Wow, this is a great article, packed chock-full of everything you need to know about T-SQL cursors. A must read!
Precautions:
SQL Cursors are not toys. Please do not leave your child newbie developer unattended with cursors. In case your code is choking under the extra overhead of a cursor, contact a professional T-SQL develeper immediately. If problems persist, discontinue use of the cursor. Store cursors in a cool dry place. Do not deliberately inhale SQL cursors.
Important:
Before using a cursor, talk to your doctor developer about whether cursors may be right for you.
