Could you please explain, how to use Cursors ?

1. Declare a CURSOR
2. OPEN a CURSOR
3. FETCH data in CURSOR
4. finally close CURSOR

DECLARE @AccountID INT
DECLARE @getAccountID CURSOR
SET @getAccountID = CURSOR FOR
SELECT Account_IDFROM AccountsOPEN @getAccountIDFETCH NEXTFROM @getAccountID INTO @AccountIDWHILE @@FETCH_STATUS = 0BEGIN
PRINT @AccountIDFETCH NEXTFROM @getAccountID INTO @AccountIDEND
