oracle 处理字段值‘1,2,3’对应的实际值的处理方法

参考SQL：
select 
    dbdkcplx, 
    (select to_char(wm_concat(name)) 
    from dict_dbdkcplx cplx where a.dbdkcplx = cplx.code or a.dbdkcplx like '%, ' || cplx.code || ', %' or a.dbdkcplx like '%, ' || cplx.code or a.dbdkcplx like cplx.code || ', %'
) dbdkcplx1
from gsjk2018.v_proj_particulars_dflx a;

自己用本地表测试：
select dbdkcplx, 
(select to_char(wm_concat(cplx.dictname)) from base_dict_entry cplx where
            (a.dbdkcplx = cplx.dictid or a.dbdkcplx like '%, ' || cplx.dictid || ', %' or a.dbdkcplx like '%, ' || cplx.dictid or a.dbdkcplx like cplx.dictid || ', %')
            and dicttypeid = 'FMS_GUARANTEED_LOANS_TYPES'
) dbdkcplx1
from (select '1, 2, 3' dbdkcplx from dual)a;      

根据1,2,3查出的实际对应的值

字典表数据如下：

 实际案例参考:

select
(
    select to_char(wm_concat(bde.dictname)) from base_dict_entry bde where
    (
           jsonpkg.getval(pci.contractsummary,'guranteeMethod') = to_char(bde.dictid) 
        or jsonpkg.getval(pci.contractsummary,'guranteeMethod') like '%, ' || bde.dictid || ', %' 
        or jsonpkg.getval(pci.contractsummary,'guranteeMethod') like '%, ' || bde.dictid 
        or jsonpkg.getval(pci.contractsummary,'guranteeMethod') like bde.dictid || ', %'
    )
    and dicttypeid = 'GURANTEE_METHOD'
)as guranteeMethod  
FROM
(
    select  * from v_proj_baseAndParticipant p WHERE  p.BUSSTYPE != '07' and p.PROJSTAGE > 3005
    and p.REGUARANT!=1 and p.CHILDBUSSTYPE!='SY_QYZ' and p.BUSSTYPE != '06'
)p
LEFT OUTER JOIN legal_pactset_info  lpi  on  p.PROJID = lpi.PROJID
LEFT OUTER JOIN proj_contract_info  pci  on  pci.contractid = lpi.contractid;      

end
