How to access data from Ms-Acess and oracle?
View 4 RepliesWe have an Oracle 11g R2(UNIX) server. A directory was created on this UNIX box for the purpose of uploading/downloading CSV files.I need to access this directory, programmatically from VB.Net in order to search for a specific file (a log file more precisely) and then open it it programmatically in Notepad from my Vb.Net application. I should also be able to delete or copy it to my local drive.I am trying to find a VB.Net code sample that would allow me to implement this: Read/Write/Open files on an UNIX directory.

I recently upgraded my system to Windows 7 64bit and ever since then I have had nothing but issues with my code attempting to access an Oracle database. I was using msdaora for my connection string however that does not work in 64bit. I changed over to OraOLEDB.Oracle which everything I can find on Google says to use however it fails every time. I have installed Oracle 11g 2 times now and even tried reinstalling VB.net 2010 and still no luck.
Here is my connection string....
Code:
MyConn.ConnectionString = "Provider=OraOLEDB.Oracle;Server=emsp.grhq.XXXX.com;Data Source=emsp;User Id=XXXX;password=XXXX"
And I am inporting....
Code:
Imports System.Data.OracleClient
Yet when I try it says...

Provider cannot be found. It may not be properly installed.
I am reading a csv file in to a datatable in vb.net and making a few checks and appending an extra column.

View 6 RepliesI have installed Visual Studio 2010 and Oracle 11g in my Window 7. Oracle seem to be fine because i can connect to System user, Create user and create database. But the problem is that I can not connect the Oracle to my VB.net project and there is no System.Data.OracleClient Namespace. Do I need to install Oracle Client in my computer even though i have installed Oracle Server?
View 2 RepliesIn my code I have an Oracle command that contains an INSERT statement. Here's a snippet from my SQL:
"'," & "To_Date('" & Format$(dtDateTime_Stamp, "MM/dd/yyyy hh:mm") & _
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've written several loading programs in the past, but never with VB.NET, always VB 6.0.I need to load a text file (actually, there are 24 per day), into our Oracle database. I have the file open and I can read it no problem, the question is, what's the best way to load it?
In the past, I've always read a record into an array and then passed the array as a variable into the Oracle statement in my code - basically loading one record at a time. I'm wondering if there's a better way to do this, specifically in the new world of VB.NET. Is there a way to load everything at once, rather than running an INSERT statement for every record individually?
