Oracle Cascade Delete Performance at Zachary Candace blog

Oracle Cascade Delete Performance. In manual bulk deletes starting with the children i expect a better performance than falling back to the cascade option. Is cascade delete on a table more efficient than individual delete statements (executed in a single plsql block) ? Depending on how you define reference constraints in your database schema, you might need to control whether a cascade deletion. On grandchild, there is an extra nonclustered index on (childid, + two other columns) as well as. I am interested in tuning the performance of: Delete from parentobject where parentobjectid = %d; 3) i would intuitively suppose that cascading delete using on delete cascade clause to be faster than deleting records from child. The delete statement attempts to delete one record. The tables are linked by foreign keys and every foreign key constraint has a delete cascade set on it. My deletes in oracle 11 are very slow.
