如何将列中的天数添加到DB2中的当前日期？

Question

I am writing this sql to dynamically calculate certain number of days as below. But I don't know how to make it work because I keep getting the error.

select Current Date + ( Dynamic numbr of days calculation here ) from  TableName

Usually all the guides shows examples as Current Date + 1 Day (this works but not the above) Any ideas how can I get it to work from ?

Answer 1

select Current Date + Dynamic numbr DAYS FROM TableName

eg

select Current Date + 15 DAYS  from TableName

here 15 is dynamic number.

Answer 2

SELECT CURRENT_DATE + (your dynamic numeric field) DAYS FROM FILE_NAME

Example based on AS400:

1)

SELECT CURDATE() + (FLDA) DAYS FROM FILEA

2)

SELECT CURDATE() + 8 DAYS FROM FILEA

Answer 3

Try this

 SELECT                                            
 DATE(DTE_BILL_EFFCTV - 301 DAYS)                  
 FROM BILL_ACCT                 
 WHERE                                             
 DTE_BILL_EFFCTV > DATE(CURRENT DATE - 300 DAYS) ;
