Remarks

When you set the CommandType property to StoredProcedure, you should set the CommandText property to the name of the stored procedure. The command executes this stored procedure when you call one of the Execute methods.

The Connection, CommandType and CommandText properties cannot be set if the current connection is performing an execute or fetch operation.

The OLE DB .NET Provider does not support named parameters for passing parameters to an SQL statement or a stored procedure called by an OleDbCommand when CommandType is set to Text. In this case, the question mark (?) placeholder must be used. For example:

SELECT * FROM Customers WHERE CustomerID = ?

Therefore, the order in which OleDbParameter objects are added to the OleDbParameterCollection must directly correspond to the position of the question mark placeholder for the parameter. For more information, see Configuring Parameters and Parameter Data Types.
