at design time the tag [Memo] appears where the data should have been and at run-time it is empty.

hi gargic,

make persitance fields to your table/query
- doubleclick on the table/query-component->fieldeditor pops up
- rightclick on fieldeditor
- add all fields
--
add an aditional field
- rightclick on fieldeditor
- New Field
- define as string with length, give a name and select it as calculated


in table/query-event oncalculate do
table1.FieldByName('TheNewFieldName').AsString := TBlobField(Table1.FieldByName('YourLongFieldName')).AsString;
