多行SQL语句拼成一条数据

将多条数据组合到一行

  declare @sql varchar(5000) set @sql=‘select ‘‘roleinfo:‘‘‘
  declare @column varchar(20)

  declare cursor1 cursor for
  select id from Userrole where 登录名=‘tl‘

  open cursor1

  fetch next from cursor1 into @column

  while @@FETCH_STATUS=0
    begin
        set @sql=@sql+‘,‘+@column+‘as id,(select 角色 from UserRole as s where s.id=‘+@column+‘) as 角色名称‘
        fetch next from cursor1 into @column
    end

  close cursor1
  deallocate cursor1
  exec (@sql)
