"cursor" what is that

Can anyone tell me where i could learn about "cursors", what they're for and how to code it ?
Thanks a lot !Cursor is basically a loop through the data. Where you can stop and process each row in this loop separately. They are too slow and not recommended to use often.

Read more on declaration and use here:
