I have been developing my ASP.NET web pages to access the SQL database locally on my personal computer while using a "SqlConnection", but to access my SQL database on a host server, I must use a "OdbcConnection". I am mostly using LINQ to access data with a DataClassesDataContext, but sometimes I must use ADO with SqlConnection and SqlCommand. What must I do to convert my C# code in order to access data with ODBC 3.51?
View 2 RepliesI am working on an asp webform that pulls from an ODBC datasource then puts the data in an sql server. Once the data is in the sql server several queries pull data from it to provide information for a report.
This is an example of what I am talking about
private
void ODBCpdEmployeeAb()
{
DataTable dt =
new
DataTable();
[Code]....
The first part gets the data from the ODBC connection and the next part stores it in an sql server table. The problem is I have these methods in the page load event of the webform so everytime it loads it just puts the exact same data in the sql server table which would then provide incorrect information on the report.
Is there a way to append the most recent data from the ODBC table to the sql server ?
my webserver is in the DMZ. The Database in the intranet. For connection from webserver to database the following entry is made in the odbc connection "TCPIP BCAST=NO;HOST=Intranet.Firma.local,Intranet_Spiegel.Firma.local,Intranet_Arbiter.Firma.local;PORT=2639}"
how to get this options in the connection strings working, or how i must modify the entitiy framework connection string to use the odbc entry?
<add name="KA_Entities" connectionString="metadata=res://*/Models.KA_Model.csdl|res://*/Models.KA_Model.ssdl|res://*/Models.KA_Model.msl;provider=iAnywhere.Data.SQLAnywhere;provider connection string="UserID=user;Password=password;DataSourceName=Databasename""
providerName="System.Data.EntityClient" />
<add name="KAPortal" connectionString="UserID=user;Password=password;DataSourceName=Databasename" providerName="iAnywhere.Data.SQLAnywhere" />
I tried to use odbcfor the entity framework, but the Wizard always add the right .NET Provider and not the odbc

In my windows application, i am listing the System DSN's configured on the remote machine in a combobox. Once i select the DSN and click on Connect button, i should be able to connect to the remote database. I am trying to open the connection to the database using ODBC but am getting the below error.

I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?

I have a local database which is updated regularly. Now I need a good way to reflect the local database changes into the remote sql server. Both the server have same database structure.
All the above pocess should work automatically from the local database server because I need to update the remote one so that the website visitor can get the updated results in the morning.I need a detailed description/ procedure to accomplish the work.
I fear this has been beaten to death, but I'm still struggling with the problem of reading Excel files in my ASP.NET application that has recently been ported to Server 2008 and 64-bit.Many posts I find point to the existence of 64-bit Microsoft drivers here:here and here. My concern is the warnings I'm also reading about these not intended "As a replacement for the Jet OLEDB Provider in server-side applications" possibly for thread-safe reasons? This IS a server-side application and while Excel uploads aren't hundreds-of-times-a-day ocurrances, they will be done by customers.I know there are also commercial libraries available and while I'm opening to considering them I do worry about the 'revision chase' and not getting burned by them going belly-up (it has happened to us before).
View 2 RepliesActually used to use Sql server, for that I add parameters like this
com.Parameters.Add("Field1",SqlDbType.Nvarchar,50).value=TextBox1.Text.
that works fine. but while using MSaccess and the datatype for of some table is Memo than how could I use parameter for that i am using System.Data.Odbc. cos here it is easy to do SqlDbType.Nvarcha cos there is shows Nvarchar but not Memo
I'm thinking the problem here is with my SQL Syntax, but I'm not sure and need a fresh pair of eyes to check it out. This is the code I'm using to connect to and then insert into the DB:
OdbcConnection datConn = CreateDataConn();
datConn.Open();
OdbcCommand comm = new OdbcCommand();
comm.CommandText = "INSERT INTO userdata (key, secretkey, uid) VALUES ('" + token + "', '" + secret + "', '" + twitterid + "');";
comm.Connection = datConn;
comm.ExecuteNonQuery();
datConn.Close();
And here is the CreatDataConn() method:
private OdbcConnection CreateDataConn()
{
OdbcConnection dbConn = new OdbcConnection();
dbConn.ConnectionString = "Dsn=MySQL;database=twittertest;option=0;port=0;server=localhost;uid=root;pass=Red!4jedi";
return dbConn;
}
I created a DSN to the database, which is hosted on my machine. When I run the application I get this error:
ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.51-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'key, secretkey, uid) VALUES ('127090765-i3aZl71LPSVUCPZs9kHSYeBli0vWpbq0BaM1roYC' at line 1
But for the life of me I can't figure out what's wrong with my syntax...It's prolly something simple, but again, I need a pair of fresh eyes to look at this.
I would like to connect oracle via ODBC. I downloaded the dll and add as reference.

I have a problem that I can't figure out. I shall read an images from a column in a MySQL database. I use a simple aspx page and the codebehind file with the code below.
It is ok to read the image if I don't use any parameter value in the where clause, but if I use it, nothing is returned. I don't know if I have done anything wrong in the code. I have also tried to set a proper value on the parameter.value without success. So my conclusion is that the parameter sertup is wrong in my code.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("id"))
