Property Value

CommandType

One of the CommandType values. The default is Text.

Implements

CommandType

Exceptions

ArgumentException

The value was not a valid CommandType.

Remarks

When the CommandType property is set to StoredProcedure, you should set the CommandText property to the full ODBC call syntax. The command then executes this stored procedure when you call one of the Execute methods (for example, ExecuteReader or ExecuteNonQuery).

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

The .NET Framework Data Provider for ODBC does not support passing named parameters to an SQL statement or to a stored procedure called by an OdbcCommand. In either of these cases, use the question mark (?) placeholder. For example:

SELECT * FROM Customers WHERE CustomerID = ?

The order in which OdbcParameter objects are added to the OdbcParameterCollection must directly correspond to the position of the question mark placeholder for the parameter.

Note

The .NET Framework Data Provider for ODBC does not support the CommandType setting of TableDirect.
