सूची सभी महीनों Oracle SQL

Question

दोस्तों का उपयोग कर, वहाँ यह सब के अलावा अन्य महीनों सूची किसी भी बेहतर तरीका है:

select to_char(add_months(to_date('01/01/1000', 'DD/MM/RRRR'), ind.l-1), 'MONTH') as month_descr, 
     ind.l as month_ind 
    from dual descr, 
     (select l 
      from (select level l 
        from dual 
       connect by level <= 12 
       ) 
     ) ind 
order by 2; 

उत्तर:

SELECT to_char(add_months(SYSDATE, (LEVEL-1)),'MONTH') as months 
    FROM dual 
CONNECT BY LEVEL <= 1 

एक और प्रश्न नीचे देखें

इसके अलावा मैं पिछले वर्ष सहित पिछले दो वर्षों की सूची बनाना चाहता हूं। मैंने इस एसक्यूएल क्वेरी को लिखा था। अगर कुछ बेहतर है तो मुझे बताएं।

select extract(year from sysdate) - (level-1) as years 
    from dual 
connect by level <=3 
order by years 

Answer 1

यूप।

1:

SELECT * FROM WWV_FLOW_MONTHS_MONTH; 

2: (युपीडी :)

WITH MONTH_COUNTER AS (
    SELECT LEVEL-1 AS ID 
    FROM DUAL 
    CONNECT BY LEVEL <= 12 
) 
SELECT TO_CHAR(ADD_MONTHS(TO_DATE('01/01/1000', 'DD/MM/RRRR'), ID),'MONTH') FROM MONTH_COUNTER; 

Answer 2

नहीं बेहतर है, लेकिन सिर्फ एक बिट क्लीनर:

SQL> select to_char(date '2000-12-01' + numtoyminterval(level,'month'),'MONTH') as month 
    2  from dual 
    3 connect by level <= 12

DECEMBER 

12 rows selected. 

सादर, रोब।

Answer 3

select to_char(add_months(trunc(sysdate, 'yyyy'), level - 1), 'MONTH') months 
    from dual 
connect by level <= 12;
