sql server 存储使用游标读取数据，按行判断

create proc wcProc

as

declare @wc nvarchar(30),

              @rgid nvarchar(30),

             @cur cursor,
    @job nvarchar(30),

set @cur = CURSOR LOCAL STATIC FOR --设置静态游标

    select  job,wc,rgid from WC where right(wc,5) <> RIGHT(rgid,5)
OPEN @curs 
while(1=1)
begin
  fetch next from @cur into @job,@wc,@rgid--按行读取数据
   if(@@fetch_status <> 0)--0为读取到数据
begin
 break
end

update jrtresource_mst set rgid=( N'GR' + RIGHT(LTRIM( RTRIM( @wc) ) ,5 ) ) where job=@job
end
close @cur--关闭游标
deallocate @cur--释放游标
