SQL server使用自定义函数以及游标

create function combstr(@name nvarchar(50))
returns nvarchar(300)
as
begin
declare @resultStr nvarchar(300)
declare @tempStr nvarchar(500)
declare @flag int
declare myCur cursor --定义游标
For(select landCode from land where sectCode=@name )
open myCur ?C-打开游标
fetch next from myCur into tempStr ?C将游标下移
set @flag=0
while @@fetch_status=0
begin
if @flag=0
begin
set @resultStr=@tempStr
end
else
begin
set @resultStr=@resultStr+','+@tempStr
end
set @flag=@flag+1
fetch next from myCur into @tempStr
end
close myCur
deallocate myCur
return @result
end
