Hi,

I am in some confusion that if we prepare the view with the two or more table. and we insert the row in the view can changes are
reflected in the base table.
and if insert the row in the view, which is prepared from only one table will changes are reflected in the base table.
Regards
namrata

You may or may not insert in a view with a join.
Most likely you can't, you have to create a trigger (an "instead of" trigger) on the view to insert what you want in the correct base tables.

Unless it's a "key-preserved" view.

Yes, this is why I said "Most likely you can't".
In addition, you can see what you can do for each column with the views %_UPDATABLE_COLUMNS.
