这可能是一个愚蠢的语法错误，但我只是继续阅读我的过程，但无法弄清楚我的错误在哪里。

消息156，级别15，状态1，第41行
关键字“ FOR”附近的语法错误。

这是我的代码：

alter procedure LockReservation as
DECLARE @edition_id tinyint, @stockid  tinyint;
DECLARE @creservation CURSOR FOR select edition_id from reservation where (date_fin - GETUTCDATE()) <= 12;
open creservation;
while @@fetch_status = 0
BEGIN
    fetch creservation into @edition_id;
    DECLARE @cstock CURSOR 
        FOR select id from stock where edition_id = @edition_id;
    open cstock;
    while @@fetch_status = 0
    BEGIN
        fetch cstock into @stockid;
        select stock_id from location where location.stock_id = @stockid and archivage = 0
        if @@rowcount = 0
        BEGIN
             insert into stocks_reserves(id, date_ajout, usure, suppression, edition_id) 
                    Select id, date_ajout, usure, suppression, edition_id 
                from stock 
                where stock.id = @stockid
        END
    END
    CLOSE cstock
    DEALLOCATE cstock
END
CLOSE creservation
DEALLOCATE creservation

有人可以帮我吗？
