Length Property

HRESULT GetLength(LPLONG pRetVal);

備註
For SQL Distributed Management Objects (SQL-DMO) objects referencing columns and user-defined data types defined on character data types, such as char and nchar, interpret the Length property as a number of characters. For objects referencing columns and user-defined data types defined on binary data types, such as varbinary, interpret the Length property as a number of bytes.
