.net - Insert Large Blobs Into Oracle 10G Using System.Data.OracleClient?
Mar 26, 2010
Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.
I have a web site that I developed on Vista using Vb.net9. It makes a connection to Oracle. for the connection I use System.Data.OracleClient. It works fine on my machine, and our test server, but it does not work on the production server. We installed the Oracle Client 11 on the server. The error is System.Data.OracleClient requires Oracle client software version 8.1.7
We've tried, making a console app that opens the connection, connection runs fine, opens, displays a message and all is well there.Then we make a simple web form, put it in the directory of the program, just a button, opens the connection, try..catch, grabs error, same error.The console app was running under an Administrator, web site running under iwam. Is it possible that iwam has a different path?
I am using VS 2008 with frame work 2.0. On my development machine I am using Oracle 9 as database. When I deploy my application where Oracle 9 is installed it works properly. but it gives error on oracle8 NT installed machine as follow.
"System.Data.OracleClient requires Oracle client software version 8.1.7 or greater "I can get rid from this error.
i was under the impression that using the System.Data.OracleClient namespace will allow me to deploy my application without having the client machine install any OracleClient software besides the .Net Framework 2.0 which if i'm not mistaken, contains the System.Data.OracleClient.dll.
but after creating a WinForm application and then publishing it thru ClickOnce , i found myself getting this error when running the application on the client machine. is this a normal behavior or did i do something wrong in the process?
I have a windows service written in .NET 2.0 that will run every 5 minutes and executes bunch oracle SQL/PLSQL scripts based on time/validation, it throws the above said error some times against some SQLs, the same SQLs run fine at later point without any error, I have no idea what is going on with the app. I am not sure if this has any thing to do with oracle connection pool as I am properly closing the connections after every SQL execution.
Exception:
System.Exception: Unexpected return code: 1 at System.Data.OracleClient.DBObjectPool.GetObject(Object owningObject, Boolean& isInTransaction) at System.Data.OracleClient.OracleConnectionPoolManager.GetPooledConnection(String encryptedConnectionString,
I can't seem to get it to recognize System.Data.OracleClient. I downloaded and installed the 11gR2, added a reference to Oracle.DataAccess. Looks like there is a 4.112.1.2 and a 2.112.1.2 versions. I'm tried adding both to the project, but neither are giving me access to that assembly. i.e.
Trying to write a list of oracle commands to XML but keep getting this error. "There was an error reflecting type 'System.Data.OracleClient.OracleCommand'."

I am constructing a search function in a class to be used by several of our asp pages. The idea is simple, take a search term from the user and query the database for the item. Currently I am doing this the wrong way, which is vulnerable to SQL injection attacks (and ELMAH is in there to save the day if something goes wrong):
[Code]...
The problem is since I am using a like statement, I need to be able to have % on either side of the search word, and I can't seem to do that with '%:searchterm%', it just gives an error of ORA-01036: illegal variable name/number.Can I parameterize but still have my flexible like statement be a part of it?
I am reading a csv file in to a datatable in vb.net and making a few checks and appending an extra column. I then want to perform a bulk insert using microsofts Oracle.DataAccess (no choice in this) to an Oracle database. what would be the best way to perform this as there is no bulkImport like in SQLserver.
I have developed a windows application which connects to Oracle Database and upload and retrieve data (using System.Data.OracleClient). It is working fine in my developement system. When I build a setup and deploy in another system, it is giving error that Oracle Client is missing.
Do I have to install Oracle Client in the client system to run my application? (When I visit Oracle site for Oracle Client, it is asking me to download a 200 MB file)
Is there any other way to do this with out installing Oracle Client in the client system?
Greetings, I have installed Oracle 10g Express Edition database on a server and install the client on my PC. Now, I`m developing a vb.net application using visual studio 2005 and I need to use the oracle 10g express edition database. SO I initialize the connection using the following connection string:
Relatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.
I'm new to VB.net. I need to modify an existing application that connects to an Oracle db.How can i insert a value generated by an oracle sequence from vb? I have the following code so far:[code]But i receive an error because i have another field, ROWSTAMP, which is generated by a sequence?
Private Sub btnRegister_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegister.Click Dim msg As String = "" Dim result1 As Integer conKk.Close()
I am trying to insert date and time in dtime column in oracle database by using this code but it gives me following error ORA-01830 date formate pictures ends before converting entire output.
