Updating record through cursor
Follow this pattern: SET NOCOUNT ON DECLARE @Vendor ID int, @Vendor Name nvarchar(50), @message varchar(80), @product nvarchar(50) PRINT '-------- Vendor Products Report --------' DECLARE cur Vendor CURSOR FOR SELECT Vendor ID, Name FROM Purchasing.Vendor WHERE Preferred Vendor Status = 1 ORDER BY Vendor ID OPEN cur Vendor FETCH NEXT FROM cur Vendor INTO @Vendor ID, @Vendor Name WHILE @@FETCH_STATUS = 0 BEGIN PRINT ' ' SELECT @message = '----- Products From Vendor: ' @Vendor Name PRINT @message -- DO PROCESSING HERE -- Get the next vendor.(However, loops automatically use a cursor internally to avoid memory problems.) A more interesting usage is to return a reference to a cursor that a function has created, allowing the caller to read the rows.This provides an efficient way to return large row sets from functions. As usual, this gives flexibility so the query plan can vary from one run to the next (see Section 39.10.2), and it also means that variable substitution is not done on the command string.As with is used to open a cursor variable whose query was bound to it when it was declared. A list of actual argument value expressions must appear if and only if the cursor was declared to take arguments. The query plan for a bound cursor is always considered cacheable; there is no equivalent of , as the cursor's scrolling behavior was already determined.

FETCH NEXT FROM cur Vendor INTO @Vendor ID, @Vendor Name END CLOSE cur Vendor DEALLOCATE cur Vendor Kalman Toth - Database, Data Warehouse & Business Intelligence Architect SQLUSA: The Best SQL Server 2005 Training in the World! ;-) Try the following: CREATE PROC sample SP AS Declare @id varchar(15) begin declare tbl_loop cursor for select id from test SP open tbl_loop fetch tbl_loop into @id while (@@fetch_status = 0) begin update test SP set flg = 1 where id = @id insert into test SP2 values(newid(), @id) fetch next from tbl_loop into @id end end close tbl_loop deallocate tbl_loop Respectfully, Ralph D.
