You can update the LOB on the server only if you are in edit mode.
Follow these steps to view or edit LOB data:
The Column LOB Type Associations dialog box opens. Use this dialog box to specify the Windows file format of the data.
The File Extension Mapping dialog box opens.
For example, if the mapping value is bitmap, change the file extension from LOB to .bmp.
The Column LOB Type Associations dialog box opens.
The Column LOB Type Associations dialog box closes and the LOB opens in the designated application.
A message box indicates how many rows in the database will be affected by the operation.
The LOB locators column now contains icons that correspond to the application, such as for bitmaps.
