ExecuteReader: CommandText property has not been initialized

Trying to execute a stored procedure in Oracle and import the data into a dataset.

I keep getting ExecuteReader: CommandText property has not been initialized error.

I am not using a DataReader. Why is this poping up?

My code is as follows:

var odbcCommand = conn.CreateCommand();

OdbcParameter ODBCParameter1 = new OdbcParameter("@FROMDATE", OdbcType.VarChar, 30);

ODBCParameter1.Value = "01/28/2020";

OdbcParameter ODBCParameter2= new OdbcParameter("@TODATE", OdbcType.VarChar, 30);

ODBCParameter2.Value = "01/29/2020";

OdbcCommand ODBCCommand = new OdbcCommand("getReport", conn);

odbcCommand.CommandType = CommandType.StoredProcedure;

odbcCommand.Parameters.Add(ODBCParameter1);

odbcCommand.Parameters.Add(ODBCParameter2);

OdbcDataAdapter da = new OdbcDataAdapter(odbcCommand);

conn.Open();

DataSet ds = new DataSet();

da.Fill (ds);
