## Detailed Description

The ICommand interface defines behavior common to all commands in FDO. In order to be executed, commands must have an association to a connection. Commands can also be optionally associated with a transaction if the connection supports transactions. The parameter values collection allows values to be specified for commands that support expressions and/or filters.
