从SubQuery创建表格

Question

这是我的密码：

create table sw_tmp6_gar_crm as
SELECT * FROM(
  select as_fid_x_gara.dat_fine_perio        as dat_fine_perio,
         as_fid_x_gara.cod_soc               as cod_soc, 
         as_fid_x_gara.cod_kto_gar           as cod_kto_gar, 
         as_fid_x_gara.cod_fido              as cod_fido,
         fid.dat_delib             as dat_delib, 
         fid.dat_scad              as dat_scad  

  from   it_soc_x_fv,
         as_fid_x_gara   ,
         rt_fidi         
  where  it_soc_x_fv.flg_tp_soc     in ('C','N')
    and  as_fid_x_gara.dat_fine_perio   = 2008-03-06
    and  as_fid_x_gara.cod_soc          = it_soc_x_fv.cod_soc
    and  rt_fidi.dat_fine_perio   = as_fid_x_gara.dat_fine_perio
    and  rt_fidi.cod_soc          = as_fid_x_gara.cod_soc       
    and  rt_fidi.cod_fido_tecnico = as_fid_x_gara.cod_fido 
     )         
;

我收到以下错误：

编译语句时出错:失败: parseexception行10:9无法从源识别“it_soc_x_fv”、“as_fid_x_gara”附近的输入

你能帮我吗？

Answer 1

您需要为子查询指定一个alias名称。下面这个应该能用。

create table sw_tmp6_gar_crm as
SELECT * FROM(
  select as_fid_x_gara.dat_fine_perio        as dat_fine_perio,
         as_fid_x_gara.cod_soc               as cod_soc, 
         as_fid_x_gara.cod_kto_gar           as cod_kto_gar, 
         as_fid_x_gara.cod_fido              as cod_fido,
         fid.dat_delib             as dat_delib, 
         fid.dat_scad              as dat_scad  

  from   it_soc_x_fv,
         as_fid_x_gara   ,
         rt_fidi         
  where  it_soc_x_fv.flg_tp_soc     in ('C','N')
    and  as_fid_x_gara.dat_fine_perio   = 2008-03-06
    and  as_fid_x_gara.cod_soc          = it_soc_x_fv.cod_soc
    and  rt_fidi.dat_fine_perio   = as_fid_x_gara.dat_fine_perio
    and  rt_fidi.cod_soc          = as_fid_x_gara.cod_soc       
    and  rt_fidi.cod_fido_tecnico = as_fid_x_gara.cod_fido 
     ) tmp         
;

但是正如注释中提到的，您不需要子查询。

Answer 2

你没有正确地把这些表化成一个别名。在from语句中，您没有提到表的任何别名，在select列中，您说的是fid.dat_delib，fid.dat_scad。

但是您的查询中没有fid表或别名。

如前所述，不需要子查询，您可以直接编写一个查询而不需要子查询。
