Condition Date

[mario-sarkis]

Hey all ,

If I have a table with a daily Date Example:

the table contain ID Balance and Date  and the date has form as (01/01/2016)

I need to extract for previous month the Balance as at end of month and for the maximum for current month from the script since the table from database is too large and I want to extract to table with these condition .

How can I write the "Where" Condition ?

Hope you can help

Thanks,

let's say each ID has a balance evry day but I need to extract from my database to table that contain the balance only for end of each month and for current month the maximum date (not the whole month) below the table and my output would be red cells hope you can help thank you so much :

May be something like this:

Table:

LOAD ID,

           Date,

           Date(MonthStart(Date), 'MMM-YYYY') as MonthYear,

          Balance

FROM .....;

Right Join (Table)

LOAD ID,

           MonthYear,

          Max(Date) as Date

Resident Table

Group By ID, MonthYear;

There are multiple other ways to do this... but this should give you a table with only max date for each MonthYear and ID....
