如何在Oracle存儲過程中獲取逗號分隔值

我必須將FlightDate,FlightNumbers作爲參數傳遞給Oracle存儲過程，如下所示。如何在Oracle存儲過程中獲取逗號分隔值

CREATE OR REPLACE PROCEDURE GetPaxDetails(
    FlyingDate IN PAX_DETAILS.FlightDate%TYPE, 
    FlightNumbers IN VARCHAR(300)) 
IS 
BEGIN 
    -- Assume that we've received **FlightNumbers** as '0620,0712,0154' 
    -- Basically I am trying to select all passenger details (PAX_DETAILS) 
    -- for those flights passed in as a parameter(**FlightNumbers**) 
    -- for the specified dates 
    -- In this procedure the query should be generated something like below: 
    SELECT * 
     FROM PAX_DETAILS 
    WHERE TO_DATE(FlightDate,'DDMONYY') BETWEEN TO_DATE(FlyingDate,'DDMONYY') 
              AND TO_DATE(FlyingDate,'DDMONYY') + 1 
     AND FlightNo IN ('0620,0712,0154') 

END

我不理解如何FlightNumbers參數轉換爲類似AND FlightNo IN ('0620,0712,0154')查詢裏面。

你嘗試過：SELECT * FROM PAX_DETAILS WHERE TO_DATE（FlightDate， 'DDMONYY'）之間TO_DATE（FlyingDate， 'DDMONYY'）和TO_DATE（FlyingDate， 'DDMONYY'）+ 1和FlightNo IN（ FlightNumbers） – Satya

你嘗試過使用動態sql嗎？： http://stackoverflow.com/questions/5007725/pl-sql-using-a-dynamic-query-inside-a-stored-procedure – planben

你可能會發現你的答案她：[發送一個值的數組到Oracle過程在WHERE IN子句中使用]（http://stackoverflow.com/questions/13580245/sending-an-array-of-values-to-oracle-procedure-to-use-in-where-in-clause） –

作爲方法之一，該regexp_substr()和regexp_count()正則表達式函數可以用來分割源字符串到錶行，然後你可以很容易地包括導致您IN條款：

-- splitting a comma separated string 
select regexp_substr(FlightNumbers, '[^,]+', 1, level) as num 
    from dual 
connect by level <= regexp_count(FlightNumbers, '[^,]+')

所以，舉例來說，如果你在FlightNumbers爲「0620,0712,0154」通過，上述查詢將產生以下結果：

NUM 
-------- 
0620 
0712 
0154

有了這樣的手，最終竟被查詢d是：

with numbers(num) as(
    select regexp_substr(FlightNumbers, '[^,]+', 1, level) as num 
    from dual 
    connect by level <= regexp_count(FlightNumbers , '[^,]+') 
) 
SELECT *   -- do not forget INTO clause 
    FROM PAX_DETAILS 
WHERE TO_DATE(FlightDate,'DDMONYY') BETWEEN TO_DATE(FlyingDate,'DDMONYY') 
             AND TO_DATE(FlyingDate,'DDMONYY') + 1 
    AND FlightNo IN (select num 
         from numbers);

很好的使用'regexp_count（）'，11g中的new。 – APC

11g中的新功能 –
