我是这些 oracle 动态查询的新手,我只是想构建一个动态查询,所以我可以根据它获取记录。
这是我的 PL/SQL 语句:
declare
sql_query varchar2(5000) := 'select FKOM_OFFICE_ID,FKBAM_BUDGET_ID ';
begin
for x in (select distinct PFS_SOURCE_ID,PFS_SOURCE_ENG from PBS_FC_SOURCE WHERE PFS_UPPER_SOURCE_ID!=0 ORDER BY PFS_SOURCE_ID ASC )
loop
sql_query := sql_query ||
' , nvl(sum(case when FKBAB_SOURCE_ID = '||x.PFS_SOURCE_ID||' then FKOD_AMOUNT ELSE 0 end),0) as source_'||x.PFS_SOURCE_ID;
dbms_output.put_line(sql_query);
end loop;
sql_query := sql_query || ' FROM FMS_K_OFFICEWISE_DTL
JOIN FMS_K_OFFICEWISE_MST ON FMS_K_OFFICEWISE_MST.FKOM_OFFICE_MST_ID=FMS_K_OFFICEWISE_DTL.FKOD_OFFICE_MST_ID
JOIN FMS_K_BUDGET_ALLOCATION_DTL ON FMS_K_BUDGET_ALLOCATION_DTL.FKBAD_BUDGET_ALLOC_DTL_ID=FMS_K_OFFICEWISE_DTL.FKOD_BUDGET_ALLOC_AD_ID
JOIN FMS_K_BUDGET_ALLOCATION_MST ON FMS_K_BUDGET_ALLOCATION_MST.FKBAM_BUDGET_ALLOC_ID=FMS_K_BUDGET_ALLOCATION_DTL.FKBAB_BUDGET_ALLOC_ID
JOIN PBS_FC_BUDGET ON PBS_FC_BUDGET.PFB_BUDGET_ID=FMS_K_BUDGET_ALLOCATION_MST.FKBAM_BUDGET_ID
WHERE PFB_LEVEL_ID=2 GROUP BY FKOM_OFFICE_ID,FKBAM_BUDGET_ID ';
dbms_output.put_line(sql_query);
end;
由于我希望查询看起来不错,如何从上述语句中获取记录?
