Question

I have uploaded an image and stored into image field in database, that image is stored as 0xFFD8FFE. When I am trying to update the above with null as getting an exception called:

The datatypes image and varbinary(max) are incompatible in the equal to operator

I want to change the above value to null.

Answer 1

Just set it to null with an update statement:

UPDATE dbo.MyTable
  SET MyFieldName = NULL
  WHERE MyPrimaryKey = 12345
