Using OLE columns in a DataWindow object
You can create OLE columns in a DataWindow
object. An OLE column allows you to:
-
Store blob (binary large-object) data, such as Microsoft Excel
worksheets or Microsoft Word documents, in the database -
Retrieve blob data from a database into a DataWindow
object -
Use an OLE server application, such as Microsoft
Excel or Microsoft Word, to modify the data -
Store the modified data back in the database
You can modify the document in the server, then update the
data in the DataWindow object. When the database is updated, the
OLE column, which contains the modified document, is stored in the
database.
Database support for OLE columns
If your database supports a blob datatype, then you can implement
OLE columns in a DataWindow object. The name of the datatype that supports
blob data varies. For information on which datatypes your DBMS supports,
see your DBMS documentation.
