Updating table while open cursor
But if you look closely, most of the time we use cursors to iterate through a row collection and update the same table.
In these type of situations it is ideal to use a Update Cursor, than using the default read only one.
Update Cursor("ANHIC_RANKING_FINAL", ["ANHIC_RANKING", "DESCRIPTION"]) as cursor: for row in cursor: row.
There can be a situation where you have to use a cursor, even though the experts say not to use cursors or to avoid them as much as possible.

A Cursor is always associated with a Select Query and it will process each row returned by the Select Query one by one.Then you need to declare the Cursor by giving it a name and setting its type as READ_ONLY and along with the FOR keyword you need to write the Select Query which will return the records you need to process.: It is very important to DEALLOCATE a Cursor as otherwise it will stay in database and when you declare a Cursor with same name again, SQL Server will throw an error: A cursor with the name ' Cursor1' already exists.The major disadvantage of a Cursor is its performance issue.A Cursor can be really slow when performing operations on large number of records and your SQL Query may take minutes to execute and produce results.
