Hi All,
I have a table called Table1 where I have five fields like Tableid, Processigndate, Amount, remainingCollectonCount and Frequency. All total I have more than 5Lacs records.
Now I need to fill up another table Called FutuecashFlow taking the records from Table1. There will be also five Columns like FutureCashflowid, Table1id, Processigndate, Amount.
Now the condition is that if the remainingCollectonCount =6 and the frequency is 12 then there will be the 6 entries in the futurecasflow table where the prcessign datae wille be addeed by 1 month.
For example Table1
Tableid, Processigndate Amount remainingCollectonCount Frequencu
1 2014-02-15 48 8 12
the future cash flow table the prcessing date column will be shown in the following way
Processigndate
2014-03-15

Why did you skip 2014-08-15 in the example above?

Hi Jeff,

I have forgot to mention it....Sorry for that.

if the remainingCollectonCount =8 and the frequency =12 then in the futurecashflow table the next 12 months will be added by 1 month. if the frequency =3 then processingdate in the futurecashflow table will be added with a jump of 3 months.

in this way I want to populate my futurecashflow table.

So why didn't you skip 2014-03-15 for the original record of 1 2014-02-15 48 8 12?

I'm pretty sure this can easily be done without a cursor but I just don't understand your rules.
