SELECT *

JOIN (select regexp_substr(P_NUM,'[^,]+', 1, level) as CAMPO1 from dual 
    connect by regexp_substr(P_NUM,'[^,]+', 1, level) is not null) D 
ON S.NUM = D.CAMPO1 

的想法是做一個「加入「與此結果，因爲」IN「是相當延遲... 謝謝，

Answer 2

使用dbms_lob版本instr和subst處理CLOB。請注意，與標準substr()相比，dbms_lob.substr()的第二個和第三個參數意義相反。未經測試！

... select dbms_lob.substr(P_NUM, dbms_lob.instr(',' || P_NUM || ',', ',', 1, level+1) 
           - dbms_lob.instr(',' || P_NUM || ',', ',', 1, level) - 1, 
          dbms_lob.instr(',' || P_NUM || ',', ',', 1, level)) as CAMPO1 
from dual 
    connect by dbms_lob.instr(',' || P_NUM || ',', ',', 1, level+1) > 0
