Gets the OracleParameterCollection.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
When the CommandType property is set to StoredProcedure, the CommandText property should be set to the name of the stored procedure. The user may be required to use escape character syntax if the stored procedure name contains any special characters. The command executes this stored procedure when you call one of the Execute methods.
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 property), do not precede the named parameter with a colon (:). The .NET Framework Data Provider for Oracle supplies the colon automatically.
The following example creates an OracleCommand and displays its parameters. To accomplish this, the method is passed an OracleConnection, a query string that is an SQL SELECT statement, and an array of OracleParameter objects.
