Gets or sets a value indicating how the CommandText property is interpreted.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
When the property is set to StoredProcedure, you should set the CommandText property to the full Oracle call syntax. The command then executes this stored procedure when you call one of the Execute methods (for example, ExecuteReader or ExecuteNonQuery).
The .NET Framework Data Provider for Oracle does not support the question mark (?) placeholder for passing parameters to an SQL statement called by an OracleCommand of CommandType.Text. In this case, named parameters must be used. For example:
SELECT * FROM Customers WHERE CustomerID = :pCustomerID
When using named parameters in an SQL statement called by an OracleCommand of CommandType.Text, you must precede the parameter name with a colon (:). However, in a stored procedure, or when referring to a named parameter elsewhere in your code (for example, when adding OracleParameter objects to the Parameters property), do not precede the named parameter with a colon (:). The .NET Framework Data Provider for Oracle supplies the colon automatically.
