Using OLE columns in a DataWindow object
Contents
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.
