Execute Oracle stored procedure from .NET

Question

I am trying to run this C# code

string sql = @"EXECUTE GETEMPLOYEES1()";

OracleCommand cmd = new OracleCommand(sql, cnn);
cmd.CommandType = CommandType.Text;

cmd.ExecuteNonQuery();

but I keep getting

Invalid SQL error

My stored procedure code is very simple

CREATE OR REPLACE PROCEDURE GETEMPLOYEES1 
AS 
BEGIN
    DBMS_OUTPUT.PUT_LINE('Welcome to FYICenter!'); 
END;  

I am able to run it normally by using CommandType = StoredProcedure but I need to execute some dynamic code entered by the user and it is vital to me to do it by CommandType = Text .

Answer 1

EXECUTE is a SQL*Plus command. Use either

CALL GETEMPLOYEES1()

or

BEGIN GETEMPLOYEES1(); END;

Also if you choose command type StoredProcedure the library adds BEGIN ... END; internally for you.

CALL also requires empty parentheses when a procedure is parameterless.

Answer 2

Try replacing DBMS_OUTPUT.PUT_LINE('Welcome to FYICenter!'); with null; , and see if that makes it any different. Im asuming in connection context there is no sense to try to output text, there is no console.