The value of strDateTime_Stamp is #1/19/2011 9:42:22 AM# I'm getting an error ( "ORA-01830: date format picture ends before converting entire input string") because I don't know how to correctly assign the AM/PM tag on the end -- you'll notice it just says "MM/dd/yyyy hh:mm" in my code. I've tried a bunch of different things but nothing works. I also find it odd that if I change the "MM/dd/yyyy hh:mm" to "mm/dd/yyyy hh:mm" (little m for month) it gives me a 42 for the month value, not a 1. The capital M's fix that but I'm curious to know why.how to I get it to show the AMPM on the end?
I have the following insert into statement. What I want to do is insert the values to gprdsql.TblOracleNos if TxtOracleNo is not empty, therefore if a user logs on and fill the textbox the values are saved to the table. However, if the oracle number exists in gprdsql.TblOracleNos (i.e, the values ) it should not insert the values, presently it creates the same record again with same values (when the save button is clicked) and this creates duplication. Instead probably bring a pop up message "Oracle number already exists. [Code]
If you are working on a large record in database. How you manage to use the INSERT,,UPDATE? I mean when selecting a record base on two tables or more and those tables consist of 20 columns it hazard to put all those columns in one query.
[code]...
How to lessen the code without typing all those queries over and over again ?
I have a suite of programs that currently store PDF files as BLOBs in a SQL Server database table. The purpose of this design is to take advantage of Adobe's PDF iFilter and Microsoft's Full-Text Search functionality to allow other modules of my suite to run queries against the contents of a PDF file.This has been a huge headache, however, resulting in databases that are gigantic and unwieldy. We have also run into problems getting the Adobe PDF iFilter to play nice at times. Further, re-creating the entire full-text index on an 80 GB database can take a looooooong time (when it works at all!).So, the new idea is to use the open source XPdf library to extract a copy of the textual contents from each PDF file, and instead of storing the entire BLOB, merely store that textual data for the full-text functionality. Then, instead of storing the whole PDF file in the database, it will be stored somewhere on the server's file system.My issue relates to that last bit, storing the file on the server's file system, and the subsequent serving of that file out to remote users. Currently, with the entire BLOB residing inside of SQL, it has been very simple (though not easy) to manipulate the BLOB from the server to the client and vice versa. Sending the files across the network in chunks worked out well, too. I'm not sure how to do what I want to do now, though. I'm thinking that it's not a good solution to simply make a network share where all of the PDF files are stored and let the remote user view them by issuing a: Process.Start("{remote file share}filename.pdf")What I would LIKE to do is the following:
1. A Search is run, and the end user selects a file for viewing. 2. The SQL Server knows where the file resides on the local file system. 3. Something (on the server) issues a command to create a temp copy of the file at a safe location that is shared over the network. 4. The client's program then opens the file using a web browser.
Advantages:
1. The main body of the PDF files are protected and hidden from the prying eyes of those who shouldn't see them. 2. PDF files with Fast Web View enabled will load in a linear fashion, improving user experience.
Drawbacks:
1. I don't know what the "something" is in #3 above. 2. I don't know what happens when a file type other than ".pdf" is the target of the URL in a web browser. I know simple image formats will just open, but what if the file is ".doc/x". What about any other file type? Is it the same as issuing a "Process.Start("") to the UNC path?
I have written a VB.NET program to open a word document and generate a .TIF file by printing it using the MODI printer. Usually the documents print fine. But, sometimes it appears as though all of the letters on each line are printed on top of each other which produces little square "blobs".[code]
I'm downloading a bunch of files from a URI but when they get big, I get an utOfMemoryException. I thought at first it was MemoryStream error but I'm pretty sure now that the error is rooted in the declaration of an array of Bytes that's too large. (Half a gig is fine, 1.7 gig is not.)
(Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang .) in this code. Could anybody tell me, why I have System.outofmemory exception when i release arrays? There is no exception while large arrays exist so why after their realesing??
i am trying to add a mpg file to resources. at the time of compiling it throws following exception.the size of file is 200mb. [code]how is it possible to add a large size file to exe resources?
We are in the final stages of releasing a new in-house written system within our company. We have opted to create a single system/project containing multiple programs (like a mini ERP system).We are stuck on the navigation mechanism which will allow the user to load the appropriate forms. I am personally not a fan of the Tree View control because I think it is unfriendly to users. I have been looking on the web for some inspiration and I am interested in the design of the OPEN BRAVO ERP system. Before we dive in though, I wanted to get other programmers opinions. What do you find works best in VB 2008?
