Answer / praveen singh
A cursor is a set of rows together with a pointer that
identifies a current row.
In other word, Cursor is a database object used by
applications to manipulate data in a set on a row-by-row
basis, its like recordset in the ASP and visual basic.
DECLARE @fName varchar(50), @lName varchar(50)
DECLARE cursorName CURSOR -- Declare cursor
LOCAL SCROLL STATIC
FOR
Select firstName, lastName FROM myTable
OPEN cursorName -- open the cursor
FETCH NEXT FROM cursorName
INTO @fName, @lName
PRINT @fName + ' ' + @lName -- print the name
WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM cursorName
INTO @fName, @lName
PRINT @fName + ' ' + @lName -- print the name
END
CLOSE cursorName -- close the cursor
DEALLOCATE cursorName -- Deallocate the cursor
