The Assign( ) method and CURRENT-CHANGED function cannot check the current values against the initial values of BLOB or CLOB fields. By default, they raise an error if a row contains a BLOB or CLOB field.
The NoLOBs property specifies whether or not the AVM ignores BLOB or CLOB fields while executing the ProBindingSource's Assign( ) method or the CURRENT-CHANGED function. The default value of the NoLOBs property is FALSE.
