I have a table containing records for all Departments.
I want to override the rows of only a specific department (Say Dept-A) with new rows.
For ex if Dept-A has 5 Rows, and the New set has only 3 Rows, and I want only the 3 Rows to be inserted under Dept-A , rest of the 2 Rows should be deleted.
The Size of the Table is about a Million. Approximate size of the Dept rows will be 3000.And the table should be available all the times. Is it possible to use LOAD (with NO COPYPEND) or any other functionality is available? Please advise.
