You've got the most important point correct. When you issue that commit in the middle of a cursor all locks on the data tables are released. To be technically correct the cursor is also invalid and with any other database management system you'd have to close and reopen the cursor. If you've included the "for update" clause in the cursor declaration then you will have to close and reopen the cursor no matter what. Oracle tries to be a nice rdbms by allowing us issue a commit across a cursor, but beware of the ORA-01555 error that you've caused on yourself.

Are the following statements regarding cursors TRUE 1. If you issue a commit within a for cursor loop you release all locks regardless of whether you're cursor statement has a FOR UPDATE statement in it or there is a WHERE CURRENT statement within the loop. 2. If you are using OPEN CURSOR...FETCH INTO statements to get the data the same rule applies.
