SQL 查询混淆

Question

展示：

• 户口号码。
• 顾客ID
• 以十万为单位的初始金额（四舍五入到小数点后两位）[将列标题更改为“INITIALAMTIN_LAKHS”]
• 金额类别（amt < 50000 显示为“低”，amt > 5000000 显示为“高”，否则为“中”）[将列标题更改为“AMOUNT_CATEGORY”]
• 开始日期
• 到期日（使用以月为单位的期限来计算）[将列标题更改为“MATURITY_DATE”]

2004 年之后开始的所有“活跃”（大写）FD 账户。

这是我到目前为止所写的

SELECT ACCOUNT_NO, CUST_ID, ROUND(INITIAL_AMT,2) AS INITIALAMTIN_LAKHS, 
CASE 
    WHEN INITIALAMTIN_LAKHS<50000 THEN 'low'
    WHEN INITIALAMTIN_LAKHS>5000000 THEN 'High'
    ELSE 'Medium'
END 'AMOUNT_CATEGORY',
START_DT, FROM BANK_FD_ACCOUNT;

无法进一步了解

表一：

BANK_FD_ACCOUNT
(
  ACCOUNT_NO, 
  CUST_ID, 
  START_DT, 
  FD_TERM_MNTH, 
  INITIAL_AMT, 
  ACC_STATUS 
)

Answer 1

希望INITIAL_AMT实际上是数量，而不是十万或百万或类似的东西，那么你需要将其更改为数十万：

SELECT
    ACCOUNT_NO, 
    CUST_ID, 
    ROUND(0.00001 * INITIAL_AMT,2) AS INITIALAMTIN_LAKHS, 
    case 
        when INITIAL_AMT<50000 then 'Low'
        when INITIAL_AMT>5000000 then 'High'
        else 'Medium'
    end as AMOUNT_CATEGORY,
    START_DT
from 
    BANK_FD_ACCOUNT
where
    ACC_STATUS = 'ACTIVE' and
    START_DT >= '20150101'

不知道什么到期日或如何使用以月为单位的期限来计算它。

Answer 2

有效查询的示例...

SELECT ACCOUNT_NO
     , CUST_ID
     , ROUND(INITIAL_AMT,2) INITIALAMTIN_LAKHS
     , CASE WHEN ROUND(INITIAL_AMT,2)  <   50000 THEN 'low'
            WHEN ROUND(INITIAL_AMT,2)  > 5000000 THEN 'High'
            ELSE 'Medium'
       END AMOUNT_CATEGORY
     , START_DT
  FROM BANK_FD_ACCOUNT;

Answer 3

SELECT account_no, 
   cust_id, 
   ROUND(initial_amt/100000,2) AS initialamtin_lakhs, 
   CASE 
        WHEN initial_amt < 50000 THEN 'Low' 
        WHEN initial_amt > 500000 THEN 'High' 
        ELSE 'Medium' 
   END as amount_category, 
   start_dt, 
   ADD_MONTHS(start_dt, fd_term_mnth) AS maturity_date 
   FROM bank_fd_account 
   WHERE UPPER(acc_status) = 'ACTIVE' AND TO_CHAR(start_dt,'YYYY') > 2004

Answer 4

alter session SET NLS_DATE_FORMAT='DD-Mon-YYYY HH24:MI:SS';  
select ACCOUNT_NO,CUST_ID,
CASE
WHEN ROUND(INITIAL_AMT*0.00001,2)>FLOOR(ROUND(INITIAL_AMT*0.00001,2)) THEN 
TO_CHAR (ROUND(INITIAL_AMT*0.00001,2),'0.99')    
ELSE TO_CHAR(ROUND(INITIAL_AMT*0.00001,2))   
END as INITIALAMTIN_LAKHS,   
CASE  
WHEN INITIAL_AMT<50000 THEN 'Low'  
WHEN INITIAL_AMT>500000 THEN 'High'  
ELSE 'Medium'  
END as AMOUNT_CATEGORY,  
START_DT,  
ADD_MONTHS(START_DT,FD_TERM_MNTH) as MATURITY_DATE  
from BANK_FD_ACCOUNT   
where UPPER(ACC_STATUS)='ACTIVE' and TO_NUMBER(TO_CHAR(START_DT,'yyyy'))>2004;

Answer 5

Select account_no,  
cust_id,   
CASE  
WHEN ROUND(INITIAL_AMT*0.00001,2)<1 THEN   
TO_CHAR (ROUND(INITIAL_AMT*0.00001,2),'0.99')      
ELSE TO_CHAR(ROUND(INITIAL_AMT*0.00001,2))     
END "INITIALAMTIN_LAKHS",   
case  
when initial_amt < 50000 then 'Low'  
when initial_amt > 5000000 then 'High'  
else 'Medium'  
end "AMOUNT_CATEGORY",  
To_char(start_dt, 'dd-Mon-YYYY HH24:MI:SS'),  
To_char(add_months(start_dt,fd_term_mnth),'dd-Mon-YYYY HH24:MI:SS') as MATURITY_DATE  
from bank_fd_account  
where acc_status='Active'   
and To_char(start_dt,'YYYY')>'2004';
