I am inserting data in Database, that time I got this severe. so please help me
There is a unique constraint in the table you try to update.
Try to remove the key field from your insert statement. It may be a number field, which the database will generate automatically on insert.
Hope it helps.
I think your inserting duplicate data, can you remove the unique constraint in Data Base otherwise check the unique constraint field and try to update that field.
Thanks for giving your thoughts.
I found that ERROR. we have a primery key in Database. so same data again we will inserting that time it will appear.
