ループで参照カーソルを書き込む

Question

参照カーソルをループに書き込むことはできますか？出来ますか？そうでなければ提案をする？

FOR bd_id_rec IN (SELECT BD_ID FROM DEAL D WHERE D.BD_NR=BD_NR_REC.BD_NR AND BD_VERSION_NR IN (SELECT MAX(BD_VERSION_NR) FROM DEAL D WHERE D.BD_NR=BD_NR_REC.BD_NR AND QUOTE_DIST_CD='A')) 
LOOp 
open v_refcursor for(SELECT D.BD_NR,D.BD_ID, D.BD_VERSION_NR, L.PROD_GNRC_NR_TX, L.PROD_OPT_CD, LD.AUTH_BD_NET_PRC_AM, D.W_L_STAT_CD, L.LINE_NR FROM DEAL D, LINE_ITEM L, LINE_DISC_SCALE LD, EU_CUST E 
WHERE 
D.BD_ID=bd_id_rec.bd_id 
AND D.CONTROL_CNTRY_CD=l_control_cntry_cd 
AND D.BUS_MODEL_CD=l_bus_model_cd 
AND D.MC_CHARGE=l_mc_charge 
AND D.QUOTE_DIST_CD=l_quote_dist_cd 
AND D.QUOTE_DIST_DT_GMT>SYSDATE-60 
AND LD.SCALE_ID IN (SELECT MAX(SCALE_ID) FROM LINE_DISC_SCALE WHERE bd_id=d.bd_id) 
AND LD.BD_ID=D.BD_ID 
AND LD.LINE_NR=L.LINE_NR 
AND E.DFT_ENDCUST_OTRPRTYSITE_INSTID=l_dft_otrprtysite 
AND E.DFT_ENDCUST_OTRPRTYSITE_ID=l_dft_endcust_otrprt_id 
AND L.PROD_GNRC_NR_TX=prod_rec.PROD_GNRC_NR_TX 
AND L.LINE_TYPE_CD='PN' 
AND L.BD_ID=D.BD_ID 
AND D.EU_CUST_NR=l_eu_cust_nr) 
LOOP 
end loop; 

可能かどうかサンプルコードも与えてください。 Refカーソルをループ内でどのように使うことができますか？

Answer 1

もちろん、反復スルーカーソルにはネストループを使用できます。例えば。

-- iterate through first cursor 
FOR rec_cursor1 IN (SELECT column1, column2 FROM my_table1) LOOP 
    -- iterate through second cursor 
    FOR rec_cursor2 IN (SELECT * FROM my_table2 t2 WHERE t2.column1 = rec_cursor1.column2) LOOP 
     -- some actions or another nested loop 
    END LOOP;   
END LOOP;
