I have a table with a blob field that stores photos in jpg format. Is there any way to direct fill the Dataset with the OracleDataAdapter?
Like:My code in vb.net
Dim oAdp As OracleDataAdapter Dim v_oDs As DsSubRegistro <- My Dataset
oAdp = New OracleDataAdapter(myConnection.sqlCmd("SELECT * FROM ..."))
With oAdp.TableMappings.Add(Common.DbDataAdapter.DefaultSourceTableName, v_oDs.Foto.TableName).ColumnMappings
I`m using oleDbConnection in order to Select a BLOB data from Oracle column, and I have to stick with this type of connection since all my application is using it.
After I used the following code, I got the error: unspecified [code]....
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:
I'm trying to get VB6 to access an Oracle (9i) procedure and return a dataset without much success.Not used VB6 that much but I need to do it for this application as we are not able to install the .Net framework on this particular server.Oracle procedure has an input param and an OUT param which is defined as a sys_refcursur
CREATE OR REPLACE PROCEDURE "LOGMNR"."LM" (p_filename in varchar2, p_recordset OUT SYS_REFCURSOR)[code].....
I get the same error message regardless of wetheror or not the second output parameter is enabled.3709 The connection cannot be used to perform this operation. It is either closed or invalid in this context.how to return a recordset from Oracle to VB6?
Hoping for some advice, probably an easy question for most people on here but I'm a mere learner. Basically, what would generally be the reason for using a Data Set via adapter rather than just connecting to the database directly using an SQL connection?
I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System
I'm making an app where people need to log in, these data are on a Oracle 10g XE DB, I know how to access the data, but I don't know how to validate is the query returns something or doesn't (to validate the username and password, of course). I'm using an ODBC with VB.net to connect the DB.
i am trying to copy data from a standard Dataset to a Type Dataset (XSD) of same table structure. i want to use Automapper to do that one. So how can i do that using automapper?
I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all. [Code]
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.
can you tell me,how can i add a provider for oracle(Microsoft Provider oledb for oracle).Actually i had Microsoft ODBC for oracle but i want to add a provider above mention.
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: ID DISP_ID1 52 83 5 e.g. SQL Table name DispTbl
I developed an application with old VB form and binding the data from Oracle database into VB form. Actually, I tried to bind the data more than 35000 records in to grid. But, it takes more than half an hour and also form was hanged and there is no output. Can you please let me know the solution to fix it and bind the data without any hang in my application. What are the steps to be followed to fix it?
Is there a way to transfer huge amount of data in a single shot from vb.net to Oracle database? I have a couple of thousands of records in my vb.net code which I want to update to Oracle database. What I do currently is, call a stored procedure in database once for each of those records. This would end up calling the stored proc couple of thousand times, which is highly inefficient.
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:
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.
So I have an application that queries a database for something like a social security number. Originally, the connection was established programmatically using ODBC. Now, I want to use the data source option built into Visual Studio.
I have a VB.Net application that populates an Oracle 11g global temporary table. I can see data in the temporary table by loading it into a grid and everything looks correct.However, when I call an Oracle stored procedure from VB.Net that would manipulate the data in this temporary table, the stored procedure reports that my temporary table is empty.I understood that data in an Oracle global temporary table should be visible to all sessions.
I had a datagridview with databound. I want to write a coding is when user click at any cell of the datagridview, then it will get the whole data of the row and save it into oracle database.
Is this code correct to fill this table? If not, why? Honestly, I've found several perspectives on how to do this sort of thing, some of which are linked below:

I am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?
All of the columns populate correctly except for the Long column. It returns a null for all rows. I have tested the SQL statement in Toad and it works perfectly. how to get an Oracle Long data type to populate in a gridview? This is driving me nuts
