Oracle query in C# returns invalid Characters

Hello,

I am trying to create a simple Oracle application that queries some data
from Oracle. The problem is that it randomly returns trailing \0s instead of
the characters of a string.

Instead of:
NIC, returns sometimes as N\0\0
188524C-01, returns somtimes as 18852\0\0\0\0\0

Notice that length of the strings are the same, just some characters in the
end was replaced with \0s

this is my code:

\\\\\\\

this.DWConnecti on.Open();

OracleCommand oraCMD = new OracleCommand(" Select * from table_v where (wname
= 'F18104854')" , this.DWConnecti on);

OracleDataReade r myResultsReader = oraCMD.ExecuteR eader();
while(myResults Reader.Read())
{
myResultsReader .GetValues(valu es);
}

this.DWConnecti on.Close();

Some Notes:
*It returns the correct number of records
*The problem seems to appear on String columns only
*The same column contains good and bad values
*Data Adapter causes the same problem
*Viewing data using the Query Builder tool, and Server Explorer works
*View data using the adapter at development time does NOT work

It may be something very silly I am missing...

Thanks,

I scoured the groups for some hands on code to perform the menial task of exporting table data from an Access 2000 database to Oracle database (in this case, it was oracle 8i but i'm assuming this will work for 9i and even 10g ) No one had what I needed, so I wrote it myself. I Rule. This code isn't going for efficiency, and isn't trying to be dynamic. It doesn't create the table structure in Oracle, that's up to you. (I

Ok, before I headbutt the computer... don't know why when I add criteria in a query, I get an 'invalid procedure call'. I also don't know why after searching the help in access, the various access newsgroups, the access support centre, I can seem to find no similar situation. I am not using any references, or VBA at all in the first place. I am trying to set up a simple (or so I thought) query to work with the text of two tables. ...

I am using Microsoft Access 2000 and Oracle 9.2.0.5 on Windows 2000. When I export a table from Access to Oracle using ODBC I get error: ORA 972 identifier too long I think the error is because one or more columns in Access table are longer than 30 characters. My question is how one can overcome this problem. I also see several column names which have /, ? or spaces in name

Hi, I am using an Access 2000 front-end to an Oracle 9 backend. I want to write a query that returns all records that are not older than one year for Column "Status_30" (which is a Date). When I look at the ODBC Datasource in Table DWHADMIN_V_PROBLEM , the Date formatting looks normal to me, like #05/07/2005#. However, when I try using the following in my Access Query :

HOWTO Run multiple SQL statements from ASP/ADO to an Oracle 10g. Please help, I'm trying to write an ASP page to use ADO to run a long query against an Oracle 10g database, to create tables, if they do not already exist.
