   DWORD    dwFlags);

Parameters

  • pCommandID
    [in] The DBID of the command to load.

  • DB_E_OBJECTOPEN
    A rowset was open on the command.

    A provider-specific error occurred.

  • E_INVALIDARG
    pCommandID was a null pointer, or dwFlags was not zero.

Comments

ICommandPersist::LoadCommand loads the persisted command definition into the current command object. Loading a persisted command definition does not change the command object's transaction scope and semantics nor does it change the session scope. Set property values and specified parameter information are not affected by loading a persisted command definition. ICommandPersist::LoadCommand fails if the current command object has any outstanding rowsets (DB_E_OBJECTOPEN).
