fldinput from tmessage_temp where fldTo=IDENT_CURRENT('tmessage_temp')"; SqlCommand exesql = new SqlCommand(sql, cn); exesql.CommandType = CommandType.Text; SqlDataReader rd1 = default(SqlDataReader); rd1 = exesql.ExecuteReader();
create a new Connection Manager by right-clicking in the Connection Managers section of the design area of the screen. Select New OLE DB Connection to bring up the Configure OLE DB Connection Manager dialog box. Click New to open the Connection Manager. In the Provider drop-down list, choose the Microsoft Jet 4.0 OLE DB Provider and click OK. Browse to the Access database file and connection set up---all good!!!
Dataflow task Add an OLE DB Source component Double-click the icon to open the OLE DB Source Editor. Set the OLE DB Connection Manager property to the Connection Manager that I created . Select Table from the Data Access Mode drop-down list. I cannot see the tables set up as set up as pass-through table types to a Oracle 9i db
I have a quick question regarding getting data from a SQL database but I am slightly confused as to the best way to handle it.
Basically on of the projects I am working on I need to send data to another company, there are several calls required to the database to bring back various options for changing the questions asked on the front end.
Up to now all that has happened is there has been a mutual agreement between myself and this other company and they have just had access to the database to call a series of stored procs which I have written for them to access the data. Recently however the situation has changed and my client wants me stop them accessing the database however they still need to recieve the information from the database they recieve now.
What will be the best way to handle this? My knowledge of SQL is farily limited presently and I am only ust getting into learning a lot more about it.
I have an Oracle 9i server. To access the data in Oracle, I setup an ODBC connection to it and am able to return data from it using WinSQL (a general ODBC database client). The SQL statement is simply "SELECT * FROM COLOR" and all 133 records returned properly.
I need to copy the data from the Oracle server to SQL Express, therefore I set up linked server (by Microsoft ODBC provider) using the same ODBC connection as described above.
The problem is: only 32 records returned.
May I ask if there is any problem to this linked server setup?
Is there a clean way to block access to a peer which has been offline, during peer-to-peer transaction recovery (while the outstanding transactions are being applied)?
The code block is embedded into a grid view item template. <ItemTemplate> <% if ((bool)Eval("isNew")) { %> New Post <% } %></ItemTemplate> but as per rule Eval and Bind can be only use bind the data. How would i pull the information from sqldatasource in the template like this?
I am using sqljdbc41.jar to connect with MSSQL database, it is working fine on my local machine.Where as on the remote server, same class giving me error
Login failed for user '<domain><windows loginID>' My connection string is URL...
I am using sqljdbc41.jar and on 64 bit processor , I am using following command which included path for sqljdbc_auth.dll java -Djava.library.path= C: sqljdbc_4.1enuauthx64 TestDao and error is Login failed for user '<domain><windows loginID>' why it is not picking up username passed in connection string. I have 2 machines, one is local and other is remote. on both machine I login using my domain, it is working absolutely fine on local then why the error is coming on remote machine.Both the machines are identical.
