Hello,

Data of computed field is not storing in database . Is there any particular reason for making computed field so ?

What is the benefit of not storing value of computed field in database ? Can anyone explain it in detail ? Please give a complete explanation.

Hello

 [ By default, a computed field is not stored to the database, and is

computed on-the-fly. Adding the attribute ``store=True`` will store the

field's values in the database. The advantage of a stored field is that

searching on that field is done by the database itself. The disadvantage

is that it requires database updates when the field must be recomputed. ]

Hi Nikesh,

We use computed fields, if the value of field is computed using some logic and depends on other fields. For example: Total in Sale order is computed from sum of line subtotal

Computed field compute its value every time we access its value instead of reading from database.
