DB/Reporting :: Oracle Database Filtered Search?
May 14, 2009
Im writing a simple VB program that connects to an oracle DB which retreives and inserts data to a table I created.[code].....
I want to be able to search through a table I have created to store all the information.Rather than just searching for one variable which would be easy to do, I want to give the user the option to filter out the search from the form.So say the user hits "Find", they would be given access to 10 comboboxes, they would select the information they want to search for (They do not have to select every box) and then click "Do Find".Then the form would display all the results of the query in the form.

I have a stored procedure on an oracle database called : GET_HVE_PACKAGE_VERSIONS This basically calls versions of PLSQL packages as stores the versions into a table. I am having big problems trying to call this procedure. I have tried everything. I am currently able to create and update etc etc using the executeNonQuery method and I thought that I would be able to call a procedure them same way, obviously not
the whole project depends on me being able to call procedures against the database.

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...
Quote:
Provider cannot be found. It may not be properly installed.

I am trying to use the .net connector within my program. I have got add, delete and update working however cannot get search to work. What I would like the program to do is, you enter a value into a textbox and then press a button. The value in the textbox is searched and then the values in the database corresponding to that value are entered into the other text boxes. This is what I have so far:
Private Sub PrescriberSearch()
pre.SelectCommand = New MySqlCommand("SELECT Name FROM Prescriber WHERE Name =?Name like Name = ?Name")

Scenero: Users inputs the barcode numbers into a textbox, hits the search button and is returned the description of that barcode.
Database:
Two fields: Barcode - barcodes in this field
Description - Description revalant to that barcode
Form:
Consists: Textbox(Input) - txtBarcode
Button(Process) -btnClick
Listbox(Outut) - lstDetails
Code:
Dim con As New OleDb.OleDbConnection
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
[CODE]...
This is the code i got to connect to the database itself. Then i got this code for the search part
Code:
SQL = "SELECT Description FROM Table1 where Barcode = '" & txtBarcode.text & "'"
What i need to know is:
1) Is the code for the search right.
2) How to get it so the description for that barcode is displayed in a listbox.

My aim is to choose from radio button 1 if worker is smoking (yes or no) and radio button 2 if the worker is married (again yes or no). According to the selection, the list of workers matching with the selected criterias should be shown in the listbox1. Here is the code I wrote and I do not know how to complete or correct:

I will try and explain my problem as simply as I can
I have an Oracle database (external app) that contains a number of tables that I need to get data from, however I also have an SQL database that contains a number of tables that my app is using.
e.g. Oracle Table name PD_112
Structure:
CODE:
What I want to do is get all the data from the Oracle table to display in a list control however I want the values in the DISP_ID column of the Oracle table to be change to the corrosponding DESC values from the DispTbl e.g. 5 from the Oracle table would display Piping instead of 5.
I know how to do this if both the tables where in one database system e.g. Oracle or SQL, however I am not sure the best why to do this when the tables are in 2 different data sources.
Below is the code for doing this in the same datasource:
Code:
I am using VB.Net 2005, just for info

Currently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet
-around 2000 users
-users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.

I have a copy Oracle 11g which is now fully installed. Will it work with Visual Basic Express 2008 or just Visual Studio 2008 Professional? I have both Visual Basic Express 2008 and Visual Studio 2008 Professional. I really would like to know if it works with Visual Basic Express 2008.

I am trying to use RAP (rabid application development). So I have created a database with a datagridview to show all information and textboxes to modify the informations. So far so good.
The problem is created when I try to use the search facility on the datagridview. The search is working but the problem is that the textboxes are not following the search criteria . I can configure this manual but I would like to know which is the easier way to configure the textboxes to show the value of my search criteria.
I also want to know how when I finished with the search criteria and empty the search the text boxes to make the connections back as they were before.

I need to do a lookup in a DatagridView column. I would like something with the blazing speed of what recordset.seek used to provide. I am assuming that a similar function/method is available for use with the DVG. What else is there to use that is better than my present implementation.

I've been viewing the tutorial at [URL]...08-088541.html but I'm still having issues creating my connection to our Oracle database. Here's my code, which uses the same connection string as one of my VB6 programs (no password required for database--Oracle picks up windows name) :
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Create connection object
Dim OraDB As String = "Data Source=databaseneme;Persist Security Info=False"
Dim conn As New OracleConnection(OraDB)
conn.ConnectionString = OraDB
conn.Open()
Me.Show()
End Sub
I've been using .NET for all of 10 mins so the error may be painfully obvious!

I am creating a Reporting program in VB 2008. The first issue that I want to correct is in VB 2008 there is a Database Explorer. But whenever I try to create a new Data Connection in the Database Explorer it does not give me the option to connect to Oracle. How do I get my Oracle Database in the Database Explorer tab. All it gives my options for are Microsoft based database applications.
