Hi Developers, 

My Function return following error

"System.Data.OracleClient.OracleException: ORA-06550: line 1, column 7:" & vbLf & "PLS-00221: 'TESTING2' is not a procedure or is undefined". 

When I change it to do "Select testing() from dual" and change CommandType to Text, it works. What am I missing?

Dim oracleConn As OracleConnection = CreateConnection(<connection info here>)
    Dim oracleCmd As New OracleCommand()
    oracleCmd.Connection = oracleConn
    'oracleCmd.CommandText = "SELECT TESTING2() FROM DUAL" 'this works
    oracleCmd.CommandText = "TESTING2"   'this does not work
    oracleCmd.CommandType = CommandType.StoredProcedure
    'oracleCmd.ExecuteReader()  'also tried this
    Dim tmpVar As String = oracleCmd.ExecuteScalar()
create or replace FUNCTION testing2
RETURN VARCHAR2
AS      
begin
  return 'hello';
end;

Any help would be amazing thank you!

    Re: Call Oracle Function From .NET As Stored Procedure

    Hi Ezra,


    You can try as following 

    replace your line of code from the following line of code 

    Dim oracleConn As OracleConnection = CreateConnection(<connection info here>)
    Dim oracleCmd As New OracleCommand()
    oracleCmd.Connection = oracleConn
    oracleCmd.CommandText = "TESTING2"   
    oracleCmd.CommandType = CommandType.StoredProcedure
    Dim prm = new OracleParameter("returnvalue", OracleType.VarChar)
    prm.Size = 1024
    prm.Direction = ParameterDirection.ReturnValue
    oracleCmd.Parameters.Add(prm)
    oracleCmd.ExecuteNonQuery()
    Console.WriteLine(prm.Value.ToString)

    I hope it resolve your problem.
