Question

如何从union语句中插入值列表（使用Oracle）？我有以下，但它不起作用：

INSERT INTO PS_Z_EXS_EMP_TBL (EMPLID) VALUES (
SELECT ee.emplid
  FROM ps_employees ee
 WHERE     ee.empl_status IN ('A', 'L')
       AND ee.emplid NOT IN (SELECT vc.emplid
                               FROM ps_vc_plan_mem vc
                              WHERE vc.vc_plan_id in ('PNC-RS','PNC-SO','PNC-ESPP'))
       AND ee.emplid IN
              (SELECT srv.emplid
                 FROM ps_Z_ADD_EMP_SRVDT srv
                WHERE     srv.emplid = ee.emplid
                      AND srv.z_serv_dt_type = 'ESP'
                      AND service_dt <= (SELECT asofdate FROM psasofdate))
UNION select EMPLID from ps_vc_plan_mem 
where vc_plan_id in ('PNC-RS','PNC-SO','PNC-ESPP')
);

Answer 1

您不需要values。只需使用insert . . . select：

INSERT INTO PS_Z_EXS_EMP_TBL(EMPLID) 
    SELECT ee.emplid
    FROM ps_employees ee
    WHERE  ee.empl_status IN ('A', 'L') AND
           ee.emplid NOT IN (SELECT vc.emplid
                             FROM ps_vc_plan_mem vc
                             WHERE vc.vc_plan_id in ('PNC-RS','PNC-SO','PNC-ESPP')
                            ) AND
           ee.emplid IN (SELECT srv.emplid
                         FROM ps_Z_ADD_EMP_SRVDT srv
                         WHERE srv.emplid = ee.emplid AND
                               srv.z_serv_dt_type = 'ESP'AND
                               service_dt <= (SELECT asofdate FROM psasofdate)
                        )
    UNION
    select EMPLID
    from ps_vc_plan_mem
    where vc_plan_id in ('PNC-RS','PNC-SO','PNC-ESPP');

插入从其他表中选择的数据时，您不需要“值”。尝试以下查询：

    ;with ins (emplid) as(
    select ee.emplid
    from ps_employees ee inner join ps_Z_Add_EMP_SRVDT srv
    ON ee.emplid=srv.emplid and srv.z_serv_dt_type='ESP' and srv.service_dt <=(select asofdate from psasofdate)
    where ee.empl_status in ('A','L')
    and not exists (select 1 from ps_vc_plan_mem vc inner join ps_employees ee2
        on ee2.emplid=vc.emplid)
    union select emplid from ps_vc_plan_mem where vc_plan_id in ('PNC-RS','PNC-SO','PNC-ESPP')
)
insert into PS_Z_EXS_EMP_TBL (EMPLID)
select emplid from t

使用ORacle为UNION sql执行INSERT INTO
