Master/Details tables with CASCADE delete giving "table mutating" error
Hi,
I have two tables in a master/details configuration (table 1 is "master", table 2 is "details").
The details has a FK contraint relation to the master with a CASCADE delete (so when the master is deleted, all associated details are deleted).
The master table has a column "last_updated_datetime" which is updated by a master table update trigger whenever most (excluding the last_updated_datetime column) columns are updated.
The details table has an update trigger which also updates the master table's last_updated_datetime column (whenever a detail row is changed).
The details table also has a delete trigger which also updated the master table's last_updated_datetime column (whenever a detail row is deleted).
The problem I have is: When the master record is deleted, which cascade deletes the details record(s), the delete trigger on the details table throws a "table is mutating" error.
I understand that the "mutating" error is "correct" because the master record is being deleted.
But is there some way I can get around this problem (for example, having the details table delete trigger not update the master table last_updated_datetime) when it's this cascade delete?
Thanks for your help!
