Question

So I’m trying to call an Oracle stored procedure from my C# .NET application. Most online references I can find suggest “using System.Data.OracleClient;”, but .Net 3.5 doesn’t recognize that namespace so I’m using “Oracle.DataAccess.Client” instead.

Here’s some paraphrasing of my code below, with a previously setup and tested OracleConnection called ‘myConn’ already filled with parameter ‘:arg_myArg’ (it’s a number, if that matters):

command.Connection = myConn;
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "exec mySchema.myProc(:arg_myArg)"
command.ExecuteNonQuery();

The trick is that the procedure returns nothing by design, it simply populates a different table which I pull from. However, when I try to run the code above, I get a ‘OracleException’ on the final line and gives this error:

ORA-06550: line 1, column 13:
PLS-00103: Encountered the symbol "MYSCHEMA" when expecting one of the following:

   := . ( @ % ;
The symbol ":=" was substituted for "MYSCHEMA" to continue.

Removing the “exec” from the command gives this error instead:

ORA-06550: line 1, column 8:
PLS-00801: internal error [22503]
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored

Any ideas? I’d be happy to clarify anything

This is my first time posting on stackoverflow.com and my last week at this job, so I appreciate your understanding and relative haste with figuring this out

I think you need to something like this

command.Connection = myConn;
command.CommandType = CommandType.StoredProcedure;  
command.CommandText = "mySchema.myProc";  // the proc name   
command.Parameters.Add(/* TODO: Add parameter here */); 
command.ExecuteNonQuery();
