语法异常，如何也想不通_Sql Server

语法错误，怎么也想不通
declare cur cursor for... open cur
fetch next from cur into ...
while(@@FETCH_STATUS=0)
if（...)
begin
...
end
fetch next from cur into ...
end

至此没有错误，但是在if后面加一个else段就出错了

declare cur cursor for... open cur
fetch next from cur into ...
while(@@FETCH_STATUS=0)
if（...)
begin
...
end
else
begin
... --即使此处为空也报错
end
fetch next from cur into ...
end

消息 156，级别 15，状态 1，
关键字 'fetch' 附近有语法错误。
消息 102，级别 15，状态 1，
'end' 附近有语法错误。

while 后面加 begin

SQL code

--begin end 中必醃有語句塊（肯定報錯）declare cur cursor for... open curfetch next from cur into ...while(@@FETCH_STATUS=0)begin  if（...)  begin  ...  end  else  begin  ...  end  fetch next from cur into ...end

语法没什么问题，看下是不是有中文的空格

探讨

中文空格也检查了，现在的情况，把if段begin end内的代码去掉还是这个错误；如果只加else，不报错，else后面加begin end就出错。
郁闷啊~~~~

第一个if后面你用的是中文的括号

if @dptname='全部机构' 后面的Begin...end错了
