來自匿名列 mssql 的條件

Question

告訴我如何應用別名“order_status”的條件，發誓錯誤的列名，我想完成 order_status like '% Prodact%' 的條件

   select oh.id_order_head,
           oh.order_name,
           oh.order_name,
           oh.date_recept,
           subj.subject_name,
           cdir.ul_name,
           (select dbo.func_common_get_state_list (oh.id_order_head, 15)) order_status
    from order_head oh
    join
        access_subject subj on oh.id_manager = subj.id_access_subject
    join
        common_ul_directory cdir on oh.id_customer = cdir.id_common_ul_directory

Answer 1

您需要將此查詢嵌套在一個塊中，如下所示或使用內聯查詢

例如：

with data
as(
        select oh.id_order_head,
               oh.order_name,
               oh.order_name,
               oh.date_recept,
               subj.subject_name,
               cdir.ul_name,
               (select dbo.func_common_get_state_list (oh.id_order_head, 15)) order_status
        from order_head oh
        join
            access_subject subj on oh.id_manager = subj.id_access_subject
        join
            common_ul_directory cdir on oh.id_customer = cdir.id_common_ul_directory
)
select *
  from data
 where order_status like '%Prodact%'
