sql server - How to store record before it updated? -
i use sql server database. have 2 tables inspections
, history_inspections
.
before record inspections
table updated, need store history_inspections
table.
i wanted use sql server update trigger fired after record updated.
any idea how can store record inspections
table in history_inspections
table before updated ?
when after update
trigger in sql server fires, inserted
pseudo table inside trigger contains new values (after update
), , deleted
pseudo table contains old values (before update
).
so in case, read out rows deleted
table , store history_inspections
table.
create trigger trg_afterupdateinspections on dbo.inspections after update insert dbo.history_inspections(list of columns) select (list of columns) deleted
