Oracle Cascade Delete Performance. The tables are linked by foreign keys and every foreign key constraint has a delete cascade set on it. We have some performance issue with cascade deletes. Delete 50000, comit, delete 50000, commit, repeat). Delete from parentobject where parentobjectid = %d; I am interested in tuning the performance of: We have a bunch of tables, around 40, which are children of 3 main tables. On grandchild, there is an extra nonclustered index on (childid,. Is cascade delete on a table more efficient than individual delete statements (executed in a single plsql block) ? The delete statement attempts to delete one. In manual bulk deletes starting with the children i expect a better performance than falling back to the cascade option. My deletes in oracle 11 are very slow. 3) i would intuitively suppose that cascading delete using on delete cascade clause to be faster than deleting records from. Currently we have to do this delete in batches of about 50,000 rows (ie.
