Updatable Cursors

I am trying to write updatable cursors in a stored procedure? Can I get
any help to write updatable cursors?

Any help would be appreciated very much.

Thanks for your help in advance.

Can you post some sample data along with table DDLs so that others can
better understand your requirements? Most likely you can use efficient
set-based logic & avoid cursors which are generally lousy, slow & resource
intensive.

As Anith, I discourage you from writing cursors. Cursors have their
place, but it is a feature which you should use rarely. The performance
of cursor compare to the corresponding set-based operation is often
magntitudes slower.

If you have a problem which actually is best addressed by a cursor, don't
bother using WHERE CURRENT OF. Make the cursor INSENSITIVE, and update
the rows through key values. I have *never* had any need for WHERE CURRENT
OF.

Attached is a simplified example (the...

Hello, I am doing some multithreading in an MDI app, and I can't seem to get the cursor to stay as an Hourglass. I call: Cursor.Current = cursors.wait at the beginning of my routing, and set it back to cursors.default when the thread ends (using a callback)

Does Me.Cursor.Current=Cursors.WaitCursor set the current property of Me.Cursor to Cursors.WaitCursor And Me.Cursor.Current=Cursors.Default set the Me.Current property to something (default) stored in Me.Cursor. Or is Cursors.Default some process wide cursor shape? What is a correct statement?
