How to use ExecuteReader() with Oracle DB?

hi,

In my appication i'm using Oracle as a back end. In that when i'm using ExecuteReader() it shows an exception. Can any one of help me to solve this issue.

<br />
oleDBConnection = new OleDbConnection(connectString);                   <br />
                    string query = "SELECT V_FIRST_NAME,V_LAST_NAME,V_PHONE_NUMBER,V_EMAIL,V_FAX_NUMBER,V_ADDRESS,V_TITLE,V_POSTAL_CODE,V_COUNTRY from UserDetails where (V_USER_ID = ?) AND (V_PASSWORD = ?)";<br />
<br />
                    OleDbCommand oledbCmd = new OleDbCommand(query, oleDBConnection);<br />
                    oledbCmd.CommandText = query;<br />
<br />
                    oledbCmd.CommandType = CommandType.Text;<br />
<br />
                    OleDbParameter par = oledbCmd.Parameters.Add("UserName", OleDbType.VarWChar, 50);<br />
                    OleDbParameter parm = oledbCmd.Parameters.Add("password", OleDbType.VarWChar, 50);<br />
<br />
                    oledbCmd.Parameters["UserName"].Value = userName;<br />
                    oledbCmd.Parameters["password"].Value = password;<br />
<br />
                    oledbCmd.Connection = oleDBConnection;<br />
<br />
                    oleDBConnection.Open();<br />
                    <br />
                    OleDbDataReader dr ;<br />
                    dr = oledbCmd.ExecuteReader();<br />

It threw an exception when executing the last line. The exception states that Unspecified error.Oracle error occured,but error message could not retrieved from Oracle.Data Type is not supported.

Thanks in advance

You add parameters to the query, but you don't specify anywhere these parameters. Try this

 string query = "SELECT V_FIRST_NAME,V_LAST_NAME,V_PHONE_NUMBER,V_EMAIL,V_FAX_NUMBER,V_ADDRESS,V_TITLE,V_POSTAL_CODE,V_COUNTRY from UserDetails where (V_USER_ID = @UserName) AND (V_PASSWORD = @password)";

OleDbCommand oledbCmd = new OleDbCommand(query, oleDBConnection);
oledbCmd.CommandText = query;

oledbCmd.CommandType = CommandType.Text;

OleDbParameter par = oledbCmd.Parameters.Add("@UserName", OleDbType.VarWChar, 50);
OleDbParameter parm = oledbCmd.Parameters.Add("@password", OleDbType.VarWChar, 50);

Hope it helps.

Ok, my bad. But still, you have to find a way to specify the parameters in the query. I think that that's your problem.

Odds are high that you're asking for help in using a webservice that most of us probably have not heard of. Otherwise, your question makes no sense at all. What do their docs say ? Do they have a support forum ?
