Surely you would just use date arithmetic? The date you would get 10 months before 1-Nov is 1-Jan. select date('1-nov-07') - '10 months' ==> '1-jan-07' select date('29-dec-07') - '10 months' ==> '28-feb-07' select date('29-dec-08') - '10 months' ==> '29-feb-08' “I have a date x. and I wish to know the date 10 month befor this x i.e. e.d. if it is 1st nov 2007 then 10 months before would be 1st feb 2007.”

Surely you would just use date arithmetic? The date you would get 10 months before 1-Nov is 1-Jan.

select date(’1-nov-07′) - ‘10 months’ ==> ‘1-jan-07′
select date(’29-dec-07′) - ‘10 months’ ==> ‘28-feb-07′
select date(’29-dec-08′) - ‘10 months’ ==> ‘29-feb-08′

When using intervals in calculations Ingres assumes the following:Converts a date interval into a floating-point constant expressed in the unit of measurement specified by unit. The interval function assumes that there are 30.436875 days per month and 365.2425 days per year when using the mos, qtrs, and yrs specifications. Using a month interval for calculations subtracts the number of months from the month component of the date leaving the day to be the same unless the day of the month doesn't exist. Trying this with ANSI dates and intervals provides the same behaviour. I've discussed this with John and we think that we're limited by Ingres date/time behaviour but we'll think about it some more.

I will post it here too. It goes like this: I have a date x. and I wish to know the date 10 month befor this x i.e. e.d. if it is 1st nov 2007 then 10 months before would be 1st feb 2007. This is calculations are needed for some calculations. here various options are when Feb with 28 days or 29 days comes in between or a the calender year changes etc. I do not know how to cater to this without much diffuculty. Till now we are havong a number of if's and else's in the .osq Looking forward to hearing from you thanks Hi,

I started looking into its use when I was a full-time ingres user, but was seriously put off by the lack of easily-comprehensible documentation. Having used both SQL Server and Oracle in recent years, I believe that this is one of the areas in which ingres currently falls short of the opposition, but where, I'm sure, it could be brought up o strength very easily. My feeling about ingres was always that there were people in the know, when it came to serious in-depth knowledge about the product, but they were either unwilling to share that knowledge, or unable to see the reason for others to need to know that information. Ingres needs its own Jonathon Lewis ! It’s a shame IMA isn’t better known and used.
