Question

我需要在表格中放置一些复杂的选择和结果。我试试这个：

INSERT INTO SAMGUPS_STATISTIC_STANTION
(SAMGUPS_STATISTIC_STANTION_SEQ.nextval)
(
with PRG as (
select
 ID_OBJ
from PEREGON where ID_STAN1=&arrival
),
STN_OBJ as (
          select
          distinct ID_OBJ_P as ID_OBJ
          from TMO start with ID_OBJ=&dispatch
          connect by prior ID_OBJ_P=ID_OBJ
),
STAN as (
          select
          A_TOP.ID_POEZD
          ,A_TOP.vrsvop
          from STN_OBJ inner join A_TOP on A_TOP.ID_OBJ=STN_OBJ.ID_OBJ and A_TOP.KODOP_P in ('01','07')
          left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
          WHERE ATR.NOM_POEZD LIKE '____'
),
DATA_RESULT as 
(
          select
          /*count(*) over() as TotalCount*/
          to_char(&dispatch) as dispatch
          ,to_char(&arrival) as arrival
          ...
          ,ATR.PR_N_V_PZ
          from PRG inner join A_TOP on A_TOP.ID_OBJ=PRG.ID_OBJ and  A_TOP.KODOP_P in ('03','07')
                    left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
                    inner join STAN STN on STN.ID_POEZD = ATR.ID_POEZD  
                    WHERE ATR.NOM_POEZD LIKE '____'
                    order by A_TOP.ID_POEZD
)
SELECT * FROM DATA_RESULT);

我有错误：

Error at Command Line:71 Column:25
Error report:
SQL Error: ORA-32034: unsupported use of WITH clause
32034. 00000 -  "unsupported use of WITH clause"
*Cause:    Inproper use of WITH clause because one of the following two reasons
           1. nesting of WITH clause within WITH clause not supported yet
           2. For a set query, WITH clause can't be specified for a branch.
           3. WITH clause can't sepecified within parentheses.
*Action:   correct query and retry

是否有规避这些限制？可能是选择放入变量然后使用变量插入表的结果吗？

Answer 1

WITH子句不能在括号内指定。

尝试像这样重写smth

INSERT INTO SAMGUPS_STATISTIC_STANTION
with PRG as (
select
 ID_OBJ
from PEREGON where ID_STAN1=&arrival
),
STN_OBJ as (
          select
          distinct ID_OBJ_P as ID_OBJ
          from TMO start with ID_OBJ=&dispatch
          connect by prior ID_OBJ_P=ID_OBJ
),
STAN as (
          select
          A_TOP.ID_POEZD
          ,A_TOP.vrsvop
          from STN_OBJ inner join A_TOP on A_TOP.ID_OBJ=STN_OBJ.ID_OBJ and A_TOP.KODOP_P in ('01','07')
          left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
          WHERE ATR.NOM_POEZD LIKE '____'
),
DATA_RESULT as 
(
          select
          /*count(*) over() as TotalCount*/
          to_char(&dispatch) as dispatch
          ,to_char(&arrival) as arrival
          ...
          ,ATR.PR_N_V_PZ
          from PRG inner join A_TOP on A_TOP.ID_OBJ=PRG.ID_OBJ and  A_TOP.KODOP_P in ('03','07')
                    left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
                    inner join STAN STN on STN.ID_POEZD = ATR.ID_POEZD  
                    WHERE ATR.NOM_POEZD LIKE '____'
                    order by A_TOP.ID_POEZD
)
SELECT SAMGUPS_STATISTIC_STANTION_SEQ.nextval,  DATA_RESULT.* FROM DATA_RESULT;

INSERT上不需要ORDER BY。
INSERT的编码如下：INSERT INTO mytable (mycolumn, ...) SELECT ...

尝试这样的事情：

INSERT INTO SAMGUPS_STATISTIC_STANTION
(dispatch, arrival, ..., PR_N_V_PZ)
          select
          to_char(&dispatch) as dispatch
          ,to_char(&arrival) as arrival
          ...
          ,ATR.PR_N_V_PZ
          from (select
                 ID_OBJ
                from PEREGON where ID_STAN1=&arrival
                )
          inner join A_TOP on A_TOP.ID_OBJ=PRG.ID_OBJ and  A_TOP.KODOP_P in ('03','07')
                    left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
                    inner join (select
                                A_TOP.ID_POEZD
                                ,A_TOP.vrsvop
                                from (select
                                      distinct ID_OBJ_P as ID_OBJ
                                      from TMO start with ID_OBJ=&dispatch
                                      connect by prior ID_OBJ_P=ID_OBJ
                                ) inner join A_TOP on A_TOP.ID_OBJ=STN_OBJ.ID_OBJ and A_TOP.KODOP_P in ('01','07')
                                left join A_POEZD_ATR ATR on ATR.ID_POEZD=A_TOP.ID_POEZD and ATR.VRSVOP=A_TOP.VRSVOP
                                WHERE ATR.NOM_POEZD LIKE '____') STN
                            on STN.ID_POEZD = ATR.ID_POEZD  
                    WHERE ATR.NOM_POEZD LIKE '____';

oracle插入和复杂选择。怎么了？
